Conditions at Hermanus in November
November: The Trade Wind Monopoly
November slides further into summer conditions, with ideal wind at just 14% and average swell easing to 2.3m (7.5ft) with a shorter 11.2s period. Onshore ESE (17.3%), E (14.3%), SE (11.2%) and SSE (8.1%) winds dominate, often blowing 20-40kph and putting a bump on the surface. The swell rose still shows a lot of deep-ocean energy-SW at 25.6%, SSW at 17.3% and S at 9.3%-so the ocean is not flat, but clean conditions are hard to come by. A late-season cool front can still swing the wind to the NW/WNW quadrant for a day or two, and those days are the ones to circle on the calendar. Water temp warms to 17.6°C and the air feels spring-like at 17.6°C, but the surf demeanor is definitely more 'summer slop' than winter perfection.
