Mawgan Porth Surf Forecast and Surf Report

Howdy, Rusty here. It’s a quiet start, so don’t get your hopes up too early. The first surf worth getting wet for doesn’t show up until Wednesday the 12th of August, and even that’s pretty average. After that, we get a stretch of small, choppy, or onshore junk with just a couple of bright spots. The real standout is shaping up for Friday the 21st of August, but that’s a long way off. Here’s the rundown.

First up, Mawgan Porth (river). Through the 7th and 8th of August, it’s tiny – ankle to knee-high at around 0.7ft to 1.0ft from the W/WNW with a short, weak period around 9 seconds. Combined energy is weak, in the twenties (22, 25). The water temp is 65°, which is a touch warmer than normal for this time of year – feels nice for a float, but there’s no surf. Saturday afternoon the 8th does go glassy with an ENE breeze at 3 mph, but with swell that small it’s a flat spell.

We skip to Wednesday the 12th of August. That morning sees a bump to 3ft from the W with a 10-second period, moderate energy (125), and clean offshore conditions from the SE at 6 mph. It’s surfable, but nothing special. By afternoon, the wind switches to a NW cross-onshore at 9 mph and messes it up.

Thursday the 13th of August is similar – morning is choppy cross-onshore, but the afternoon pushes 4ft from the W with an 11-second period and energy jumping to 272. The wind stays cross-onshore though, so it’s messy. Friday the 14th stays cross-shore and small, holding 4ft but with that moderate cross-shore chop. Energy hangs around 200 (201, 194).

The weekend of the 15th and 16th drops right back to 2ft to 2ft with short periods (6-7 seconds) and energy in the thirties to sixties. Wind is mostly cross or cross-off, so it’s clean but tiny. Monday the 17th bumps up to 4ft from the W with an 8-second period and solid energy of 174, but with onshore wind from the WSW to W at 9 mph, so expect lumpy, blown-out conditions.

Tuesday the 18th of August morning has a small window: 2ft from the W, 8-second period, clean with a light SE cross-off breeze at 3 mph. Energy is only 68, so it’s weak, but rideable. Then it’s back to mush through Wednesday the 19th.

Now here’s the big one. Friday the 21st of August is the standout of the whole outlook. That morning, we’ve got 8ft of WNW swell with a 9-second period and combined energy hitting a massive 817 – that’s strong wave energy. The wind is light from the south at 6 mph, giving clean, cross-off conditions. The forecast says *expect very good surf conditions*. That’s your session. It’s a river break so with that much energy it’ll be powerful. 8ft is expert territory, not for beginners. The period is moderate at 9 seconds so it won’t be too wonky. Later that Friday afternoon the wind swings and it gets messy. Saturday the 22nd and beyond drop back down.

So, the call is: wait for Wednesday the 12th for a tiny, clean-ish morning, but the real fire is Friday the 21st of August morning. That’s the one to plan for. Long-range, so keep tabs on it, but it’s got serious potential.

Stay salty,
Rusty
