The Lowdown
Alright, let’s be real. The outlook for the next couple of weeks is a total bust. There’s a massive gap with no decent waves at all, from now through the end of the month. The only spot we’ve got is Fishermans (Rhiw), a reef break that usually can hold a bit of swell, but it’s dead flat.
From Wednesday 15th July to Thursday 30th July, we’re looking at ankle-slappers – 0.3ft to 0.7ft of nothing. The combined swell energy is pathetic, barely registering (6 to 12), and most days it’s sitting at zero. Swell direction is from the W or SW, but it doesn't matter when there’s no height. Water temp is about average for the season.
The first week is a total washout. Thursday 16th July morning is glassy and calm, but the waves are only 0.3ft – it’s a pond. The weekend of the 18th and 19th is even worse, with a moderate breeze and zero energy. The second week doesn’t improve. Even a glassy morning on the 24th only brings a tiny 0.3ft ripple.
The one faint glimmer is Thursday 30th July morning, with a light rain shower and a 0.7ft bump from the WSW, but the wind is a fresh 19 mph onshore, making it choppy and ugly. That’s kite territory, not surf territory.
It’s just a flat spell. Forecasts can change, but right now, this is a dead run for the area. Keep the wax in the wrapper.
