The Lowdown

Alright, this is Rusty, and I’m lookin’ at what we’ve got for the next couple of weeks. I gotta be straight with you – it’s a rough stretch. The forecast is a long, dry spell with hardly any surf worth paddling out for. The first real chance of a wave doesn’t show up until Thursday the 10th, and even then, it’s not looking good.

We’ve got a solid gap of nothing worthwhile from now until the 10th. On Thursday the 10th, the swell does kick up a bit, hitting 7 ft out of the SW, but the wind is a howling onshore 25 mph from the SSW. That’s not surf, that’s a washing machine. The combined wave energy is moderate at 337, but it’s all blown out.

After that, the swell drops off and the wind stays messy. Saturday the 12th shows some 6 ft SW swell, but again, it’s onshore and choppy. There’s a little moment on Sunday the 13th afternoon when the wind goes glassy, but the swell is tiny at 2 ft. It’s clean, but there’s nothing to ride.

From the 14th onward, it’s a dead zone. The swell is down to 0.3 ft for days on end, with only a few brief windows of clean, glassy conditions on the 20th, but with zero energy. The water temperature is a touch warmer than normal at 64°F for the time of year, but that’s the only good news.

Honestly, there’s nothing here to get excited about. The only break in the forecast is Fishermans (Rhiw), a reef break that’s fairly consistent, but it’s not doing anything for us. The setup is a reef, but with the swell direction and bad wind, it’s a no-go. Don’t bother paddling out; you’d be better off with a kite if the wind ever cleaned up, but it doesn’t.

This is a real blank run for the area. Sometimes the forecasts change, but right now, it’s a long wait for a wave.

Rusty.

A general guide to surfing at Fishermans (Rhiw) can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Fishermans (Rhiw) may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
