The average temperature in Chapala and Ajijic is in the low 70 degrees. The local weather station in located in Riberas Del Pilar, between Chapala and Ajijic, and has a website where you can check the weather every day. You can also see historical, monthly weather patterns and rain amounts, etc., do you could see a pretty good idea of what the weather is like.
The low temperatures in the winter gets into down to around 50 degrees at night and sometimes even in the 50s when we have a cold front. In the day time, in the winter, the temperature gets around 50 degrees unless we have some cloud cover, which is rare but can happen when there is a storm out there.
The general winter weather goes from 50 degrees at 5 AM to 75 degrees at 4 PM. In the evening, you would want to wear a jacket or a sweater and in the morning, you put on your slippers. Some people have fireplaces that they use occasionally during winter.
Spring starts warming up in mid-February to March, so then you would hang up your light jackets and not touch them again until around November. Temperatures during spring are from 50 to 60 degrees at night and around 80 degrees during the day. Out hot months are the middle of April, May, and early June where the temperature ranges from 90 to 94 degrees, which is the highest temperature that I have seen in 7 years. We do get a little more humidity in May as it builds up towards the rainy season. May is probably the most uncomfortable month here as far as the weather goes.
Rain starts in June and lasts for up to 4 months. During this time, it rains almost every day and mostly in short bursts or at night. The temperatures during rainy season are in a very narrow and comfortable range, which is around 72 to 87 degrees all summer. The summers here is a warm time but a lot of the year-round residents like our climate in the summer better than any time of the year.
During fall or in October, the rains stop and the days start to get shorter and over time it gets cool again into November. Fall is very nice as things are still green from the rain.
Overall, the weather here in Chapala and Ajijic all year round is pretty nice and very comfortable.
