Kincardine - surf spot statistics

Best Surf Season (October – March)

The Lake Huron machine cranks into high gear from October through March, delivering the largest and most powerful swell of the year. Average wave heights climb to 1.0–1.3 m with periods stretching to 5 seconds or more, thanks to strong extratropical systems tracking across the continent. However, the dominant wind directions during these months—WSW, W, WNW, and NW—are directly onshore and often blow hard, ruining surface conditions. The wind is ideal (offshore from ENE/E/ESE/SE) only 2–5% of the time, so clean sessions are fleeting. Still, when a cold front clears the sky and those east-northeast breezes kick in, the west-facing beach can light up with punchy, long-period waves. Patience and a keen eye on the wind forecast are essential, but the rewards are real.

Fair Surf Season (April & September)

April and September represent the bookends of the active storm track. Swell heights average 0.7–0.8 m with periods around 4 seconds, offering rideable but modest surf. Offshore wind percentages nudge up to 4–5%, and the wind fields become more variable as seasonal transitions weaken the dominant onshore flow. These months are a mixed bag—some days deliver clean, waist-high lines, while others remain flat or choppy. For the dedicated surfer, these are windows of opportunity when the lake is less crowded and the odds of a favorable wind-swell alignment are slightly better.

Low Surf Season (May – August)

Summer settles over Lake Huron from May through August, bringing small, weak surf. Average wave heights dip to 0.5–0.6 m and periods hover around 3.5–3.8 seconds, with the majority of energy arriving from the north-northwest—a direction that produces minimal swell at this west-facing beach. Onshore winds from the southwest and south dominate, and though offshore breezes occur occasionally (1–2% of the time), they rarely align with enough swell to create quality waves. This is strictly flat-spell territory; only the most optimistic loggers and foilers will find joy, and even then, conditions are usually groveling at best.

April: Transition and Tactical Windows

April marks a significant drop in average swell height to 0.7 m and period to 4.1 seconds. The dominant swell direction is still NNW (23.3%), but lower-period energy from S and SSE also appears, indicating a mixed sea state. Offshore wind conditions occur 1% of the time—still very low, but the wind rose shows a slight increase in lighter speeds from the east. Onshore winds from S (10.7%), SSW (7.8%), and NW (8.7%) remain the norm. This month is a transitional limbo: the winter swell machine is winding down, and summer flatness hasn't yet arrived. Small, groveling waves are possible on the few days when the wind swings offshore and a distant low-pressure system sends a lobe of energy into the lake.
