The Lowdown
Alright, Rusty here again. Let’s get this straight: the next 16 days at Mawgan Porth are a total bust. From now, Sunday the 19th of July, right through to the end of the month, there’s nothing worth paddling out for. The swell is tiny, mostly under 3 feet, with weak energy figures (mostly under 100). The winds are a mess – cross-shore, cross-on, or onshore – meaning the waves are choppy, lumpy, or blown out. Even when a pulse of swell hits on the 28th of July, with 6ft to 7ft from the north and moderate to strong energy (684 and 598), the wind is a strong cross-on, making it a churned-up mess. For a river break, that’s a kite surfer’s playground, not a paddle surfer’s. The water temperature is about average for the time of year, nothing unusual.
The closest thing to a highlight is the morning of the 31st of July. That Friday morning, the wind goes clean cross-off from the ESE at 22 mph, with a 3ft swell from the WNW at 6 seconds (short period). The energy is still weak (98), but it’s the only clean window. The afternoon has a bit more size at 4ft, but the wind is a strong breeze. That’s your best bet, and it’s not a great one. For the rest of the time, it’s a long, empty gap. A blank run like this is pretty normal for this area when the conditions don’t line up. Forecasts can change, so keep watching, but for now, I’d leave the board at home.
Rusty.

Information about the Mawgan Porth Surf forecast
The above surf forecast table for Mawgan Porth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Mawgan Porth can be found by selecting the local surf guide option on the grey menu. Our Mawgan Porth 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 (Mawgan Porth) 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 Mawgan Porth 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.
