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.

June at this surf spot in Bore offers inconsistent but occasionally surfable conditions. The average swell height is 0.9m with a 7.0s period, providing weak to moderate energy. The most common swell directions are from the NW and WNW, contributing to the majority of waves in the 0.5-1.5m range, with occasional larger sets (1.5-2.5m) making up around 5-6% of conditions. Smaller, weaker waves (0-0.5m) are frequent, limiting surf potential. Wind is a key factor—only 10% of the time is it ideal for surfing, with the worst conditions coming from NNW, where strong winds (20-50+ kph) are common, creating choppy or blown-out surf. ESE to SSE winds occasionally provide lighter offshore or cross-shore conditions, but they’re rare. Expect mostly small, sectiony waves with wind challenges, making it a hit-or-miss month best suited for flexible surfers or those content with softer days.
