The Lowdown

G’day, Rusty here. Let’s be straight with you: this outlook for the next 16 days is a tough one. If you’re hanging for a proper wave, you’re gonna be waiting a while. The first real glimmer of anything worth paddling out for doesn’t show up until Saturday, July 25th, and even then, it’s not a classic. There’s a long gap of small, weak, or messy conditions before that.

For the first week and a half, it’s all pretty flat or chopped up. From Wednesday, July 15th, right through to Friday, July 24th, we’re looking at tiny waves – mostly 1 ft to 2 ft – with combined swell energy barely cracking 65 (weak). The wind is often cross-shore or cross-onshore, especially from the north, which just messes up whatever little bump there is. There are a few glassy moments on the mornings of July 22nd and 23rd, with a light south wind, but the swell is still only 1 ft with a period of 9 seconds – that’s barely a ripple. Unless you’re on a foamie and just want to sit in the water, it’s not worth it.

Then, finally, on Saturday, July 25th, things change. The swell picks up to 5 ft from the NNW, with a period of 6 seconds. That’s a short-period wind swell, but it’ll bring some punch. The combined energy jumps to 245 (moderate) on the morning and 276 (moderate) in the afternoon. Now, the wind is cross-onshore from the NNW in the morning, shifting to WNW in the afternoon, so it won’t be glassy – expect some chop. This is the one standout in the whole period, but it’s not for beginners. At 5 ft, it’s pushing into the bigger range, and with that short period, it’ll be a bit dumpy and hard to read. This is more for the experienced crew who can handle a bit of a beast.

The break here is Mawgan Porth, a river-mouth setup that’s fairly exposed to the WNW. The water temperature is about average for the time of year, nothing unusual to report. Crowds are “sometimes” an issue, so you might have some company, but it won’t be a circus.

After that, Sunday, July 26th, drops back to 3 ft from the north, with a fresh cross-onshore wind from the WSW – choppy and lumpy. Then Monday, July 27th, is back to 0.7 ft, and the rest of the outlook fades into small, onshore junk. Nothing else to get excited about.

So, bottom line: if you’re a seasoned surfer and you’re desperate, mark Saturday, July 25th, at Mawgan Porth. The morning might be the best bet before the wind really picks up. Otherwise, the board stays in the car. The swell energy is just too weak and the wind too messy for most of the run.

Rusty.

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.
