The Lowdown
Alright, let’s get this straight. The next week or so is pretty grim for a wave. We’re looking at a real flat spell, and the swell that does show up is going to be messy, short-period windswell, mostly blown out by onshore and cross-onshore winds. It’s going to be a beach day, not a surf day, for a while.
The water temp at Whitesand Bay (United Kingdom) is sitting at 62°F, which is about average for this time of year. Nothing wild there.
The first week is a write-off. Tuesday the 4th has a little bit of 4ft swell but it’s coming in at a short 7 seconds and the wind is a cross-on 12 mph, so it’s just going to be a choppy mess. It stays that way through the 8th, with the swell dropping and the wind staying on it. We get a little bump on Wednesday the 6th, but it’s still no good. The weekend is flat, with nothing but dribbles. It’s a real bummer.
Then, there’s a glimmer. On the 12th, the swell starts to pick up again, but the periods are still short and the wind is cross-shore. It’s not until Thursday the 14th that things finally line up. That morning, we’ve got a 6ft swell from the W, with a 7-second period, and the wind is glassy. That’s right, glassy. The energy is moderate (341), and this is the standout of the whole run. It’s the only time the forecast says "good surf conditions."
Now, the swell is 6ft, which is a bit much for the beginners, but for the rest of us, it’s a proper wave. The direction is W, which is close to the WSW optimum for this spot, so it should be working. The glassy conditions are the key; that’s going to clean it right up. The afternoon looks a bit more marginal as the wind switches light cross-on, but the morning session is the one to chase.
After that, it fades again. The 15th and 16th have some small, clean waves, but they’re tiny. The 17th and 18th see a pulse of 5-5ft swell, but the wind is howling from the north, cross-shore, which will make it lumpy and hard to surf. That’s more of a wind sport day.
Looking a bit further out, the 19th has a bigger swell, 8ft in the afternoon, and the energy is strong (511), but the winds are onshore and it’s a short-period swell. For a beach break, that’s going to be a close-out. It’s expert only, and even then, it might be a mess. It’s a promising sign for the future, but it’s not the one for this window.
So, the call is simple: Thursday the 14th, early. That’s the window. Be there.
