What’s the weather in El Salvador in August?
August in El Salvador presents travelers with distinctive weather patterns characteristic of the country’s tropical climate. The month falls squarely within the rainy season, yet offers plenty of sunshine between showers, making it an interesting time to explore this Central American gem.
Typical daytime and nighttime temperatures
In August, El Salvador experiences consistently warm temperatures with some regional variations. The lowland coastal areas typically see daytime temperatures reaching 30-32°C (86-90°F), whereas the central plateau including San Salvador hovers around 28-30°C (82-86°F). Notably, cooler temperatures can be found in the mountainous regions, where daytime highs typically reach 24-26°C (75-79°F).
Nighttime brings welcome relief from the heat. Along the coast, temperatures generally drop to 23-25°C (73-77°F), making evening beach walks pleasant. In San Salvador and the central regions, expect nighttime temperatures of approximately 18-20°C (64-68°F). The mountain areas get considerably cooler after sunset, with temperatures sometimes dipping to 15-17°C (59-63°F).
The temperature fluctuation between day and night creates a rhythm to August days in El Salvador – hot, sometimes humid days followed by more comfortable evenings. This pattern allows travelers to plan outdoor activities accordingly, with mornings and late afternoons typically being most comfortable for exploration.
Sea temperature for beachgoers
For those planning to enjoy El Salvador’s Pacific coastline, August offers exceptionally welcoming ocean temperatures. The sea maintains a balmy average of 29-30°C (84-86°F) throughout the month, making it perfect for swimming, surfing, and other water activities.
This warm water temperature remains consistent along the entire coastline from La Libertad to El Cuco. The beaches near La Libertad and El Tunco provide excellent surfing conditions during this time, with the combination of seasonal swells and warm water creating ideal conditions for both beginners and experienced surfers.
Additionally, the warmer sea temperatures support vibrant marine life, making August a good time for snorkeling, particularly in protected areas like Los Cóbanos coral reef. Just be aware that afternoon rain showers might temporarily affect water visibility.
How August compares to July and September
August marks the middle of El Salvador’s rainy season, positioning it between slightly drier July and usually wetter September. Compared to July, August typically sees a moderate increase in precipitation frequency and intensity. The average rainfall increases from July’s approximately 230mm to roughly 270mm in August.
Temperature-wise, there’s minimal variation between these three months. July, August, and September all maintain similar daytime temperature ranges of 28-32°C (82-90°F), though August might feel more humid than July.
September generally represents the peak of the rainy season, with rainfall typically increasing to around 330mm, significantly more than August. Furthermore, September carries a higher risk of tropical storms compared to August.
The transition from July through August and into September shows a gradual intensification of the rainy season. While July might offer more consistently dry days, August provides a balance of sunshine and rain, and September brings the heaviest precipitation. For travelers seeking to balance good weather with fewer crowds, early August often presents an appealing compromise between the weather conditions of high season and the authentic, less-touristed experience of rainy season travel.
How rainy is August in El Salvador?
The rainy season reaches its crescendo in El Salvador during August, bringing significant precipitation across the country. If you’re planning to visit during this time, understanding rainfall patterns will help you prepare accordingly and make the most of your trip.
Number of rainy days
August firmly establishes itself as part of El Salvador’s wet season with substantial rainfall throughout the month. Across the country, you can expect rain on approximately 22 days in August. However, the number varies slightly by location. In San Salvador, rainfall occurs on about 24.2 days of the month, while Santa Ana experiences rain on approximately 23.5 days. San Miguel sees slightly fewer rainy days at around 23 days.
The probability of precipitation increases as August progresses. In San Salvador specifically, the chance of a wet day starts at 36% at the beginning of the month and climbs to 44% by month’s end. This gradual increase reflects August’s position as a transition toward September, which represents the peak of the rainy season with a 48% chance of daily precipitation.
Rainfall intensity and timing
When it comes to volume, August’s rainfall is substantial but varies by region. Overall, El Salvador receives about 267mm (10.52 inches) of precipitation during August, averaging to approximately 9mm (0.35 inches) per day. Regional differences are notable – San Salvador accumulates about 159mm (6.26 inches), Santa Ana receives around 142mm (5.59 inches), while San Miguel sees a significantly higher 262mm (10.31 inches).
The rain in August typically manifests as afternoon downpours rather than all-day drizzles. Mornings often start sunny before giving way to heavy showers later in the day. This pattern creates a rhythm to August days – I’ve found you can often plan morning activities with reasonable confidence, then use the afternoon rainfall as an opportunity to rest or enjoy indoor attractions.
