Cox Bay - surf spot statistics

Cox Bay in Canada is known for its consistent surf, especially during the winter months when ground swells dominate. The best months for surfing are typically from November to February, with December and January standing out as the peak season. During these months, ground swell percentages are highest (85-86%), and mean swell sizes reach 1.7-1.8m, providing powerful and well-formed waves. While wind conditions are less favorable (only 35-37% good winds), the strong swell energy compensates, making it a prime time for experienced surfers. March and October also offer decent conditions, with good ground swell presence (73-74% and 65%, respectively) and manageable swell sizes (1.6-1.7m in March, 1.4m in October). Wind conditions remain suboptimal but improve slightly compared to mid-winter. From April onward, ground swells decline, and wind swells become more prevalent, resulting in smaller, less consistent waves. The summer months (May to August) are the least favorable, with low ground swell percentages (43-57%), smaller wave heights (0.8-1.0m), and poor wind conditions (only 17-25% good winds). September marks the transition back toward better surf, though conditions remain inconsistent until late autumn. For the best balance of swell size, consistency, and acceptable wind conditions, late autumn through early winter (October to February) is the optimal window. Advanced surfers will prioritize the winter months despite the challenging winds, while intermediate surfers might find more manageable conditions in the shoulder seasons (March and October).

In January, Cox Bay offers consistent surf with an average swell height of 1.8m and a solid period of 13.0s, providing well-organized, powerful waves ideal for experienced surfers. The dominant swell direction is from the SW to WSW, contributing to the majority of rideable waves, particularly in the 1.5–2.5m range. WSW swells are the most frequent and powerful, often producing quality waves with good shape and energy. Wind conditions are favorable for surfing 35% of the time, typically when light to moderate offshore or cross-shore winds prevail. Strong onshore winds (20–50kph) from the E to SE can occasionally degrade conditions, but the spot handles swell well due to its exposure. Overall, January delivers reliable, punchy waves suited for intermediate to advanced surfers, with the best sessions occurring during WSW swells and lighter winds.
