Conditions at Costa Nova in June
June: Trade-Wind Slop
June is the beginning of the true summer pattern. Average swell height drops to 1.5m (5ft) and period bottoms out near 9.2s, signalling a transition from distant groundswell to locally generated NW/NNW windswell. The swell rose is dominated by NW (38.0 per cent) and NNW (25.4 per cent), with WNW (22.4 per cent) playing a secondary role. Waves are frequent but are mostly shorter-period, less powerful swell that is easily chopped up.
The offshore wind window collapses to just 14 per cent of the time. The persistent NNW flow (43.5 per cent) and NW (13.4 per cent) create cross-onshore, textured conditions for much of any given day. Still, the long daylight hours and warm air (19.1°C) make for appealing beach days, and the water is pleasant at 17.7°C. If you can find a dawn window with a light E/SE wind, there are usually fun, waist-to-chest-high runners to be had, just don't expect winter's push.
