A very useful article about the summer weather in San Miguel de Allende, was published by Mittie Roger on Sean and Mittie, a blog about their adventures as a couple living in San Miguel and traveling across Mexico.
San Miguel de Allende is located in the semi-desertic Sierra Madre Mountains, and famous for its consistent year-round 70 degree blue skies, if you come in summer you’re in for a surprise.
Summertime in San Miguel is the rainy season. That used to mean that it wasn’t so different from the regular year-round cool in the mornings and evenings and hot in the middle of the day, punctuated by a 4pm-5pm rain and usually a few hours or rain in the middle of the night (between 1-4 am).
If visiting during this season there are some advantages:
1. Everything is green and lush, unlike our normal sun-baked dirt.
2. You probably live somewhere hot. It isn’t hot.
3. Rain adds some moisture to the air, toning down the surprising dryness of the San Miguel air.
4. Natural reserves, like Charco del Ingenio Botanical Gardens, and outdoor activities, like hiking Las Cabras, can be better with some clouds in the sky and moisture in the earth.
5. It’s a great excuse to grab a good book and stake out a cozy café in one of the colonial buildings to watch the rain come down.
