At the southern tip of the Baja California Peninsula, the Gulf of California (also called the Sea of Cortez) and the Pacific Ocean meet the subtropical desert of the Los Cabos region, producing a warm, dry and sunny climate year-round. Cabo San Lucas tends to be hotter than San José del Cabo, which is located about 20 miles east of its more famous neighbor.
With over 320 days of sunshine each year, summer high temperatures can exceed 100 F in this area, but the average high in August is 93 F with an average low of 75 F. And like the rest of Mexico, this area also has a rainy season, which is July through October in Los Cabos. But little rain falls in this desert area. The four-month rainy season drops just 6.8 inches of rain. Total annual rainfall for the area is just 9.1 inches.
Winters are beautiful in Los Cabos with an average high of 77 F in January and a low of 55 F for pleasant sleeping weather. No need for winter heating here, but summer demands air conditioning.
Humidity is higher than you might expect for a desert climate, although it never reaches above 70 percent. Just enough to ease those wrinkles but not enough to make you feel uncomfortable.
Winter sea temperatures are cooler than mainland Mexico, dipping as low as 70 F but the desert sun warms the water to the low 80s by summer.
Los Cabos also experiences hurricanes from June through October. The most recent was Hurricane Odile in 2014, a Category 3 storm with sustained winds over 125 mph. Over the last 10 years, five hurricanes have visited the area.
And like most of Mexico, the region can experience earthquakes from time to time.
