THE BANYAK ISLANDS receive most of our swells from the low pressure systems traveling across the Southern Indian Ocean between South Africa and Australia. They are seasonal, most frequent and intense from April to October in our peak season, but they also pulse through at other times, usually slightly smaller and less frequent.
November-April often produces swells with more west in them, which is better for the Tuangku/Bay of Plenty breaks, and some unpredictable west swells come at this time from monsoon conditions in the northern hemisphere that we do not get in peak season, but these also produce good surfing. Swell direction is important for the Banyak breaks, in more south swells the Bangkaru breaks such as Treasure Island and Cobras can be six feet while the Bay is almost flat; meanwhile the Bangkaru breaks usually do not like swells with a lot of west in them.
What makes the Banyaks a great off-peak destination is that winds are always variable because we are so close to the equator. There just isn’t much wind around and it is hard to predict it in any seasonal way, though there is a higher chance of storms in the off-peak Oct-Feb time. But unlike Bali and similar latitudes there are no trade winds. This is good because it is very rare to have non-surfing days due to wind, unless storm conditions move in (rare and totally unpredictable, much like cyclones or hurricanes). Offshore conditions can be had in any wind except the rare S/SW, even then it is unusual for them to hang around for more than a day.
You could have some epic barrels to yourselves from November to February. Only three boats operate here so little crowds.
