This desert region, surrounded by beautiful water, has little rain. The average annual amount of precipitation is under seven inches. Most of this rainfall occurs from July through October. The summers bring rainy season weather to Cabo San Lucas.
Late summer is also hurricane season. Although Cabo San Lucas weather includes some summer storms, the tropical storms and hurricanes hardly ever hit directly, and usually pass by to the south. When it rains, it
usually doesn't last very long, although the amount of rainfall can be significant. See the Cabo San Lucas Tropical Storms page for more information.
The annual amount of rainfall varies considerably from year to year. Some years there is hardly any rain, while other years have considerable rain, causing the desert to bloom with wildflowers. When the Pacific currents are warmer, warmer air and water temperatures are produced, resulting in more moisture. Such can be the result of El Niño effects.
Prevailing winds in Cabo San Lucas are from the northwest. These are more regular and prevalent during the summer months, bringing refreshing breezes into the Cabo San Lucas weather patterns.
