June: Summer Stability and Westerly Windswell

June settles into the summer pattern. The average swell height stays around 2-3ft (0.8m), and average period drops to 7.1s, meaning Newgale is living on short-period Atlantic swell and sea breeze windswell. The westerly swell window expands to its most dominant spread of the year: WSW accounts for 35.8 percent, SW for 17.4 percent and W for 11.4 percent, so the swell direction is ideal, but the energy is small. Onshore winds start to ramp up, with SSW-SW-WSW-W directions blowing about 39 percent of the time, and ideal offshore winds falling to 8 percent. The summer sea breeze often kicks in during the afternoon, adding bumps to an already modest wave. Water temperature climbs to 14.4°C, air temps average 13.4°C, and precipitation runs at 2.72 mm/day, so the wetsuit gets thinner, but surf quality takes a definite step backward. Look for early mornings with a light easterly flow and a pulse of old groundswell for the best June windows.
