Conditions at Thorli in May
May: Spring Cleanup
May is when Thorli starts feeling like a surf spot again on a regular basis. Average swell height eases to 5-6ft (1.8m) with an average period of 9.1 seconds. Ideal offshore wind covers 28 percent of the month, the best ratio since the previous autumn, though a variable SE (9.5%) and SSE (8.2%) wind regime can still create cross/onshore chop. The favorable swell window is now the largest of the year so far, accounting for roughly 16 percent of the wave rose, with SE (9.6%) and ESE (4.4%) supplying most of that energy. Wave heights from the SE are mostly in the 1-2.5m (3-8ft) band, so you get clean, fun-sized surf rather than winter's slabs. SW swell (14.6%) and SSW (12.1%) remain dominant in the background, but they no longer call all the shots. Spring air warms to 5.7°C, water reaches 7.8°C, and precipitation is a lower 3.29 mm/day. This is a reliable grovel-to-fun month with rising opportunities for clean sessions.
