Best time to visit Guanajuato: weather and events

Guanajuato’s monthly mean temperatures range from 13.9 °C in January to 20.8 °C in May, while rainfall varies more sharply over the year. The municipal climate table gives the city’s conurbation monthly means and precipitation totals, so the figures offer a useful month-by-month comparison rather than a forecast for particular travel dates.

January and December have mean temperatures of 13.9 °C and 14.3 °C, with 13 mm and 12 mm of precipitation respectively. February and March are drier in the table, each with 7 mm; their mean temperatures are 15.2 °C and 17.6 °C. April reaches a mean of 19.6 °C with 15 mm of rain.

May is the warmest month by mean temperature, at 20.8 °C, and its reported mean minimum and maximum are 12.9 °C and 28.7 °C. Rain increases to 36 mm in May, then rises considerably in June, when the mean is 20.1 °C and precipitation is 130 mm.

July records 145 mm of precipitation, the highest monthly total in the table, with a mean temperature of 18.9 °C. August and September remain rainy by comparison with the drier start and end of the year: 139 mm and 132 mm respectively. Their mean temperatures are 19.1 °C in August and 18.4 °C in September.

By October, the mean is 17.2 °C and precipitation is 47 mm. November is drier, at 14 mm and a mean of 15.6 °C.

These figures make November through April the driest continuous stretch in the table, while June through September stands out for higher rainfall. For current conditions and any seasonal updates, check the official site before you go.

A recurring civic event recorded for September is an enactment of the Battle of the Alhóndiga, held in Santa Rosa on September 28. If that date is part of your plans, allow room in your schedule for the event and check local arrangements before setting out.

The city’s September climate figures show a mean temperature of 18.4 °C and 132 mm of precipitation. That rainfall total is substantially higher than October’s, so it’s worth keeping the month’s weather pattern in mind when choosing dates around the celebration.

September also falls within the broader period associated with the Festival Internacional Cervantino. Its specific dates and programme aren’t included here, so verify them with the event’s official organizers before booking around a performance.

Día de la Cueva, also called the San Ignacio de Loyola celebration, is a recurring observance on July 31. The municipal report identifies the date but does not give a schedule or describe the programme, so check local event details before making plans around the celebration.

July is also the wettest month in the climate table, with 145 mm of precipitation and a mean temperature of 18.9 °C. June and August are similarly rainy, at 130 mm and 139 mm.

Choose your dates by weighing the monthly climate pattern against the recurring events that matter to your itinerary. The table points to November through April for lower monthly rainfall; July offers a date-specific observance, while September has the recorded enactment in Santa Rosa.

For the hotel-distance reference, a three-star hotel in Guanajuato is about a 7-minute walk from the city centre. Build your plans around the dates and areas you want to visit, then confirm event schedules and weather before departure.
