What to expect
Between April and October the seas are generally friendlier and boat schedules are steadier. This is also the busiest period, and fast boat tickets can sell out from April to June, so book early.
From roughly December to February there is more wind, waves and rain. You can still dive, but sites and timing can change and boats may be affected. March and November tend to be a changing period in between.
