Antigua Guatemala Weather by Month: A Real Dry Season From November, and Cool Nights All Year

What is Antigua's year like?

Antigua has two seasons, and the dry one is the one nomads come for. Temperature barely moves; rain does. Here is the year, with the high and low temperature and the rain:

Read the rain first. November to April is close to dry, with the cleanest stretch from December to March, and May to October rains hard, with two peaks: June (211 mm) and September (237 mm). The reason for the flat temperature line is altitude: Antigua sits in the Guatemalan highlands, so it is mild by day and cool at night in every month, not hot.

When is the dry season, exactly?

November to April. In December, January and February there are 0 to 2 rainy days a month, and cloud is at its lowest of the year. A rainy day is a day with at least four millimetres of rain, so a short shower does not count.

November is the shoulder: 29 mm and about 4 rainy days, so you may see the odd wet afternoon. April is the switch. It is the warmest month, with a 27°C high, and it already gets 30 mm on about 5 days as the first storms build. If you arrive in April, expect a dry, bright start and a wetter end to the stay.

How wet is the rainy season, really?

Wetter than the postcards. From May to October rain falls on 12 to 19 days of each month, and September is the worst, with 237 mm on about 19 of 30 days. We hold monthly totals, not the time of day, so we cannot say the rain always comes in the afternoon; plan for wet spells that can last more than a day.

October is when it starts to ease, and by November it is a different town. If you work from a café terrace or a rooftop, that is the practical difference: from December to March you can plan to sit outside, and from June to September you cannot.

Is it warm in Antigua?

By day, pleasantly: highs of 23°C to 27°C all year. By night, no: the low is 13°C in December and January, so bring a sweater for evenings and early mornings, and expect to want a blanket where a house has no heating. In the wet months nights are a little warmer and days a little cooler, and it is damp.

That mix is the opposite of the coast. If you want a hot beach month, this is the wrong town. If you want to sleep well, the cool nights are a plus, and a light fleece is the one thing worth packing, along with a rain jacket if you come between May and October.

How does Antigua compare with Tulum and Bogotá?

The table puts January side by side for two other Latin American bases.

Against Tulum, Antigua is drier in January but cooler by day and much cooler at night. Against Bogotá, which sits higher still, Antigua is warmer and far less rainy.

What should a remote worker do?

Our take, on weather alone:

• Want a dry, bright month with cool evenings: December to March. January and February are the safest.
• Want to avoid the rain but pay less: November and April are the shoulders. Pack for one wet afternoon a week.
• Want to stay in the wet season anyway: expect rain most days from June to September and plan work around it; October is the first easier month.
• Want hot beach weather instead: see where is warm in January.
