Bore - surf spot statistics

Bore, Norway, offers surfable waves year-round, but conditions vary significantly by season. The best months for surfing are typically from September through February, when swell size and consistency are at their peak. During this period, mean swell sizes range from 1.4m to 2.1m, with ground swell playing a more significant role compared to wind swell—especially in January, February, and December, where ground swell contribution reaches 25-29%. However, wind conditions remain challenging, with an average of 86-88% unfavorable winds, limiting ideal surf days. The autumn months (September-November) provide a good balance of swell size (1.4-1.8m) and slightly lower wind swell dominance, though clean offshore winds remain rare. From March onwards, swell size decreases steadily, hitting the lowest point in June-August (0.9-1.0m), where wind swell dominates (73-78%) and ground swell nearly disappears (4-6%). Summer months (June-August) are the least favorable due to small waves and persistent onshore winds (90-91% bad conditions). While winter offers the biggest waves, surfers must contend with harsh winds and cold, making shoulder seasons like September-October a pragmatic choice for those seeking more manageable conditions.

In May, Bore offers surfable conditions with an average swell height of 1.0m and a decent period of 7.7s, providing consistent but generally small waves. The swell direction is predominantly from the WNW and NW, contributing to 12-13% of waves in the 1-1.5m range, with occasional larger sets (1.5-2m) making up around 2-4% of the time. Small waves (0.5-1m) are most frequent, making it ideal for beginners or longboarding. Wind conditions are less favorable, with only 12% of winds being ideal for surfing—typically light offshore or cross-offshore from the east or northeast. However, stronger onshore winds from the south and southwest (10-30kph) occur frequently, creating choppy conditions. Surfers should target sessions during WNW/NW swells paired with lighter easterly winds for the best experience. Overall, May delivers rideable waves but requires patience for optimal wind alignment.
