Antigua Guatemala in January

November through April gives you the sweet spot — dry skies and comfortable temperatures perfect for walking these cobblestone streets. December and January bring the coolest weather, with mornings that might require a light jacket. But this is also peak season, so book accommodations early and expect higher prices. March and April heat up but stay manageable at this elevation. The rainy season from May to October doesn't mean constant downpours — more like afternoon thunderstorms that clear by evening. But muddy volcano hikes and slippery cobblestones make this less ideal for most travelers. Holy Week in March or April transforms the city into Guatemala's biggest cultural celebration, with elaborate alfombras (carpet processions) covering the streets in colored sawdust and flowers.
