Conditions at Thorli in November
November: Storm Season Builds
By November the Icelandic low is fully active, and Thorli enters its high-performance winter window. Average swell height rises to 9-10ft (2.9m) with a period of 10.4 seconds, and the Atlantic produces serious, powerful groundswell with increasing frequency. The tradeoff is a messy wind regime: ideal offshore flow is only 13 percent, while NNE (12.6%), NE (11.7%) and NNW (9.9%) dominate. ENE (7.0%) and ESE (7.1%) add more onshore energy. The favorable NE-ENE-E-ESE-SE swell window is about 10 percent of the wave rose, with SE (4.7%), ESE (2.6%) and E (1.1%) leading; those eastern pulses sit mostly in the 1.5-2.5m (5-8ft) range and are often a good deal more powerful than the raw numbers suggest. SW (8.3%), SSW (7.1%) and WSW (5.8%) dominate the background wave rose, as the Atlantic steers most of its giant energy toward Iceland from the south. But a single strong high-pressure cell to the north can flip the local wind northwest/offshore and turn November into a heavy, pumping Thorli. Air temps hover around 0.5°C, water cools to 7.1°C, and precipitation averages 5.05 mm/day.
