อากาศEl Tunco เดือนมิถุนายน

Forum posters describe El Salvador's rainy season, running roughly May through November, as bringing humid conditions with rain that typically falls in the late evening or overnight rather than disrupting the daytime. Posters are consistent that at worst a visit sees a couple of hours of evening rain, with days themselves staying at minimum dry, often sunny and pleasant. Posters do note that November through April or May generally draws praise as the better overall weather window for an El Salvador trip. Posters generally rate June as warm, humid and genuinely rain-affected for San Salvador, but with the rain concentrated enough in the evenings that daytime plans typically go untouched.

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.
