Rosie's Bay - surf spot statistics

Rosie’s Bay in Canada offers surfers a mix of swell and wind conditions throughout the year, with distinct seasonal patterns. The best months for surfing are typically from late autumn through early spring, particularly December, January, and February. During these months, ground swell dominates (87%), providing the most consistent and powerful waves, averaging 1.8 to 2.0 meters in size. While wind conditions are less favorable (only 33-35% of days have good winds), the strong ground swells compensate, making these months prime for experienced surfers who can handle challenging cross-shore or onshore winds. March and November are also solid, with decent ground swell presence (75-77%) and similar wave heights (1.7-1.8m), though wind quality remains inconsistent. From April onward, conditions gradually decline. Spring and summer (May to August) see weaker swells (0.9-1.4m), a higher proportion of wind swells, and fewer clean wind days (20-25%). Surfable waves still occur, but they’re smaller and less reliable. September and October mark a return to better ground swell influence (56-69%) and slightly improved wind conditions (34-36%), though wave size remains moderate (1.1-1.5m). In summary, the peak season is winter, with December to February offering the biggest and most consistent waves, while shoulder months like September-November and March-April provide decent alternatives before the summer lull.

June at Rosie’s Bay offers consistent but generally small surf, with an average swell height of 1.0m and a solid 12.1s period, providing clean, well-spaced waves. The swell is predominantly from the SSW, WSW, and W directions, with the highest frequency of rideable waves (1-2m) coming from these angles. While most waves fall in the 0.5-1.5m range, there are occasional larger sets, particularly from the W, where waves can reach up to 2.5m. Wind conditions are less favorable, with only 23% of the time offering ideal offshore or light cross-shore winds (mostly from the N to ENE). The majority of winds come from the W to NW, often blowing at 10-30kph, which can create choppy or onshore conditions. Overall, June delivers surfable waves, but patience and timing are key to scoring the best sessions when wind and swell align.
