Forecast

San Salvador lies in a high valley among volcanic slopes, about 650 meters above sea level. Its elevation keeps temperatures milder than on the nearby Pacific coast. Moist ocean air reaches the city, while surrounding hills shape local winds and rainfall.

During the rainy months, the northward-moving tropical rain belt and nearby low-pressure areas draw moist air inland, often bringing afternoon downpours. In the dry season, more stable high pressure limits rising air and rain. The valley can hold clouds and haze when winds are light.

Rain usually increases from May through October, with afternoon or evening storms. A brief drier period can interrupt the rains in July or August. From November through April, skies are clearer and rainfall is scarce, though passing Pacific weather systems can bring clouds or showers.
