Conditions at Portrush in June
June: Summer's Least
June's numbers underline the summer slump: average swell 3-4ft (0.9-1.2m), period 8.4s, and plenty of W and WNW energy that too often arrives as short-period, wind-affected surf rather than organised groundswell. The swell rose still shows WNW at 27.7% and W at 24.7%, but the bulk of it is in the small, fun-sized 2-5ft (0.5-1.5m) range. The wind rose is dominated by NNW at 14.7%, with NW and WNW also well represented, so clean conditions depend on early-morning E/SE offshore breezes before the sea breeze flips things onshore.
With water at 12.8°C and air at 12.6°C, summer surfing is comfortable, but consistency is not. You will be grateful for small-wave boards and low expectations.
