Alright, Rusty here again. Let’s talk about Mawgan Porth in feet and miles per hour. It’s a quiet forecast, and I’ll be honest—there’s not much to get excited about. The river mouth is dealing with onshore winds and weak, small swell for most of the period. No standout days, but a couple of early mornings could save a session if you’re not fussy.
The water is a bit warmer than usual for July, at 63°F, with an anomaly of 3°F above normal. That’s notable.
First surf shows up Friday, 3rd July afternoon: 4ft west swell, 10-second period, combined energy 340 (moderate), but the onshore west wind at 12 mph ruins it. Poor surf.
Saturday, 4th July is similar: 3ft west swell, energy drops to 198 then 180, wind onshore from the WNW at 9-12 mph. No good.
Sunday, 5th July: 3ft and 3ft, period 9 seconds, cross-onshore wind. Energy 166 and 136. Choppy and small.
Monday and Tuesday (6th-7th July) drop to 3ft and 2ft. Energy falls below 100 into weak territory. Onshore and cross-onshore winds.
Your best bet is Wednesday morning, 8th July: tiny 2ft west swell, 9 seconds, energy only 87 (weak), but the wind goes glassy from the north at 3 mph. It’s surfable but very ordinary. Thursday morning, 9th July is the same story: 2ft, glassy NE wind at 3 mph, energy 90. Clean but tiny.
Friday morning, 10th July offers a light cross-offshore NNE breeze at 3 mph, 2ft west swell, energy 89. Clean, but still very small.
After that, it’s a long stretch of poor conditions. From Friday afternoon through to the end of the forecast, winds are onshore or cross-onshore, often fresh breeze at 12-18 mph or more. Swell stays mostly under 3ft. Sunday, 12th July afternoon shows moderate energy at 249 with a risk of thunderstorms, but the onshore wind is strong at 18 mph. Better for kite surfers.
Friday afternoon, 17th July bumps up to 5ft from the north, period a short 6 seconds, energy 251 (moderate), but the onshore WNW wind at 9 mph and the short period kill any quality.
For beginners, the tiny glassy mornings on 8th, 9th, and 10th July are okay for a longboard practice. For everyone else, this is a blank run. The consistency is poor, and the wind won't let up.
Rusty.
