Los Cabos month by month
Average rainfall and the number of days with at least 1 mm of rain, 2006–2025. On this page a month counts as wet when it gets more rain than an average month in that place (more than a twelfth of its year), and dry when it gets less than half an average month. The months in between are the shoulder.
| Month | Rain | Rain days | Average high | |
|---|---|---|---|---|
| January | 7 mm (0.3 in) | 1 | 76°F / 25°C | Dry |
| February | 8 mm (0.3 in) | 1 | 76°F / 25°C | Dry |
| March | 2 mm (0.1 in) | 1 | 78°F / 26°C | Dry |
| April | 1 mm (under 0.1 in) | 0 | 79°F / 26°C | Dry |

Cabo San Lucas is wet in Aug–Oct, shoulder in Jul, Nov–Dec and dry in Jan–Jun.
September is also by far the stormiest month here, so in Los Cabos the rainy season and the hurricane season are very nearly the same event — which is not true of most places on this page. San José del Cabo is not listed separately: it falls in the same grid square, so its numbers would be these numbers again.
The wettest and driest months
Cabo San Lucas: wettest in September (107 mm (4.2 in), 10 rain days), driest in May (1 mm (under 0.1 in), under a rain day). Over the year, Cabo San Lucas gets 284 mm (11.2 in).
Does the rainy season mean storms?
Not by itself — but Cabo San Lucas is on the hurricane map, and the two overlap here. In the 50 seasons to 2025 a tropical storm or hurricane passed within 100 miles of it in 24 of them in September, its busiest month — which is to say that in the other 26, that month was rain and nothing else. Rain is what most of a wet season is: for the storms themselves, see hurricane season in Los Cabos and every storm since 1976.

How these numbers are made
Daily rainfall and temperature from NASA POWER (MERRA-2), averaged over 2006–2025; a rain day is a day with at least 1 mm. POWER works on a grid of about 50 km, so each place here is its neighbourhood rather than its own rain gauge: a coast, a small island or a valley under a mountain can differ from the square it sits in. The months are the part that holds; treat a single millimetre figure as an average, not a forecast. Storm counts are from NOAA’s best tracks (HURDAT2), 1976–2025.
