Temperatures are generally mild with summer daytime highs in the upper 90's and nighttime lows in the 50's. Winter daytime highs range in the 50's to 60's and nighttime lows are typically in the upper teens or low twenties but can dip into the subzero range. Moisture is evenly distributed, half during the winter as snow, half in the summer as rain.

One of the outstanding features of the climate here is the exceptionally wet summer monsoon. Nearly every afternoon from July into September, thunderstorms occur in the area. Generally this summer rainfall is the result of moist and unstable air originating from the Gulf of Mexico. The most intense storms with record amounts of rain develop from low pressure systems over the upper Gulf of California. They are called chubascos. These storms can reach hurricane force, last three days, and are usually confined to a 50 mile area.

During the summer, light clothing for warm days and cool nights is recommended. Rain gear is useful during the rainy season. During the winter, wear warm clothing to cope with wind chill factors below zero, snow and subfreezing temperatures.
