Meteo Copán (Copán Ruinas) in giugno

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.

Copán Ruinas forum posters are consistent that July, though squarely in the rainy season, doesn't mean a lost day: mornings are usually clear and pleasant for touring the ruins, with the rain typically arriving as a dramatic hour-or-two downpour in the late afternoon or evening. One traveler specifically said full-day rain or drizzle was rare during their visit. The advice that comes up again and again is to plan ruins-and-outdoor time for the morning and treat the afternoon storm as a good excuse for a long lunch, since it genuinely shouldn't derail a trip.

Forum posters describe November through March as a genuinely nice stretch here, with January - the coolest month of the year - still comfortably mild rather than cold, thanks to the town's highland setting keeping temperatures well short of the lowland heat found elsewhere in Honduras. Posters consistently recommend staying in Copan Ruinas town itself rather than the outskirts, calling it a pleasant, walkable base for exploring the nearby Maya ruins. One forum thread specifically discusses planning a January/February trip to Honduras as a winter escape, with posters framing this window as a reliable, comfortable choice for ruins-focused sightseeing.
