The Lowdown

Alright, let’s get real. It’s Rusty, and I’ve been pouring over the charts for Mawgan Porth. And I’m not gonna lie, the next week is a tough one to be a surfer here. There’s a big dry spell up front, and we’re not looking at anything worthwhile until early September.

The water’s sitting at 65°F, which is a bit warmer than average for this time of year, so that’s one small comfort if you just want a swim.

The first week is a battle. From the 26th of August through the end of the month, it’s all onshore wind and wind-affected junk. The swell is there, but it’s short-period, around 7 seconds, and the wind just tears it apart. Friday the 28th sees a bump to around 5ft, but it’s blown out onshore. The weekend turns into a full-blown mess. Saturday the 29th, we’re looking at 8ft of lumpy, wind-blown swell, with the energy reading (1058), but it’s just a closeout fest. It’s not surf, it’s a washing machine. The 30th and 31st are more of the same – strong winds, lumpy conditions, and onshore slop.

The first few days of September don’t offer any change. We’re seeing 4ft to 6ft of swell, but it’s all cross-onshore and choppy. This area, with a beach and river setup, is going to be much more interesting for kite surfers than us paddle surfers during this stretch.

Then, a change in the wind. On Saturday the 5th of September, the breeze swings around to a cross-shore direction. Finally, in the morning, we get a bit of relief. There’s 6ft of W swell with an 11-second period, and the energy is more manageable at (843). The afternoon looks even better with a faint NNW breeze and the swell coming in at 6ft. There were some clean ones to be had. This is the standout for the first part of the window, but it’s not perfect, so manage your expectations.

The next real hope is Wednesday the 10th of September. The morning has a clean, cross-offshore breeze from the NE. Swell is a solid 7ft from the W with a 10-second period, and the energy is pumping at (955). The afternoon is a big one. The swell jumps to 8ft with an 11-second period, and the energy is massive at (1615). This is big and powerful, a real expert-only day. It’s the best looking surf of the whole 16-day forecast, but it’s also a long way off, so treat that one with a bit of caution.

The day before, the 9th, is a write-off with onshore winds and a messy 6ft. So, circle Saturday the 5th and keep an eye on the 10th. The rest is a grind. Stay patient, Rusty.

A general guide to surfing at Mawgan Porth can be found by selecting the local surf guide option on the grey menu.

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.
