The Lowdown
Well, grab a coffee and sit down, because I’m not gonna sugarcoat it – this is a tough stretch for Mawgan Porth. The whole 16-day window from now through the 3rd of August is a real struggle. There’s just nothing on offer that I’d call a proper surf session. Every single entry in the forecast is marked as poor surf conditions, and the numbers back that up.
We start with the 19th of July, Sunday morning. A tiny 3ft swell from the NNW with a weak 5-second period – that’s just wind chop, not a wave. The combined energy is a measly 46 (weak). Wind is SSE at 12 mph, cross-off, so the water’s clean, but there’s no power behind it. The water temp is 65°, which is a touch warmer than normal for this time of year, so at least a dip won’t be a shock.
That pattern just repeats. The 20th and 21st offer nothing. Swell heights barely crack 2ft, periods are short, energy stays in the 20s and 30s – weak. The wind flips around but never gives us a clean, solid push. On the 22nd and 23rd, we see a little bump to 3ft, but the period is still trash at 5 to 6 seconds, and the energy only reaches 81 (still weak). The wind is cross-off or cross, but it’s a moderate to fresh breeze, so the surface is lumpy.
The 24th is a complete write-off: 1.0ft and 0.3ft swells. The 25th and 26th see a bit more size – 3ft to 5ft – but the wind is cross-on or onshore from the WNW at 12 mph, making it choppy. The energy on the 26th morning finally hits 181 (moderate), but with a 7-second period and onshore wind, it’s just a messy, blown-out shorebreak. Not worth paddling out for.
The week of the 27th to the 3rd of August is more of the same. Swell heights bounce between 1ft and 4ft. Periods sit around 6 to 10 seconds. The energy values are mostly in the 60s to 90s (weak), with a couple of 108 and 102 readings (moderate) on the 29th, but that’s paired with onshore wind. The wind is almost always cross-on or on, with moderate breezes keeping things choppy.
There’s no standout. No day where the swell direction matches the optimum WNW, the wind turns offshore, and the size clicks. It’s just a long, flat, or messy run. For a spot like Mawgan Porth, a river break that’s fairly consistent, this kind of blank run is a bummer, but it happens. The forecast can always change, but right now, I’d leave the board at home and find something else to do.

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.
