November to February

Easiest all-round window

These months often make road trips and outdoor city days easier, with less chance of regular afternoon rain. Highlands can feel noticeably cooler than the coast, especially early and late in the day, so pack one light layer rather than assuming tropical heat everywhere.

March and April

Drier days, with more heat to plan around

Road and hiking plans may still be straightforward, but heat exposure matters more. Put exposed walks and hikes early, carry more water than a city day seems to require, and choose shade or pool time for the middle of the afternoon. Easter travel can increase demand, so verify accommodation and transport early.

May to August

Green landscapes and flexible afternoons

Rainy season does not mean all-day rain every day. Build important outdoor plans into the morning, keep an afternoon alternative for wet weather, and avoid making a sunset transfer the only way the route works. MARN notes that multi-day dry spells can occur during the rainy season, particularly around July or August in some climate patterns, so do not plan from a generic rainfall chart alone.

September and October

Leave extra room for weather changes

Keep mountain viewpoints, waterfalls, boat outings, and long road days movable. Check forecasts and official alerts daily, choose refundable arrangements when weather sensitivity is high, and avoid routes that depend on driving an unfamiliar mountain road after dark.

Choose by priority

The best month changes with the trip

Weather is only part of the choice. Surf ability, holiday demand, photography goals, tolerance for heat, and the amount of route flexibility matter just as much.

Volcano hiking

Favor an early start and a current access check in every season. Wind, visibility, volcanic monitoring, and park operations can override a seasonal expectation.

Surf

Choose by ability and current swell, not by a promise that one season is “best.” Beginners need an appropriate break, instructor, tide, and conditions on the day.

Ruta de las Flores

Dry weather simplifies town walks; wetter months can make the highlands lush. Keep waterfalls optional when access, storms, or trail conditions are uncertain.

Beaches and boats

Check the coastal forecast, tides, local flags, currents, and operator decision. Sunshine alone does not establish safe swimming or boating conditions.

What to pack

Pack for elevation and rain, not one temperature

  • Breathable clothing and dependable sun protection year-round
  • A light rain shell and dry bag or waterproof pouch in rainy months
  • Footwear with grip for volcanic gravel, wet stone, and uneven town streets
  • A light layer for highland mornings and air-conditioned transport
  • Offline weather, map, reservation, and emergency information
  • A flexible activity that does not depend on a clear crater or ocean conditions

Temperatures vary less than rain and humidity

The NASA POWER 2001–2020 climatology shows a warm regional baseline all year. The practical change is moisture: approximate rain rises from almost nothing in January through March to 193 mm in May and peaks around 283 mm in September. Relative humidity follows, climbing from roughly 61% in March to 82% in September.

Use this to choose the month and pace. Do not use it to decide whether tomorrow’s crater will be clear. NASA’s grid is regional, and El Salvador’s coast, city basins and western highlands can feel very different on the same date.

Monthly climate chart for the San Salvador-area NASA grid showing approximate rain of 4 millimetres in January, 5 in February, 8 in March, 39 in April, 193 in May, 232 in June, 197 in July, 246 in August, 283 in September, 226 in October, 48 in November and 10 in December; mean temperature stays near 26 to 28 degrees Celsius
Approximate monthly rain is NASA’s corrected precipitation rate multiplied by calendar days and rounded. The temperature line uses its own right-hand °C scale.
Monthly relative humidity chart showing humidity near 61 to 65 percent from January through April, rising above 74 percent from May and peaking around 82 percent in September
Humidity affects how warm a day feels and how quickly clothes dry. Use it to decide what to pack, not to predict rain at a particular hour.

Western highlands run cooler

NASA’s western-highland grid point averages 24.1°C across the year, roughly 2.8°C below the San Salvador-area regional baseline. Ataco mornings and a volcano start deserve a layer even when the coast feels hot.

Rain totals do not describe the whole day

A wet month can still contain bright mornings; a dry month can still bring an unusual storm. Put the most weather-sensitive plan first and keep one nearby alternative.

