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.

December: The Deep Winter Engine

December ties with January for the highest average swell height at 1.3 m, with a period of 5.1 seconds. Swell directions are well-mixed, but W (10.8%) and NW (10.7%) are dominant, both excellent for the beach. Offshore wind conditions are at 4%. Onshore winds are brutal: WSW (10.8%), W (10.5%), and WNW (7.9%) combine for nearly 30% of all wind observations, often accompanied by strong speeds 20–40 kph. The lake is a churning cauldron of whitecaps most days. However, the occasional arctic high-pressure system can park over the region, bringing crystal-clear skies and light east-northeast winds. Those days can produce some of the best waves of the year: solid, powerful walls rolling in with minimal chop. December is the true peak of the Lake Huron winter, demanding respect and offering rare moments of glory.
