I have found over the years that occasional trips can't get to Richelieu Rock early season, but not very often. Visibility is better in early season, calmest weather tends to be February - March. April is an odd month when weather can change, though normally the southwest monsoon does not start until into May, I recall mid April on my first year here (2000) we had bad weather by mid April. Seems to me that the "low" season starts later more often now. Early season rough seas are sometimes caused by strong northeast winds as the season switches. It's not often *too* rough though, but to be safer, best to think of Feb - March. ...
Thanks so much .. I am changing plans now and considering other locations to dive in November
