Hello I have Dove Coz in Feb.Big swells 6 to 8 feet are common.My last trip there 8 out of 12 divers were to sick to make the secound tank. Getting back on the Boat was a stunt mans job.
Diving Cabo at that time in Cabo is OK because The trips are done at the local spots that are protected by the natural formation of the Cabo Bay.This is also why the marina was built there and it only takes 5 min by boat to get to the Dive areas.
Water will be in the around 65 coz is only 5 degrees warmer.
On shore the air Temp.s are in the 80s a little cooler at nite but during the day is shorts,sandles and t shirts.
I Dive with Baja Dive nice 40 foot boat and a great crew.
