The Lowdown

Right then, let’s have a look at what’s on the cards for Mawgan Porth. I’ll be straight with you—this is a tough run. The first week and a half is mostly a write-off. We’ve got a lot of onshore and cross-onshore winds, and the swell is messy. The energy is weak to moderate at best, with combined swell energy readings sitting between 98 and 402 (moderate). The water temperature is about average for this time of year, nothing unusual.

The first real glimmer of hope doesn’t arrive until Saturday the 5th of September. It’s a standout morning, with glassy conditions, a light ESE breeze at 3 mph, and a clean 4ft swell from the west with a 10-second period. The combined energy is 228 (moderate). It’s small, but it’s the cleanest we’ll see for a while. That’s the time to get out if you’re desperate for a paddle.

After that, it drops right off. Sunday the 6th has clean cross-off winds but the swell is tiny, only 2ft. The energy is weak at 64. Not worth suiting up.

We then hit a gap of several days with poor conditions. Monday the 7th has a bit of size (4ft to 6ft) with a long 12-second period, but the wind is onshore. The energy jumps to 476 and 669 (moderate), but the wind kills it. Tuesday the 8th sees a big jump in size to 8ft, combined energy 1083 (strong), but it’s choppy with cross-onshore winds. That’s too big for beginners and ugly for everyone else. Wednesday the 9th is a mess: 8ft swell, strong cross-shore winds at 25 mph, energy 1129 (strong). This is more kite-surfing territory than paddle surfing.

The next true standout comes much later, on Monday the 14th of September. The morning is clean with offshore winds from the east at 12 mph, and the swell is 4ft from the west with a very long 12-second period. The combined energy is 400 (moderate). The afternoon is even better: light offshore breeze, clean, 4ft, 12-second period. This is a groundswell, and it’s going to be clean, well-shaped, with long gaps between sets. The river mouth (Mawgan Porth) should handle that period well.

Tuesday the 15th of September also has a good morning: clean, light cross-off winds, 4ft swell, 12-second period, energy 344 (moderate). That’s a solid session, but the afternoon gets blown out by a strong cross-off.

So, looking at the whole 16 days, the best on offer is that Monday the 14th of September morning and afternoon. It’s the only day with a genuine “expect good surf conditions” call. The Saturday the 5th morning is a close second for the glassy conditions, but it’s smaller. The long-range call for the 14th is promising but less certain—keep an eye on it.

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.
