The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Alright, I gotta be straight with you – this outlook is a bit of a bummer. We’ve got a long stretch of pretty ordinary conditions ahead. The first real chance of a wave doesn’t actually show up until Monday morning, August 3rd, and even then it’s not much to write home about. We’re looking at a gap of several days with no real recommendations after that.
So, let’s start with that Monday morning. Portreath Beach is the only game in town. We’ve got a small 3ft swell rollin’ in from the WSW with a 9-second period. The energy is moderate, just cracking 106, but the wind is a light offshore from the SSE, so it’ll be clean. The water temp is about average for the time of year. It’s surfable, but it’s very ordinary. The winds shift to a cross-off in the afternoon, but the swell drops to 3ft and the energy weakens. Honestly, it’s a session for a longboard and low expectations.
Tuesday, August 4th, the wind cranks up from the SW at 18-22 mph and the swell only gets a bit bigger, but it’s messy cross-shore wind. The energy picks up to 228, but it’s a poor, lumpy mess. Not worth it.
Wednesday, August 5th, the swell gets a bit more size, 7ft in the morning from the W, and the energy hits a strong 576, but it’s a fresh cross-onshore wind. That’s a big, blown-out, lumpy mess. For the experienced crew, it’s a battle, but for the average punter, stay on the sand.
Thursday, August 6th, the wind swings onshore from the NW, dropping the swell to 5ft, and the energy is moderate at 163. The conditions are poor, and it’s a bit of a mystery.
Then we hit a real flat spell. From Friday, August 7th, all the way through to the morning of Tuesday, August 12th, the swell is tiny, often under 2ft. The energy is weak, barely hitting 30 or 40. There’s a few mornings with clean light offshore winds, but there’s no wave to ride. It’s a week of flat calm.
The best of the whole outlook, if you can call it that, is the morning of Wednesday, August 12th. The wind is a fresh offshore from the ESE, and the swell has bumped up to 5ft. The energy is a solid 212. The catch is the swell direction is from the N, with a short 6-second period. It’s a clean wave, but that short period means it’ll be a bit soft and fat. The afternoon session is a bit cleaner with a moderate offshore wind, but the swell drops to 5ft. This is the one standout, but it’s for intermediates and above, not for beginners.
After that, it’s back to the doldrums. From Thursday, August 13th, right through to the end of the forecast on Tuesday, August 18th, the swell is tiny, the wind is mostly onshore or cross-onshore, and the energy is weak. The wave states are described as “unknown” or “choppy,” which is never a good sign.
Bottom line: if you’ve got a longboard and low expectations, the morning of Monday, August 3rd, or the morning of Wednesday, August 12th, might give you a wobbly one. Otherwise, it’s a good time to wash the wetsuit and check the forecast again in a week.

Information about the Portreath Beach Surf forecast
The above surf forecast table for Portreath Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Portreath Beach can be found by selecting the local surf guide option on the grey menu. Our Portreath Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Portreath Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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 Portreath Beach 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.
