Sunday in Cabo: High Humidity, Very High UV and a Chance of Afternoon Storms

Hot, humid conditions, very high UV and a chance of afternoon thunderstorms are in the Los Cabos forecast today. Here’s what to know before heading out.

By Carlos Mendoza | Breaking News

Los Cabos is in for another hot and humid Sunday, with very high UV levels and the possibility of afternoon showers or thunderstorms affecting outdoor plans.

Current forecasts call for daytime temperatures around 33°C (91°F), while humidity could make conditions feel closer to 38–39°C (100–102°F).

There is also a chance of rain and afternoon thunderstorm activity, while coastal winds may become gusty at times.

What visitors should know

For anyone planning golf, fishing, beach time or an outdoor excursion, the bigger concern may be the combination of heat, humidity and strong sun. UV levels are expected to remain very high.

Bring water, use broad-spectrum sunscreen, seek shade during the strongest midday sun and pay attention to changing skies if you are on the water or in an exposed area.

A thunderstorm chance does not mean Cabo will see continuous rain. Tropical-season weather can be highly localized, with one part of Los Cabos seeing a brief downpour while another stays dry.

Boaters should continue checking current marine conditions and instructions from local authorities before departure.

The Cabo Magazine will monitor official weather and Civil Protection updates through the day if conditions change.
