Picture the first day of summer: warm but never sweltering, the kind of warm where you barely notice the air. Cold Coronas, perfect popsicle weather. In Cabo San Lucas and the rest of Los Cabos, it feels like that almost all year, and the local vibe matches the weather.
Check the live conditions and forecast below, then plan your day:
Cabo San Lucas is located on the Tropic of Cancer. The average high in Cabo ranges from 74 to 85 °F (23 to 30 °C), the average low ranges from 63 to 78 °F (17 to 26 °C), and the average relative humidity ranges from about 62% in spring to 80% in September.
The Los Cabos area is flanked on the west side by the Pacific Ocean and on the east side by the Sea of Cortez (Gulf of California), with the Sierra de La Laguna range cutting through the center of the Cape Region at the end of the Baja peninsula. This produces microclimates on either side of this peninsula, so temperatures on the Sea of Cortez side and Pacific Ocean side can vary as much as 15 °F.
The Los Cabos area is surrounded by desert plains so it receives very little rain and lots of sunshine. The climate is arid with over 300 days of sunshine, with some weather reports of over 350 days. The average annual rainfall is about 11.6 inches (295 mm), with more rain occurring during the month of September than the other months.

Hurricane season in Cabo
Hurricanes and tropical storms can come through the Los Cabos area. The hurricane season in the Eastern Pacific Ocean officially runs from May 15 to November 30, according to the National Oceanic and Atmospheric Administration (NOAA), however, most hurricanes develop later in the season due to the higher sea surface temperatures. Peak activity is typically from August to October, highest in September, and direct landfalls on Cabo San Lucas are relatively rare.
NOAA constantly monitors for hurricanes and tropical storms in the Eastern Pacific and uses forecast models to determine the likely trajectory and strength of the storms. This information is reported out in public advisories every few hours on the National Hurricane Center’s website.
The United States Air Force also sends reconnaissance aircraft over potential hurricanes to collect additional data, which is also reported in the public advisories. This allows for an adequate warning, usually on the order of many days, for the approach of a storm or hurricane.
The strongest recent example was Hurricane Odile in September 2014, which is tied for the most intense tropical cyclone to make landfall on the Baja California Peninsula in the satellite era. About 26,000 foreign tourists were stranded in the area.
Most businesses in Cabo just play through during a storm or even a hurricane, remaining open either through or right up until the storm and reopening right after.
