Hurricane season is over, officially
The National Hurricane Center says "The official hurricane season for the eastern Pacific basin is from May 15 to November 30, but tropical cyclones occasionally occur before and after these dates, respectively." So we still keep an eye on the official sources, and we post anything that matters on our live page.
From living here: December is when Cabo feels like a holiday card. Sunny days, cooler nights, and the town gets festive.
