The Tropic of Cancer passes through Todos Santos, some 50 miles north of Cabo San Lucas. Forecast Los Cabos' weather is influenced primarily by its tropical latitude and the effects of the surrounding ocean on local weather patterns.
Weather is mild, sunny and dry most of the year, hot and sometimes stormy in the summer.
Conditions can vary widely, depending on location, time of day, and proximity to ocean and desert. The Pacific Ocean side of Cabo San Lucas, for example, is often ten degrees cooler than the downtown marina area, which Cabo's hills protect from chilly Pacific breezes. San Jose del Cabo, on the Sea of Cortez just 20 miles northeast of Cabo San Lucas, is often a few degrees warmer than San Lucas. Todos Santos, fifty miles north on the Pacific coast, is usually much cooler. Fog is rare in San Jose and San Lucas, but common a few miles north, along the Pacific.
