Guatemala City in October

November through April is your sweet spot – dry season means clear skies and those postcard views of the surrounding volcanoes. December and January are perfect: cool mornings, warm afternoons, and virtually no rain. But here's what locals know: the "rainy season" from May to October isn't the washout you'd expect. Most rain falls in late afternoon thunderstorms that clear quickly. The trade-off? Everything's greener, there are fewer tourists, and hotel prices drop by 30%. Just pack an umbrella and embrace it. Avoid September and October if you can – that's when the rains are heaviest and some mountain roads become impassable.
