Hourly Pressure Trends
Track the barometric pressure in Mexicali hour by hour across the next 6 hourly readings.
Mexicali lies in the low, flat Colorado River Valley beside the Sonoran Desert. Dry land and little shade let strong sunshine heat the ground quickly. Mountains to the west shape air movement, while open desert allows dry winds and dust to cross the valley.
In summer, high pressure often pushes air downward, keeping skies clear and rain scarce. Heat can also create lower pressure near the ground, but this rarely brings steady rain. Moist air from the Gulf of California sometimes arrives and brings short, heavy storms.
Winter brings cooler days as Pacific storm systems move inland. Their lower pressure can bring clouds, wind, and occasional rain, followed by clearer skies. Spring and fall are changeable: temperatures shift quickly, dry spells return, and winds may strengthen as pressure systems move through.
