Conditions at Manly in January
January: Peak Summer Offshore Flow
January is one of the most reliable months for clean, rideable surf at Manly. The average swell stands at 5ft (1.6m) with an 8.4s period, and ideal offshore flow is present 46% of the time. The waverose is dominated by ENE, E and SSE energy, with most waves in the 1-2m (3-6ft) band. That is not the preferred SW/W direction for this west-facing beach, so much of the swell is short-period windswell and refracted easterly energy. Still, under the dominant NE/ENE offshore winds, the surface stays clean and the beach breaks offer punchy, fun waves. With air temperatures around 23°C and water temperature at 23°C, it is classic shirtless summer surfing - just watch the afternoon NE seabreeze for a bump in texture.
