A hurricane is a powerful storm that starts over warm ocean waters. Near places like Cabo and Los Cabos, along the Baja California peninsula, the Sea of Cortez (also known as the Gulf of California) can get very warm, especially in summer and early fall. 

When the water temperature is high, it heats the air above it. This warm air rises, creating an area of lower pressure below. As more air rushes in to fill this space, it warms up and rises. This cycle continues, and the swirling air forms a hurricane. 

The warm waters of the Sea of Cortez provide the energy that fuels the hurricane, making it more robust as it moves.

At Los Cabos

I used to live in Los Cabos for some time and worked here as a boat captain in one of Cabo San Lucas' leading tour companies. Back then, I came for 6 months but stayed for 18. I've done a bunch of things, and visited multiple hemispheres. I traveled and lived in other countries. And now I'm back here, At Los Cabos.
