Meteo San Salvador in maggio

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.

Forum posters describe December as one of the nicest months to visit El Salvador - the rainy season has ended by this point, but the countryside stays lush and green, and temperatures run genuinely pleasant. Posters generally name November as the start of the dry season here, with excellent weather building through the following months, positioning December squarely within that favorable stretch. Given the limited detailed trip reports specific to San Salvador the city, this broader country-level dry-season framing - green scenery without the rain, comfortably warm days - is the most useful guide available for a December visit.
