These conditions are for Guanajuato, about 30 km away from San Miguel. Usually the weather is quite similar in the two locations.
San Miguel has a pleastant year-round spring-like climate. The average day is brisk in the morning, warm and sunny afternoons, and cool nights. At 6400 feet, both the humidity and the temperature is kept down and the air is clean and refreshing. Many tourist from North American come to San Miguel in the winter, where they can enjoy nice days in the 70s instead of the snow and the cold. But the winter nights still afford time in front of the fireplaces in the many bars, cafes, and bistros in town, and most find a sweater still neccessary when the sun goes down.
The rains arrive after the hot dry month of May, and San Miguel goes through a transformation into an oasis paradise. The rains continue, usually a brief shower in the late afternoon, until the month of September. Besides this, every day seems like a little slice of heaven on earth.
