Tips for living with Mexicali's climate
Keep your home cool
Using thick or light-colored curtains can help block the sun's rays and keep interiors cool. Installing air conditioning or fans is essential for dealing with the high temperatures. If that is not possible, traditional techniques, such as opening windows in the early morning or at night, can help ventilate the house.
Constant hydration
Heat can cause dehydration quickly, so it is important to drink enough water throughout the day. Carrying a water bottle with you and avoiding sugary or caffeinated drinks is key to staying hydrated.
Appropriate clothing
Wear light, light-colored clothing, preferably cotton or linen, which allows for breathability and helps keep the body cool. It is also recommended to wear hats or caps and sunscreen to avoid the effects of direct sun.
Avoid the sun during the hottest hours
During the summer months, it is best to avoid going out between 12:00 p.m. and 4:00 p.m., when the heat is most intense. If you need to be outdoors, seek shade whenever possible and take frequent breaks.

The hottest temperature reached in the city exceeded 50 degrees, making it a place where extreme heat is not an exception, but part of daily life during the summer.
These extreme temperature spikes usually occur in the months of June, July, and August, when heat waves are most intense. Mexicali's all-time record was set in the summer of 1995, when the city recorded a temperature of 52 degrees Celsius.
When does the heat subside in Mexicali?
The heat in Mexicali begins to decrease starting in late September. October and November are transition months, with warm days but cool nights that allow residents to enjoy the outdoors more. By December and January, temperatures reach their lowest point.
