Conditions at Hash Point in December
December: Winter's Peak at Hash Point
December is arguably the best all-round month of the year at Hash Point. Average swell height is 7ft (2.1m), average period is 12.9s, and the wind is ideal 62% of the time - the highest mark of the year. The directional radar is also friendlier than at any other month: NNW drops to 31.7%, NW is 27.9%, WNW climbs to 12.0%, and due W reaches 1.9%. That western component is small but meaningful for a WSW-facing beach, making long-period W/NW swells wrap more cleanly down the point. The wind rose shows E (13.7%), ENE (8.3%) and NNE (7.2%) combining for a reliable offshore morning flow, while NNW (16.8%) is less dominant than earlier in winter. Winter storms are at their peak, and when the NAO goes negative, the low pressure train just keeps coming. Air temp averages 17.4°C (10.9-24.4°C), water temp is 17.6°C, and daily rainfall is 1.10mm. This is the month to book the trip and leave the summer board at home.
