April: The Autumn Window Opens Wide
By April, Jan Juc's surf season is in full gear. The average swell height pushes to 5-6ft (1.5-1.8m), and the period extends to 12.3s - squarely in the powerful long-period category. SSW and SW still supply the bulk of the energy (20.5% and 46.9%), but interestingly WSW (9.1%) and W/NW components become more prominent, showing the storm track is shifting and the swell window is broadening.
Most importantly, ideal wind conditions jump to 39%. The wind rose no longer favours the onshore SSE/SE flow; instead, NNW (10.2%), WNW (9.9%), W (8.8%) and NW (7.1%) make up a big part of the wind distribution. These directions are offshore or cross-offshore for Jan Juc, creating the clean lines this spot needs to really shine. With air temperatures at 15.6°C, water temperature dropping to 17.7°C and rainfall at 2.02mm/day, layering up is wise, but the surf quality is well worth it.
