San Salvador in September
Not the best time
Another challenging month weather-wise with daily rains and high humidity. Independence Day celebrations provide some cultural highlights, but outdoor exploration remains difficult.
Weather
September maintains the rainy season intensity with temperatures at 29°C during the day and 19°C at night. Afternoon thunderstorms are reliable as clockwork. The air stays thick and humid throughout the day.

All Months
November through April is dry season – your best window. Temperatures hover around 75-85°F with minimal rain. December and January are peak months when locals take vacation, so book accommodations early. March and April get hotter but still manageable.
May through October brings heavy afternoon rains and humidity. But this isn't necessarily bad. The landscape turns green, waterfalls flow stronger, and hotel prices drop 30%. Just pack an umbrella and plan indoor activities for late afternoons.
Avoid September and October if possible. These months see the heaviest rainfall, and some mountain roads to volcanoes become impassable. Hurricane season also peaks during this period, though direct hits are rare.
Semana Santa (Easter week) shuts down the entire country. Banks, museums, and many restaurants close. But if you're here during this time, you'll witness elaborate religious processions through Centro Histórico.
