The Lowdown

Alright folks, Rusty here. Let's have a look at what Mawgan Porth has in store for us for the next couple of weeks.

Honestly, it's a tough spell ahead. The whole 16-day window is pretty much a write-off for decent surf. There are no good options on the table. Every single session flagged shows "poor surf conditions," and it’s not just a day or two—this looks like a prolonged blank run that's more normal for the area when the weather patterns lock in. We're looking at a solid two weeks of onshore winds, lumpy chop, and blown-out waves.

Right off the bat, Tuesday the 25th sees a small 2ft west swell with a 10-second period, but a moderate SE breeze makes it a messy cross-off. The combined swell energy is a weak 92, and this pattern just repeats day after day. The water is sitting at 65°, which is a touch warmer than normal for this time of year. Wednesday the 26th and Thursday the 27th are much the same—tiny, weak, and messy.

Things get a bit more energetic starting Friday the 28th, with the combined energy hitting a moderate 139 by morning, but that 3ft southwest swell is under a cross-onshore wind, making it choppy. By Saturday the 29th, the swell jumps to 6ft with 325 energy, but it's under a fresh 18 mph cross-onshore and a risk of thunderstorms, so the quality is shot.

Sunday the 30th offers the biggest energy of this early period at 476, with a 5ft west-northwest swell and a 10-second period. But again, the wind is all wrong. It's a messy, poor setup. The second week of September sees a real wall of energy on the 7th and 8th, with combined readings over 2000 and swells hitting 12ft. That's expert-only territory if the wind was right, but with onshore and cross-onshore winds in the 28 mph range, it's just a washing machine. With that much wind and size, the setup looks more interesting for kite surfing than paddle surfing.

Don't hold your breath on this one. It's a flat, blown-out run with no standouts at all.

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.
