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 August, Bore, Norway offers generally small but surfable conditions with an average swell height of 1.0m and a moderate 7.0s period. The dominant swell directions are W, WNW, and NW, with WNW swells contributing the most frequently to rideable waves in the 0.5-2.5m range, particularly between 1-1.5m. However, larger swells (over 2m) are rare, occurring only about 5-10% of the time from SW to NW directions. Wind conditions are often challenging, with only 10% of days providing ideal offshore or light cross-shore winds (typically from the E to NNE). Stronger winds (20-30kph+) are common from the NW, NNW, and S, which can create choppy or messy conditions. Surfers should target days with WNW-NW swells paired with lighter NNE-E winds for the cleanest waves, though size and consistency remain limited. Expect mostly small, playful surf with occasional mid-sized peaks when conditions align.
