Weather

The Heartland has a superb climate—rarely does it get overly hot, even in midsummer, and although winter days can get nippy, especially in northern Zacatecas, they're generally temperate.

Average temperatures in Morelia range from 20°C (68°F) in May to just under 13°C (55°F) in January. Zacatecas is more extreme, with winter temperatures as low as 0°C (32°F) and snow flurries every several years, and summer highs of 28°C-30°C (81°F-85°F). Expect cool nights year-round in most of the region's cities.

The Heartland's rainy season hits between June and October and is strongest in July and August. At this time, the semiarid countryside comes to life with pink, yellow, and blue wildflowers, and the farms offer up fresh vegetables and fruits.
