Bunkers - surf spot statistics

Best Surf Season (October - March)

The North Atlantic winter machine kicks into high gear from October through March, delivering the most consistent and powerful surf to Bunkers. Average swell heights range from 1.8m to 2.1m, with periods often in the 7-8 second range – punchy, rideable, and occasionally reaching longer period windows when strong extratropical storms march east. The west-northwest facing beach lines up perfectly with the dominant W to NW swell trains, and when high pressure sets up over Scandinavia, offshore winds from the E through SSE quadrant glass off the faces. Ideal wind percentages hover near 20%, making this the go-to window for quality sessions. The NAO index often amplifies the storm track, so keep an eye on negative phases for blocking highs that may steer depressions further south.

Fair Surf Season (April & September)

These transitional months offer a mixed bag. In April, the ocean begins to quiet down – average swell drops to 1.2m and periods shorten to 6.6s, but the wind still cooperates about 19% of the time. Swell directions remain favorable with WNW and NW dominating, though the energy is more inconsistent. September sees a ramp-up as autumn approaches, with average heights of 1.5m and periods of 6.6s, plus a similar 19% favorable wind window. Both months can produce clean, fun-sized waves when a low pressure system brushes the region, but don't count on long-period groundswells just yet.

Low Surf Season (May - August)

Summer months are the leanest for consistent surf at Bunkers. Average swell heights plateau around 1.1–1.2m and periods dip to 5.8–6.1s, resulting in weaker, wind-swell dominated conditions. Although the WNW and NW directions still contribute the bulk of the swell, the energy is often too small for much more than groveling. Offshore wind frequencies drop to 12-16%, with onshore westerlies prevailing during this period. While the occasional summer cold front can provide a brief pulse of 1.5m+ waves, the overall signal is quiet. This is the time to focus on log sessions or travel elsewhere for your fix.

January: The North Atlantic Roars

January is the peak of winter in the North Atlantic, and Bunkers feels the full brunt. Average swell height hits 2.1m with an average period of 7.5s – solidly in the 'punchy' to 'powerful' range. The dominant swell directions are WNW (9.1%) and W (8.8%), both squarely in the optimal window for this west-northwest-facing beach. Swell from WSW and NW also contributes heavily. Wave heights in the 1.5–2.5m range are most common, with a significant portion exceeding 2.5m – ideal for experienced surfers. Wind conditions are less cooperative: favorable offshore winds from E, ESE, SE, SSE account for only about 18% of the time, while onshore westerlies (WSW, W, WNW) dominate over 30% of the time. When the wind does align, expect glassy, powerful lines off the North Sea. However, the short average period indicates most swell is windswell or locally generated, so long-period groundswell events are less frequent but still possible when deep lows stall near Iceland.
