Conditions at Seinesodden in June
June: Peak Lull and Onshore Winds
June is the weakest month of the year at Seinesodden, along with July. The average swell height is only 2-3ft (0.8m) and the period is 8.0 seconds, a recipe for short-period, locally wind-driven surf. Although the waverose still shows WSW at 21.4%, W at 20.6%, NNW at 18.3% and WNW at 12.3%, most of this is under 1m and lacks the punch of winter groundswell. The wind distribution turns harsh: NNW at 13.5%, NNE at 12.5%, WSW at 10.2% and SW at 10.1%, while the offshore E/ESE/SE/SSE block collapses to just 13.2%. Only 16% of the time does the wind blow in an ideal direction for clean surf. With long daylight and air temperatures averaging 7.3°C, the coast is beautiful, but surf quality is mostly small and bumpy. Precipitation is 4.03 mm/day and water temperature warms to 9.5°C.
