The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the Portreath Beach stretch. I've got the whole 16-day picture in front of me, and I gotta be straight with you – it's a tough watch for the most part.
We kick off looking at Friday the 31st of July, and right through to the end of the second week of August, the conditions are flagged as poor. There's a real dry spell here. The only sniff of a decent wave energy spike comes around Monday the 3rd of August, where the combined energy hits 107, but it's cross-on and messy. Then again, a stronger pulse shows up on the 5th of August with combined energy over 330, but the wind is cross or cross-on and the period is short at 7 seconds, making for a chop fest. Not what any of us want.
The one thing that catches my eye, way out in the forecast, is Sunday the 9th of August. We see a big jump in combined energy to a whopping 1099 with a swell height of 8.2ft. That is serious power, but – and it's a big but – it's straight onshore with a moderate breeze from the NNW. For a beach break like Portreath, that setup looks more interesting for kite surfing than paddle surfing. It's an expert-only situation if you even try it. The swell is from the W with a 9-second period, so it's not the cleanest groundswell either.
Looking at the longer run, the 11th of August morning gives us a glimmer of hope. The wind swings to the SSW, giving us a cross-off breeze, and the swell is a manageable 3.3ft from the WSW with a 7-second period. The combined energy is 182, so there's some push, but it's still marked as poor surf conditions. Honestly, for the whole 16-day window, there’s no standout day where everything lines up. The water temp is sitting at 65.3°, which is a touch warmer than normal for this time of year, but that doesn't help the surf.
Keep the board waxed and the eye on the horizon, but this run looks like a blank one for Portreath. Forecasts can change, but for now, we're waiting.

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.
