The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for Mawgan Porth over the next couple of weeks.
Honestly, mate, I’m looking at this and it’s a tough stretch. We’ve got a long, lean run of poor conditions stretching right through the 16-day window. There’s no real standout session to get excited about, and no proper recommendations to point you toward. The water temp is sitting at 65°, which is a touch warmer than normal for this time of year, so at least a dip won’t be a shock to the system.
We start off Monday, 20 July with a glassy morning and a tiny 2ft northerly ripple, but the combined energy is weak (33). It’s just not enough to push any real shape. Winds go cross-shore and ramp up in the afternoon, making a mess of things. Tuesday and Wednesday bring a bit more size – 3ft from the NNW and N, but the periods are short, around 5-6 seconds. That’s windswell, short and crumbly, and the wind stays breezy and cross or cross-off, so surfaces are clean-ish at best but the waves are poor.
Thursday morning, 23 July, is the closest we get to anything rideable. Glassy conditions, 3ft from the NNW, and the energy nudges up a bit (64). The wave comment says “surfable waves but very ordinary conditions,” and I’d agree – it’s a window of cleanish, small waves, but nothing to write home about.
From there, the outlook drops off a cliff. The end of July and the start of August are dominated by cross-onshore winds, tiny swell (mostly 1ft to 2ft), and weak energy figures staying well below 100. There’s a brief uptick on the morning of 4 August with 3ft and clean cross-off winds from the NNE, but the period is short again (6 seconds) and energy is still modest (75). It’s a tease, not a treat.
So, to sum it up: there’s no good surf on offer across the entire 16-day window. For an area like this, a blank run can happen, but it doesn’t tend to stay this poor forever. Keep an eye on it – forecasts can change.
Rusty.
