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 February, Bore offers surfable conditions with an average swell height of 1.9m and a solid period of 9.5s, providing decent energy for quality waves. The swell direction is predominantly from the W, WNW, and SW, with the largest waves (2m+) most likely coming from the SW, WSW, and W directions. The WNW swells are frequent but tend to produce smaller waves, while the SW and WSW contributions bring more substantial wave heights, particularly in the 1.5-2.5m range. Wind conditions are less favorable, with only 14% of the time offering ideal offshore or light cross-shore winds for surfing. The most common winds come from the S, SSE, and SE, often blowing at 10-30kph, which can create choppy or onshore conditions. Stronger winds (30-50kph) are frequent from the ESE and SE, further reducing surf quality. Surfers should watch for days with lighter W, WNW, or NNW winds for cleaner waves. Overall, while the swell is consistent, wind interference limits optimal surfing opportunities, making it a spot requiring patience and timing for the best sessions.
