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).

November at Cox Bay offers solid surf conditions with an average swell height of 1.7m and a decent period of 12.1s, producing well-spaced, powerful waves. The swell is predominantly WSW (15.66% of waves in the 1-1.5m range), providing consistent, quality surf with good energy. SW and S swells also contribute, though less frequently. Wind conditions are favorable for surfing 33% of the time, with the most common offshore or light winds coming from the NE to E quadrant, particularly ENE and E directions. However, stronger onshore winds from the SE to SW can occasionally degrade conditions, especially when speeds exceed 20kph. The wave distribution shows that surfers can expect rideable waves (1-2.5m) frequently, with the sweet spot being WSW swells in the 1.5-2m range (11.19%). Overall, November delivers reliable, mid-sized surf with periods of excellent conditions when winds align, though it’s worth monitoring for those occasional onshore days.
