Domes - surf spot statistics

Best Surf Season (November - March)

The heart of the North Pacific winter drives the most consistent and powerful swell energy toward the Hawaiian Islands, and while Domes misses the direct blast of the predominant NW swell, it still feels the pulse. During these months, average swell heights climb to a solid 1.5m with periods averaging 10 seconds, offering punchy, rideable waves. The swell is dominated by a persistent NE trade wind regime, which wraps into the WNW-facing beach, producing lined-up surf that can get fun, good, and solid especially when the swell bumps up to the 1.5-2.5m range. Offshore winds from the east sector blow cleanly across the bay a majority of the time, making for glassier conditions on the best days. While the classic long-period NW groundswells are rare here, the steady NE pulses combined with favorable winds create a reliable winter surf window.

Fair Surf Season (April & October)

These transitional months see a drop in overall size, with average swell heights around 1.2-1.3m and periods in the 9-10 second range. The NE swell machine still dominates, but the power is less consistent. April and October offer a good chance of small, fun-sized waves that are rippable on a high-performance shortboard. The wind remains predominantly from the east, keeping the surface clean. These months are a sweet spot for avoiding the winter crowds while still scoring fun, groveling waves when the trade winds kick up the local fetch.

Low Surf Season (May - September)

Summer settles in with a distinct shift to smaller, weaker swells. From May through September, average wave heights hover around 1.0m and periods drop below 8 seconds, producing choppy, low, messy surf at times. The swell is overwhelmingly from the ENE and E directions (over 80% of events), which offers little to no swell from the optimal W to NW window. The good news is that the wind is ideal 80-90% of the time, with gentle offshore breezes from the east. However, the lack of size and period means the waves are often small and groveling – better suited for longboards or foil boards. True pumping or firing conditions are exceedingly rare during these months.

February: Deep Winter Consistency

February continues the deep winter pattern with an average swell height of 1.5m and period of 9.8s, very similar to January. The swell energy is again dominated by the NE quadrant, with NE and ENE directions accounting for nearly 60% of all wave events. The wave height distribution shows a healthy spread from 1m to 2m, meaning solid, rideable surf is frequently on tap. The wind regime remains predominantly from the east and ENE (50% combined), providing clean offshore conditions for a good chunk of the time. The ideal wind statistic holds at 62%. While the swell direction is not optimal, the combination of size and long period allows for powerful, punchy waves that can be excellent when the trades align. Occasional winter storms deep in the North Pacific can send longer-period swell into the 12s range, adding extra juice. This is a prime month for scoring firing conditions if you time the swell right.
