he best sailing season in Lancelin is from December to February (inclusive).
During this period the area gets regular strong sea breezes. Typically
these are of the order of 18 - 25 knots. This means that sailors (at least
wave sailors) are using 4.5 - 5.0 sq m sails. Slalom sailors use whatever
Slalom Sailors use. The sea breeze comes in at
anywhere between 10 am and 3 pm, usually at about 11am.
The typical scenario starts with a land breeze (offshore) blowing during the
night, and a sudden wind as the sea breeze comes in. This sea breeze
comes from the S/W, which is cross shore for the main sailing area.
