The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Mawgan Porth for the next couple of weeks. Gotta be straight with you – we’re in for a proper quiet spell. The wind is all over the shop, and the swell just isn’t cooperating.
The water is sitting at 64°, which is a touch warmer than normal for this time of year – a nice little bonus if you do get in, but you’ll need a lot more than that to make it worthwhile.
Mawgan Porth (river) – the only break on the map here.
For the first few days, it’s a no-go. Saturday the 18th and Sunday the 19th are a write-off; we’re looking at tiny waves (2ft from the north) with a stiff onshore or cross breeze, giving us nothing but chop. The combined wave energy is weak (37). Not worth paddling out.
Monday the 20th and Tuesday the 21st offer a little glimmer, but it’s marginal. Tuesday morning the 21st is the best of a bad bunch early on – we get a glassy surface with the wind dropping right off to nearly nothing, and the swell is 3ft from the NNW. The energy is still pretty weak though (76). It’s surfable, but very ordinary. You might get a few knee-high rollers if you’re desperate.
From Wednesday the 22nd through to Saturday the 26th of July, the swell tries to pick up, but it’s all onshore wind from the west and northwest. By Sunday the 26th, the swell height reaches 6ft from the west (energy 358), but it’s blown out by a fresh onshore breeze. For a river break, that’s just messy. This setup looks more interesting for kite surfing than paddle surfing, honestly.
The following week doesn’t give us much either. Monday the 27th through Thursday the 30th keep showing onshore winds and lumpy conditions. The swell holds around 4ft to 5ft, but the wind never cleans it up.
We get a slight shift on Friday the 31st of July and Saturday the 1st of August, with the wind turning cross-offshore from the NE. The swell sits around 5ft from the WNW, and it’ll be clean on the surface. The energy is moderate (217-250). It’s the closest we get to a decent window, but the waves are still pretty average for a spot like this.
The best offer in the whole run, and I mean the only real standout, is Sunday morning the 2nd of August. We get a clean, offshore breeze from the ENE and a small, longer-period swell of 2ft from the west, with an 8-second period. The energy is very low (59), so it’s not going to be big, but the wind is offshore and conditions will be glassy. If you’ve got a log, it might be your only chance for a few clean little peelers.
Honestly, it’s a tough outlook. There’s a long gap of poor conditions right through until the very end. Keep an eye on it, because forecasts can change, but right now, I’d leave the board in the car for a while.
Rusty.

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.
