Kincardine • Statistics for January

January: Deep-Winter Slop and Occasional Power

January is the heart of the Great Lakes storm season, and Kincardine sees its average swell height push toward 4ft (1.3m) with an average period of 5.0s. The wave rose is dominated by NNW (14.6%) and NW (11.6%) swell, with solid showings from W (8.8%) and WNW (9.1%), meaning the exposed west-northwest orientation catches a good share of the available energy. Most of that energy, however, is short-period windswell, so conditions are often lumpy and onshore. The wind tables tell the story: westerly and northwesterly winds blow straight into the beach, while the preferred offshore directions from ENE, E, ESE and SE combine for only about 12% of all wind, with just 4% actually ideal for surfing.

Arctic air keeps the average temperature at -2.9°C with precipitation of 1.89 mm/day, so expect serious cold, possible ice and a thick winter wetsuit. Water temperatures are near freezing, and the best windows come when a reinforcing high-pressure wedge pushes east or southeast wind across the lake after a strong frontal passage, momentarily cleaning up the leftover west-northwest swell. Those are the rare January sessions where 3-5ft (1-1.5m) waves can actually line up.
