Guadalajara, the capital of the Mexican state of Jalisco, has an elevation of 5,100 feet above sea level which gives it a temperate, spring-like climate throughout the year. It rains frequently during the summer, winters have cooler temperatures, fall is generally pleasant, and the spring season sees the highest temperatures. Regardless of the season, evening temperatures tend to be substantially cooler than during the daytime due to the elevation, and the humidity level is much lower (and more pleasant) than what you’ll experience along the coast.
As is common throughout Mexico, elevation plays a major role in determining climate, so if you’re looking for a respite from the heat, you can travel up in the mountains for some cool mountain air, such as on a day trip to Tapalpa, or if you want warmer weather, go closer to sea level, perhaps with a trip to Puerto Vallarta.

Rainy Season in Guadalajara
Guadalajara’s annual rainfall is just under 40 inches, the majority of which falls between June and September. During that time, there may be torrential storms and the occasional hail. When a storm hits, there may be flash floods that slow traffic. It rarely rains all day, most often raining in the late afternoon or evening and generally lasting no more than a couple of hours. The rain brings refreshment from the heat of the day, cooling things off. The increased rain has the added advantage of transforming the landscape, turning the dry, brown countryside lush and green. Major weather events are rare in Guadalajara, but it can receive copious amounts of rain when there are hurricanes or severe tropical storms along either coast.
Spring in Guadalajara
This season has the warmest weather. It starts warming up in April, and by May, high temperatures may reach the high 80s and low 90s F (mid-30s C). March and April are typically dry, but humidity increases as the months progress, and by the end of May, the rainy season is getting started. Although the climate in Guadalajara can be hot, it is rarely uncomfortable and humidity levels are reasonable. Tourist crowds lessen in the springtime, although the week before and the week after Easter are a busy time for national tourism.
What to pack: You’ll want to wear comfortable clothing for warm weather, such as short-sleeved blouses, T-shirts, pants, skirts, and dresses made of cotton or linen. Local people tend to dress rather conservatively in Guadalajara (as is the case in most of Mexico’s inland cities), so if you choose to wear shorts, it’s a good idea to make them Bermuda length. Don’t forget to pack sunglasses, sunscreen, and a hat. You should also pack a waterproof jacket, especially if you’ll be visiting toward the end of the season.
Summer in Guadalajara
Contrary to what you might expect, the temperature decreases during the summer months, with average highs in the low to mid-80s F (30 C) and dipping down to the low 60s F (15 C) at night. This season sees the most precipitation, with an average of six to ten rainy days each month. Since the rain mainly falls in the afternoon and at night, it’s a good idea to go sightseeing early in the day. June has the longest days of the year in Guadalajara, with an average of 13.4 hours of daylight. June through August is the slowest season for tourism in Guadalajara, so travel and accommodations may cost less than usual.
What to pack: Pack a rain jacket or umbrella along with your warm-weather clothing and a sweater or fleece to wear in the evenings. Choose clothing in fabrics that dry quickly, and pack an extra pair of shoes in case the ones you’re wearing get drenched.
Fall in Guadalajara
Rainy season continues into September, tapering off toward the end of the month. October will see the last rains of the year, but substantially less than previous months. Temperatures cool off through the fall, though you’ll enjoy pleasant sunny days with highs ranging between the mid-70s F and high 80s F during the day. Temperatures may dip down to the 50s F at night.
What to pack: Bring a light sweater or jacket for cool evenings and early mornings. Along with your warm-weather clothes, you may like to have some long pants and long-sleeved shirts.
Winter in Guadalajara
This is the coolest season in Guadalajara. It’s generally still warm and sunny in the middle of the day, however, temperatures dip around sunset. You’re unlikely to see temperatures drop below 40 degrees F (4 degrees C) on the coldest days of the year in January, but it’s quite likely that it can go up to 75 degrees F (24 degrees C) at midday. Snowfall is extremely rare in Guadalajara, but not impossible.
What to pack: Visitors traveling to Guadalajara in the winter should dress in layers since the evenings are much cooler than the days. Jeans or other long pants are a good idea as well as a T-shirt that you can layer up with a long-sleeved shirt and warm sweater for chilly evenings. Carry a jacket or fleece just in case.
