El Tunco weather in January

El Salvador forum threads describe the dry season here as genuinely excellent - sunny, comfortably warm days with little to no humidity, a pattern that holds from around November through the following April. One specific seasonal trade-off worth knowing for anyone visiting Suchitoto in January: Los Tercios Waterfall, a popular nearby attraction known for its unusual hexagonal basalt rock formations, runs essentially dry this time of year - the rocks themselves stay beautiful and worth seeing, but visitors expecting flowing water should time a visit for the wetter months instead if that's the priority.

El Tunco-focused surf guides call December and January the pick of the year: the region's soggier months have just ended, so it's dry-season sunshine and low crowds by Central American standards, with swell still consistent enough to keep the reef breaks at El Sunzal working most days. Waves run a touch smaller than the peak swell months, but clean rather than blown-out, and the water stays warm enough that a rash guard covers it for most visitors. The trade-off for the good weather is a busier stretch right around Christmas and New Year, when domestic tourists from San Salvador fill the town's hostels and beachfront bars. Outside that holiday spike, regulars describe December as close to the year's most reliable combination of sun, manageable waves, and thin crowds. The record: 30.9C days feeling like a sticky 35C, 23.1C nights, just 9.2mm across 2.2 days, a 29C sea, 68 percent humidity and 10.3 hours of sun.
