We live in San Diego and usually go to the Mexcian Riviera in early Feb. because I am heat sensitive.
Once we went in early May, and it was hot in Cabo ! However, in 2006, it was already hot in Acapulco in Feb.
On the way down, DH loves to go topside and stand out there, but on the way back to SD it is very windy.
I think the heat factor will be fine in April. Not everyone is a heat wimp like me.