In terms of rainfall intensity, a sliding 31-day measurement centered on August shows precipitation increasing from 4.3 inches at the start of the month to 5.5 inches by the end. This reflects the gradual intensification of the rainy season as it moves toward its September peak.
Humidity levels and comfort
High humidity accompanies August’s rainfall, creating a distinctly tropical feel. The average humidity in El Salvador during August hovers around 82%, making the air feel heavier than the temperature readings might suggest. In San Salvador specifically, relative humidity averages 79%.
The combination of warm temperatures and high humidity affects comfort levels considerably. The chance of experiencing muggy conditions in San Salvador increases from 96% at the beginning of August to 99% by month’s end. This high humidity impacts how temperatures feel – the average heat index (which factors humidity into temperature readings) reaches between 38°C (100.4°F) and 43°C (109.4°F).
Consequently, even though daytime temperatures aren’t extreme by tropical standards, the humidity makes August feel particularly warm. Nonetheless, most travelers adjust to these conditions after a few days – I recommend lightweight, moisture-wicking clothing and staying properly hydrated to maintain comfort during your August visit.
Sunlight, cloudiness, and daylight hours

Sunshine in El Salvador during August presents an interesting contrast to the rainy season conditions. Despite being firmly in the wet season, the country still offers substantial daylight and sunshine between rain showers, creating opportunities for exploration and outdoor activities.
Average hours of sunshine per day
El Salvador receives a respectable amount of sunshine in August even amidst the rainy conditions. San Salvador enjoys approximately 8 hours and 17 minutes of radiant sunlight daily, representing about 66.6% of the available daylight hours. At the coastal areas, sunshine hours can reach up to 8 hours and 35 minutes per day. In fact, throughout the month, only about 4 hours and 9 minutes per day see the sun completely obscured by cloud, haze, or fog.
As a result, most mornings start bright and clear before afternoon clouds build up. This sunshine pattern means early risers can maximize outdoor activities by planning them in the morning hours when sunshine is more reliable.
Cloud cover trends
August demonstrates remarkably consistent cloud patterns across El Salvador. The month experiences essentially constant cloud cover, with overcast or mostly cloudy conditions prevailing about 85% of the time. The clearest day of the month is typically August 4th, which still has clear, mostly clear, or partly cloudy conditions only 16% of the time.
For comparison, June represents the cloudiest month of the year with 93% cloud cover, while January enjoys the clearest skies with only 22% cloud cover. In fact, August marks the third consecutive month of the cloudier part of El Salvador’s year, which typically runs from April through November.
This persistent cloudiness contributes to the humid feeling characteristic of August in El Salvador. Yet interestingly, these clouds also moderate temperatures during what would otherwise be intensely hot days.
Sunrise and sunset times
Daylight hours gradually diminish throughout August in El Salvador. The month begins with 12 hours and 43 minutes of daylight on August 1st and ends with 12 hours and 23 minutes on August 31st, representing a decrease of about 20 minutes over the month.
Sunrise and sunset times also shift throughout August:
| Date | Sunrise | Sunset |
|---|---|---|
| August 1 | 5:41 AM | 6:24 PM |
| August 16 | 5:44 AM | 6:18 PM |
| August 31 | 5:45 AM | 6:08 PM |
This data shows the sun setting progressively earlier as the month advances, with sunset occurring 16 minutes earlier by month’s end. This gradual reduction in daylight hours is worth considering when planning evening activities or excursions.
Moreover, the consistency of daylight hours reflects El Salvador’s proximity to the equator. With San Salvador situated at the 14th degree of northern latitude, sunset lasts approximately 25 minutes in August, unlike the extended twilight periods experienced in countries farther from the equator.
Is August a good time to visit El Salvador?
Deciding whether August is the ideal time for your El Salvador adventure depends largely on your preferences and priorities. The month offers a fascinating mix of cultural opportunities alongside some weather-related challenges.
Pros and cons of traveling in August
Pros: August transforms El Salvador into a lush, green paradise ideal for photography enthusiasts and nature lovers. The countryside bursts with vibrant vegetation thanks to the ongoing rainy season. You’ll enjoy significantly fewer tourists at major attractions, leading to more authentic experiences and potentially lower prices on accommodations and activities. For surf enthusiasts, the waves remain excellent despite the rain.