Month by month

What each month is like in El Salvador

The table above gives the numbers. Here is the same year in plain words, with the holidays that make roads and beaches busier. Rain figures are approximate monthly totals and temperatures are monthly means from the NASA POWER climatology for the San Salvador area, so the coast will feel warmer and the highlands cooler.

The dry months: January to April

January

Dry and easy. Rain averages about 4 mm for the whole month and humidity sits around 65%, which makes this a comfortable time for road trips, town walks, and volcano mornings. New Year's Day is a public holiday. Pack a layer for highland mornings.

February

Just as dry, with about 5 mm of rain, and a little less humid at around 63%. It's a good month for moving between regions, because few plans need a rain backup.

March

Still dry, with about 8 mm of rain and the lowest humidity of the year, around 61%. Afternoons get hot, so hike and walk early. In 2027, Holy Week (Semana Santa) falls in late March. Holy Thursday, Good Friday, and Holy Saturday, 25 to 27 March, are national holidays, so book beach stays and transport early.

April

The warmest month in this dataset, with a mean of about 28.3°C. Rain starts to come back, at roughly 39 mm, so the first storms can arrive. In years when Easter falls in April, Holy Week moves with it and the coast gets busier.

The rainy season: May to October

May

The rains begin. Rainfall jumps to about 193 mm, humidity climbs to around 74%, and the landscapes turn green quickly. It rarely rains all day, so put outdoor plans in the morning. Labour Day, 1 May, is a public holiday, and Canada notes that the Pacific hurricane season starts in mid-May.

June

Wet and humid, with about 232 mm of rain and humidity near 79%. Keep transfers and trails flexible and check the MARN forecast each day. The U.S. State Department dates the hurricane season from June through November.

July

Still rainy, at about 197 mm, though MARN notes that dry spells of several days can happen around July or August in some years. Enjoy one if it comes, but don't build a trip around it.

August

Green-season travel, with about 246 mm of rain. Early August is San Salvador's festival week: 3 and 5 August are holidays in the city of San Salvador, and 6 August, the feast of the Divino Salvador del Mundo, is a national holiday. Expect busier roads and beaches around those days.

September

The wettest month in this dataset, at about 283 mm, with humidity near 82%. Leave extra room for weather changes, especially for mountain roads, boat trips, and waterfalls. Independence Day, 15 September, is a national holiday.

October

Still wet, at about 226 mm of rain and 81% humidity. Stay flexible around roads, boats, and mountain views, and avoid routes that depend on driving unfamiliar mountain roads after dark.

Drying out: November and December

November

A turning point. Rain drops to about 48 mm, and the mean temperature falls to about 25.8°C, the coolest in the table. Sources differ on exactly when the rainy season ends: MARN and the U.S. State Department give May to October, while Canada says May to November, and both governments include November in the hurricane season. The Day of the Dead, 2 November, is a national holiday.

December

Dry again, with about 10 mm of rain, and a popular time to travel. Christmas Day is a public holiday and holiday dates fill early, so book beach and highland stays well ahead.

Holiday dates from the Código de Trabajo (Art. 190) and the Ministry of Labour; hurricane and rainy-season dates from MARN, the U.S. State Department, and the Government of Canada. Checked 12 October 2026.

A few useful answers

Answers about dry and rainy seasons, surf, festivals, heat, and weather changes.

When is the rainy season in El Salvador?

MARN identifies May through October as the rainy season. November through April is usually simpler for road days, volcano hiking, and town walks. Rain is not constant, and dry spells can occur inside the wet months.

What is El Salvador like in July or “summer”?

July and August sit inside the rainy season, so plan outdoor time in the morning and keep an afternoon alternative. MARN notes that multi-day dry spells can still occur then. Heat is year-round; pack for rain and elevation rather than a northern-hemisphere summer.

Who needs to think most carefully about the season?

Travelers planning volcano hikes, surfing, festivals, road trips, or outdoor days during the rainy season will get the most from this guide.

What can change close to travel?

Rainfall, storms, trail access, surf, festival dates, and road conditions can all change, so check the relevant local source near departure.

How early should I choose dates?

Book early for major festivals or fixed school-holiday dates; our festivals and events guide covers the main celebrations. Otherwise, choose the season first and leave individual outdoor days flexible.
