Mexicali's Climate
Mexicali lies inland in Baja California in northwestern Mexico, hard against the US border in the heart of the Sonoran Desert, giving it a harsh hot desert climate (Köppen BWh). Summers (June–September) are brutally hot, with daytime highs of 42–46°C that can top 48°C and air so dry that sweat evaporates instantly, while winters (December–February) are pleasantly warm around 20–24°C by day, though nights can dip below 5°C. Annual rainfall is very low, falling mostly during late-summer monsoon thunderstorms or occasional winter rains, and dusty winds are a familiar feature.
