Badoc Island Lefts seasonal overview

Best Surf Season (September & March)

The most favorable windows at Badoc Island Lefts occur during the transitional months of September and March, when the winter northeast swell machine is still active yet the trade winds begin to relax enough to allow a higher frequency of offshore SSW to SW breezes. In September, the average swell height hovers around 1.2m with a period of 7.5s, and the wind blows offshore nearly 43% of the time – a rare alignment. March offers similar dynamics: 1.1m waves from the NNE (55% of the total) coupled with 17% ideal wind. While not pumping, these months deliver the most rideable, clean conditions for a left that demands both a north component in the swell and a southern component in the wind.

Fair Surf Season (October – February & April – May)

From October through February, the northeast monsoon pumps consistent NNE and NE swell into the coastline, with average heights ranging from 1.5m in February to a hefty 2.2m in December. However, the joy is tempered by dominant NE to ENE winds that blow onshore the vast majority of the time – ideal wind percentages drop to between 4% and 15%. The result is often lumpy, wind-affected surf that requires a keen eye for the rare lull in the trades. April and May flip the script: offshore winds become more frequent (up to 36% in May), but the swell shifts southward, losing size and power. Waves drop to 0.7-0.9m on average, with a dominant SW component that struggles to wrap into the NNE-facing beach. Fun-sized days do occur, but consistency is poor.

Low Surf Season (June – August)

The summer months of June, July, and August are the low point for Badoc Island Lefts. While offshore winds from the SSW and SW blow an impressive 46-49% of the time, the swell direction is overwhelmingly from the SW and WSW – a complete mismatch for the exposed northeast beach. Average heights remain modest (1.0-1.3m) and periods sit in the average 6.8-7.4s range, but the waves rarely break with any power or shape. Only weak, short-period wraparound energy from the NNE (less than 3% of total swell) offers any hope, making this period best suited for travel elsewhere or a total gear reset.

Conditions at Badoc Island Lefts in September

September: The Light at the End of the Tunnel

September is the month when the swell finally begins to turn north again. The average height is 1.2m with a period of 7.5s, and while SW still sneaks in at 20.5%, the NNE direction rebounds to 20.3%, with NNW adding 10%. This means a much higher chance of waves actually wrapping into the bay with decent shape. The wind regime still favors offshore flow: ideal wind from the south occurs 43% of the time, with S (14.4%) and SSW (12.4%) leading. The combination of north swell and south wind creates the best surf quality of the summer-to-fall transition. Expect consistent head-high sets with clean faces – a welcome return to form.
