That means Inches can see repeated sets of clean, chest-high waves when the wind comes from the N/NW. ENE wind remains dominant at 44.5 percent, but NE jumps to 16.6 percent and the N/NNW quadrant contributes 2.5 percent, enough to create frequent offshore windows. Water temp cools to 27.3°C, air average sits at 24.1°C, and rainfall eases to 2.6 mm/day. December is one of the best bets all year for consistent, rideable surf at this south-facing beach.
