Conditions at Yoff Beach in September
September: The Perfect Storm of Conditions
September is arguably the sweetest month for surf at Yoff Beach. Ideal wind remains high at 42%, with the monsoon flow still providing S-SW-W offshore breezes. At the same time, the North Atlantic begins to reawaken - average swell nudges up to 4-5ft (1.2-1.5m) and period extends to 10.1s. The direction is a mix of NW (35.1%) and NNW (35.2%), with a healthy 14.5% from WNW. Most importantly, the distribution shows more energy in the 5-6.5ft (1.5-2m) range: 6.2% of NW and 10.0% of NNW produce head-high+ sets.
So you get the cleanliness of the summer with the first hints of proper swell. It's enough to make Yoff's banks light up. Water temp is at its warmest, 28.7°C, air around 27.7°C, and precipitation is still significant at 4.38mm/day - trade that in for the glassy conditions under the storm fronts. September is prime time for the casual surfer and the core charger alike.
