Cabo San Lucas Weather

The arid desert landscape of the Southern Baja Peninsula, with its tropical latitude, year round sunshine and unique effects of being surrounded by ocean on three sides, has a significant impact on Los Cabos' climate. Cabo weather can be likened to that of Palm Springs – agreeable, sunny days with low humidity most of the year with average daytime highs ranging from mid-70s to mid-80s with relatively no humidity.

Nighttime temperatures during December, January and February generally stay in the 50s and 60s, sometimes dropping into the 40s, while in the high mountains surrounding the Capes, frost is common.

During the months of July, August and September, the Cabo weather forecast can be hot and sometimes stormy with average daytime temperature in Cabo San Lucas hovering around the mid-90s, and often topping 100. But the heat wave on land also brings bath-water warm temperatures to the surrounding ocean waters, bringing them above 90 degrees. Nights are sticky and warm with humidity around the 70’s, and the rainy months of August and September also herald the start of hurricane season even though the combined rainfall is often less than three inches.

Cabo weather remains muggy until mid-October when the seasons turn and trade winds reverse direction, causing cooling ocean currents to cool and a shift in weather patterns, bringing welcome relief to locals and tourists alike.

However, due to the unique topography of Lands End surrounded as it is by water, Los Cabos climate conditions can fluctuate widely, depending upon time of day, closeness to the ocean and desert, and location. Because of hills which offer protection from the Pacific gusts, downtown Cabo San Lucas temperature can sometimes be 10 degrees warmer than the cool Pacific Ocean side, while on the opposite side of the cape, San Jose del Cabo is often warmer than Cabo, sheltered inland and buffered by the Sea of Cortez. Meanwhile, artist colony, Todos Santos, located up the Pacific Coast about 50 miles from Cabo San Lucas, is normally much cooler and foggier than its counterpoints on the tip of the peninsula.
