Boulevard - surf spot statistics

Best Surf Season (July - October)

During these months, the synoptic pattern shifts, bringing a marked increase in offshore wind frequencies from the west and southwest. While average swell heights dip to a modest 0.7-1.1m, the wave periods remain solid in the 9-10 second range, offering clean, well-ordered lines when the wind aligns. The trade wind inversion weakens, allowing more frequent passages of light offshore breezes, especially from the WSW and WNW. This is the window where Boulevard can actually offer fun, rippable waves, though you'll need to pick your days carefully as the swell direction is still predominantly from the east. It's a classic 'quality over quantity' scenario - smaller but cleaner waves that reward patience and a sharp eye on the forecast.

Fair Surf Season (May - June & November)

These transitional months see a mix of conditions. The offshore wind window expands slightly in May and June (14-27% ideal) but the swell is often smaller and weaker, with heights averaging 0.7-0.9m and periods around 8.6-9.0s. November sees a significant uptick in swell size (average 1.5m) and period (9.9s), but the offshore wind frequency drops to 14% as the northeast monsoon begins to strengthen. During this season, you might score a few decent sessions when a west swell coincides with a light offshore breeze, but consistency is low. It's a gamble - either small and clean or bigger and messy.

Low Surf Season (December - April)

The heart of the northeast monsoon dominates this period. The trade winds howl from the NE and ENE, blowing directly onshore at Boulevard, which faces east. Swell heights are at their largest (1.2-1.8m) and periods are decent (9.2-10s), but the relentless onshore wind chops up the surface and destroys any hope of a clean face. Ideal offshore wind from the west is virtually non-existent (2-7% of the time). The waves are powerful and have good size, but they are nearly always messy and difficult to surf. Only a rare cold front or low-pressure system swinging through the South China Sea can briefly flip the wind offshore, offering a fleeting moment of quality amidst the chaos. For most, this is a time to look elsewhere or enjoy the raw power from the beach.

August: Offshore Winds Peak, Swell Holds Steady

August continues the summer pattern with the highest percentage of offshore wind - a solid 57% of the time. The wind blows ideally from the WSW, SW, and SSW, with light to moderate speeds. This is Boulevard's prime window for clean conditions. Swell heights average 0.7m, but the period stretches to a very respectable 9.7s. The longer period means even the 0.5-1m waves have some push and shape. Swell direction remains from the east (E 35%, ENE 31%), but the offshore wind grooms these waves into clean, orderly lines. Small but rippable. The consistency of both swell and good wind is at its annual high. If you're looking for a surf trip to Boulevard based on reliability, August is the month to target.
