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.

March at Bore offers surfable conditions with an average swell height of 1.6m and a decent period of 9.0s, providing consistent, well-shaped waves. The dominant swell directions are from the W to NW quadrant, with a notable portion of waves in the 1-2.5m range, indicating a mix of manageable and powerful surf. WSW to NW swells contribute most to the surfable conditions, especially in the 1.5-2.5m range, where waves are frequent and well-organized. However, wind conditions are less favorable overall—only 14% of the time do winds align ideally for surfing (typically light offshore or cross-shore). Stronger onshore winds (SSE to SW) are common, which can degrade wave quality, especially when paired with larger swells. Surfers should target days with lighter winds from the N to E, which coincide with cleaner conditions, particularly when swells from the W or NW are present. Expect a mix of small, playful days and more powerful sessions, but wind will often be the limiting factor.
