Conditions at Thorli in April

April: Spring's Window Opens

April marks a real shift in the quality equation at Thorli. Average swell height drops to 7-8ft (2.4m) and the period settles to 9.7 seconds, but the wind patterns become friendlier: ideal offshore flow jumps to 21 percent of the time. The dominant wind directions are no longer overwhelmingly onshore; NNE (8.5%), NNW (9.0%), ESE (8.2%) and SE (8.4%) all share the spectrum. The favorable swell window expands to about 13 percent of the wave rose, led by SE (6.9%) and ESE (3.4%). These easterly pulses arrive mostly in the 1-2.5m (3-8ft) range, offering fun, rippable waves that can still hold plenty of punch. SW swell (12.1%) is still present, but the increasing southeast component means Thorli starts to wake up from its winter onshore gloom. Air temperatures rise to 2.4°C, water temperatures have warmed to 6.2°C, and precipitation drops to 3.76 mm/day, making April a much more workable month.
