Borkum seasonal overview
Best Surf Season (October - March)
During these months, the North Atlantic storm track is fully active, sending consistent, moderate to large swell into the North Sea. Borkum's NNW exposure means it's perfectly aligned to capture the most powerful NW-NNW swell trains. Average wave heights hover around 1.0-1.3m, often reaching 1.5-2.5m during peak events, providing 'pumping' to 'firing' conditions. Wave periods average 6.3-6.5s, but long-period swells (>10s) become more common, delivering substantial power. Crucially, the wind regime shifts: high-pressure over continental Europe and lows tracking north allow frequent southerly to southwesterly winds (SSW-SW), which blow directly offshore at Borkum. This creates clean, groomed waves. The ideal wind percentage peaks at 11-13% in October through January, but the raw volume of swell ensures plenty of rideable days, even if not perfectly clean. This is prime time for Borkum.
Fair Surf Season (April & September)
These are transitional months. In April, the North Atlantic is still moderately active, and you can find overhead swell from NNW-NW, but the average wave height drops to 0.8m. The wind is tricky: spring brings more variable winds, with higher frequencies of onshore north-northeast winds. September sees a resurgence: average swell height climbs back to 1.0m, and ideal wind windows start to open again (11%). While not as consistent as winter, these months offer a decent shot at clean, fun-sized waves, especially during the occasional early autumn low.
Low Surf Season (May - August)
Summer is the quietest period for Borkum. The North Atlantic storm track weakens, resulting in average swell heights of only 0.8m and short periods (5.3-5.6s). The dominant swell direction is still NNW-NW, but most of it is under 1m, often only 'small' or 'micro'. Additionally, the prevailing wind pattern becomes northerly to northeasterly, which is directly onshore for this north-facing beach. The ideal wind percentage bottoms out at 8-9%. You'll find many days with choppy, messy waves and occasional small, clean waves if a south wind sets up. It's a good time for longboards and funboards, but serious surfers usually look elsewhere or take a break.

Conditions at Borkum in May
May: Summer Lull Sets In
May ushers in the summer lull with an average swell height of 0.8m and short period of 5.6s. Swell is dominated by NNW (29.3%) and NW (11.5%), but the vast majority is under 1m—small and weak. Wind patterns shift further: N (7.1%), NE (8.2%) and ENE (8.8%) bring onshore flow, while offshore directions like SSW (4.6%) and SW (6.9%) are less frequent. Ideal wind remains at 8%. Expect mostly choppy, micro conditions. When a rare south wind coincides with a leftover swell, you might find some clean, groveling waves on a longboard, but consistency is low.
