The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you – the next 16 days for Tenby (South Beach) are a real struggle. There’s no surf worth paddling out for in the entire forecast period, and that’s a long, dry spell from now right through to the end of July. Every single window shows a score of 0, so don’t bother checking the charts for a sneaky gem.
The energy is weak as dishwater, never cracking the 100-mark on the combined swell energy (top of the range is just 45) for the first week and a half. The only time the numbers get any bigger is right at the end, from Sunday 26 July onwards, when the combined energy climbs to 138 on the 26th, 337 on the 27th, 178 on the 28th, and even 493 on the 29th. But here’s the kicker – that’s all wind swell with short periods of 6 to 8 seconds, and it’s coming in with cross or cross-onshore winds at 12 to 18 mph. The surf quality is still rated poor, and the waves are lumpy and choppy. For a sheltered beach break like Tenby, that’s a messy, blown-out mess. A beginner spot like this, with waves over 5 ft on the 27th and 29th, is too big for learners anyway, and with that wind, it’s more about kite-surfing than paddle-surfing.
Water temp is about average for the time of year, nothing weird happening there. The only glimmer is a few glassy or clean moments in the first week, but there’s no swell to ride. So, honestly, this is a blank run. It’s not unusual for the area to have quiet spells like this, but it’s a bummer. Keep an eye on the forecasts – they can change.
Rusty.
