The wind rose now shows the summer pattern stirring: NNW at 13.9%, NW at 8.8%, and NE/NNE totals growing. Air and water warm to 19.7°C and 21.2°C respectively, and rainfall is minimal. Surfing is still possible most days, especially on the dawn push, but the long clean rides of winter become less dependable.
