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 December, Cox Bay offers solid surf conditions with an average swell height of 1.8m and a well-spaced period of 12.8s, providing consistent, powerful waves. The dominant swell direction is from the WSW, contributing to the majority of quality surf, particularly in the 1.5–2.5m range, which is ideal for intermediate to advanced surfers. Wind conditions are favorable for surfing 36% of the time, with lighter winds (under 20kph) predominately from the west to northwest. However, stronger onshore easterly winds can occasionally disrupt conditions, especially at higher speeds (20–40kph). Overall, December delivers reliable, well-formed waves with decent size and power, though wind management is key—mornings often provide the cleanest sessions before winds pick up. Advanced surfers will find the best opportunities on WSW swells, while smaller days (1–1.5m) are more approachable for less experienced riders.
