Conditions at Baltrum in June
June: Summer Stalemate and Summer Flat Spells
Baltrum settles into its summer pattern: the Atlantic is quiet, and the North Sea only sees waves when the wind creates them. The average swell height stays at 1.0m (3.3ft), with a period of 5.8s and a day-to-day consistency that drops significantly. The dominant swell direction is a resounding NNW (27.4% of the wave rose) - again pointing directly at the beach's exposure - but this energy is now sourced locally from wind, not the open Atlantic. The wind is a 50/50 mix of offshore (S-SW) and onshore (NW-NNW) directions. The ideal wind frequency is a low 10%, but the smaller size means the onshore winds are less likely to completely detonate the waves - they just make the already short period more chaotic. Water temps rise to a warm 15.2°C, and air temps can hit 29.5°C. You might get some clean, waist-high shoulders if a mild S wind blows against the NNW windswell, but do not plan a surf trip around it. This is the month for kitesurfing and long summer cruises, not challenging surf.
