Baja California is baking through a sustained heat wave, with forecasters predicting highs of 38°C (100°F) in Mexicali and elevated temperatures across the peninsula. No relief is expected in the coming days.
The heat poses real risks, especially for expats and visitors not accustomed to desert conditions. Dehydration, heat exhaustion, and heat stroke can develop quickly when temperatures hold this high. Health authorities advise staying hydrated, limiting time outdoors between 11 a.m. and 4 p.m., and checking on elderly neighbors, children, and pets.
If you must go out during peak hours, carry water and wear light, loose clothing. Shade is sparse in much of Mexicali’s urban core, so plan accordingly. Even short errands can become dangerous if you are not prepared.
Sustained heat at this level drives up air conditioning demand across the region. CFE, Mexico’s federal electricity commission, typically sees load spikes during prolonged heat events, which can stress the grid and raise household electricity bills. Residents on the DAC tariff, CFE’s highest residential billing tier, may see costs climb if usage increases sharply.
Mexicali sits in one of North America’s hottest desert basins, and summer highs in the high 30s are not unusual. But this wave is holding, and repeated days without a cool-down raise cumulative health risk even for residents who know the climate well.
Watch local forecasts and take the heat seriously. Semanario ZETA, a Baja California news outlet, first reported the forecast. BDN will update coverage if state health authorities issue formal advisories.
