Conditions at Hanstholm in October
October: The Machine Comes Online
The North Atlantic roars to life in October, and Hanstholm feels it. Average swell height jumps to around 5-6ft (1.5-1.8m) at 1.7m, period to 6.7s, and the number of deep low-pressure systems crossing the Norwegian Sea increases sharply. This is due to the climatological strengthening of the North Atlantic storm track and, in many years, a more positive NAO pattern that funnels relentless west to northwest wind and swell toward Denmark. The swell distribution is still weighted toward W/WSW/WNW, but the more favorable N/NNE/NW/NNW window totals only about 7%. Wind is the key ingredient: W/WNW/WSW winds dominate, and favorable offshore S to SE winds are only present 9% of the time. When a deep low sits just west of Denmark and a transient high moves over southern Scandinavia, Hanstholm can be nothing short of epic: 6-8ft (1.8-2.4m) of lined-up NW groundswell stacking on an offshore SSE wind. Those windows are rare but increasingly common in October. Water temperature has dropped to 12.7°C, so it is time to swap back to a 4/3mm or hooded 5/4mm as the season progresses.