Cons: Afternoon rainstorms are a regular occurrence, which can disrupt outdoor plans. The increased precipitation brings a higher risk of mudslides and flooding, especially in rural and mountainous areas. Some rural roads may become impassable, and certain hiking trails might close for safety reasons. Domestic travel actually increases during this period, potentially leading to premium prices for hotels and larger crowds at attractions.
Major festivals and events in August
August stands out as a culturally rich month in El Salvador. The Festival of El Salvador del Mundo (August 1-6) represents the country’s biggest holiday celebration with vibrant parades, fireworks, and religious ceremonies. In San Salvador, the Agostinas Festivities feature colorful events including the Parade of the Mail (August 1), the Parade of Commerce (August 3), and the traditional “La Bajada” procession (August 5).
Perhaps most unique is the “Balls of Fire” festival in Nejapa on August 31, where locals commemorate a volcanic eruption with an energetic, fiery celebration. These festivities make August particularly busy in El Salvador despite the rainy season.
Tips for dealing with the rainy season
Since rain typically falls in quick, heavy bursts during the afternoon, plan your outdoor activities for the relatively dry mornings. Pack a lightweight rain jacket, quick-drying clothes, and extra pairs of socks. Remember that not all roads in El Salvador are paved, so heavy rains can cause flooding and longer drive times.
Henceforth, be aware that August falls within hurricane season (June to November), so check with hotels about contingency plans and consider travel insurance that covers weather disruptions. Surprisingly, many travelers find the afternoon rain showers refreshing after morning explorations in the tropical heat.
Travel tips for August visitors
Preparing properly for a trip to El Salvador in August requires strategic planning given the unique weather conditions. My years of exploring this tropical nation have taught me several practical approaches to maximize enjoyment while navigating the rainy season.
What to pack for the weather
Packing wisely for El Salvador’s August climate means prioritizing items that handle both heat and rain. Lightweight, breathable clothing forms your foundation, complemented by essential rain gear. I recommend bringing:
- A waterproof jacket or poncho that packs small
- Water-resistant footwear (avoid sandals in rural areas where snakes may be present)
- Quick-drying shirts and pants
- A wide-brimmed hat for sun protection
- Waterproof bags to protect electronics
Indeed, don’t forget insect repellent with CDC-recommended ingredients, as mosquitoes thrive in August’s humid conditions. A travel towel or sarong serves multiple purposes, and carrying a reusable water bottle helps maintain hydration.
Best regions to explore in August
The western areas around Santa Ana typically experience less rainfall (142mm) compared to San Miguel (262mm) in the east. Obviously, coastal regions remain popular due to the consistently warm 86°F sea temperature, making beach destinations like El Tunco appealing even with occasional showers.
Urban centers like San Salvador become vibrant cultural hubs in August, primarily because major festivals occur during this month. The Fiestas Agostinas features parades, marching bands, and food stalls, while the spectacular “Balls of Fire” festival in Nejapa commemorates a volcanic eruption with an exhilarating fire-throwing display.
How to stay comfortable during muggy days
The combination of 84°F daytime temperatures and 96-99% chance of muggy conditions demands adaptation strategies. Schedule outdoor activities during mornings when thunderstorms are less likely. Subsequently, use afternoons for indoor attractions or relaxation.
Staying hydrated is crucial—always carry water and consider adding electrolyte packets if experiencing stomach issues. Finding accommodation with air conditioning provides essential relief from August’s 82% average humidity. Ultimately, monitoring weather forecasts regularly allows you to adjust plans as needed.
Conclusion
Although the weather in El Salvador in August brings significant rainfall, this tropical month offers a unique blend of cultural richness and natural beauty that rewards well-prepared travelers. The consistent pattern of sunny mornings followed by afternoon showers creates a predictable rhythm, allowing visitors to plan activities accordingly. My experience visiting during this season taught me that early morning explorations followed by indoor cultural activities during rainfall create the perfect balance.
Travelers should certainly consider August’s benefits beyond weather patterns. The vibrant greenery throughout the countryside, significantly smaller tourist crowds, and exceptional cultural festivals like Fiestas Agostinas provide authentic experiences unavailable during drier months. Warm ocean temperatures hovering around 86°F maintain excellent conditions for surfing and swimming despite occasional coastal showers.
Nevertheless, preparation remains essential for August visitors. Light, quick-drying clothing, reliable rain gear, and strategic scheduling will maximize enjoyment during this humid period. Urban centers like San Salvador and beach towns such as El Tunco offer the best combination of activities and manageable weather conditions during this time.
