The Lowdown

What’s up, everyone? Rusty here. Let’s be straight with you: the next few days are looking pretty bleak. There’s a whole run of onshore junk and not much size, so you might want to find something else to do for the best part of a week.

The water is unusually warm for this time of year, sitting at 65°F, which is a solid 4°F above normal. Small comfort, but we’ll take it while the surf is flat.

The first faint glimmer of hope arrives on Tuesday the 15th. It’s looking clean with a cross-offshore wind, but there’s hardly any energy. We’re talking about 2ft of swell from the WNW with a long 12-second period. It’s skinny, but if you’re desperate, it might be ridable. The afternoon bumps up to around 4ft, but the model calls it marginal. There's moderate energy in the water at 311, but it's nothing to write home about.

Wednesday the 16th is a write-off. A big pulse of swell hits, pushing up to 10ft, but it brings 40 km/h winds with it. The energy numbers are huge, hitting 1476, but it’s going to be a complete washing machine. That’s not surfing, that’s a battle for your life. For a river break like this, it’s going to be blown out and dangerous. Honestly, the kitesurfers are going to have a field day.

We’re back to waiting after that. The next bright spot is on Monday the 21st. The morning looks clean with a nice cross-offshore breeze and around 4ft of swell. The period is a solid 10 seconds, and the energy is moderate at 410. The models are actually saying “expect good surf conditions,” which is the first bit of decent news in a while. The light breeze should keep the surface clean for the banks to work.

Now, for the one to circle on the calendar: Thursday the 24th. It’s a long way out, so take it with a grain of salt, but the morning is looking like our best session in the entire forecast. We’ve got clean conditions, a cross-offshore breeze, and about 3ft of swell from the W with an 11-second period. That’s proper groundswell, and it should wrap into the river mouth with some real shape. The energy is moderate at 290, which should be enough to give you a fun, rippable wave without it being a struggle. This is the one to hope for.

So yeah, a tough stretch ahead, but there are a couple of little windows of opportunity showing themselves late next week. Stay patient, keep an eye on the forecast, and we might just get a few clean ones.

Rusty, out.

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.
