The Lowdown
Right, I've had a look at the charts for Mawgan Porth, and to be honest, it's looking pretty bleak for the next couple of weeks. There's very little to get excited about for a surfer.
We've got a long run of mediocre to poor conditions. The combined swell energy struggles to get into three digits for most of the first week, hovering around weak to moderate, with values like 60 and 136. Monday the 10th and Tuesday the 11th have tiny swell, a messy 1 ft to 3 ft from the WNW, and mostly cross or cross-off winds. That's barely a ripple.
We do see a slight bump in swell around Wednesday the 12th, with a 3 ft to 3 ft W swell and a 10-second period, giving us a combined energy of 126. It’s a river-mouth setup, and with light cross-off winds, it might look ridable, but it's still very marginal. The waves that do come through will be weak and the crowds could be a factor as it's a popular spot for beginners.
Things get a bit bigger but dirtier from Thursday the 13th through the 15th. Swell hits 4 ft to 4 ft from the west, with the combined energy reaching a moderate 274, but the winds are messy cross or cross-on. That's going to chop it up and make for a frustrating session. By Saturday the 16th, the swell drops way off again.
There is one glimmer, but it's a long way off. On the morning of Tuesday the 25th of August, we get a late burst of cleaner energy. We see a 5 ft W swell with an 8-second period and a combined energy of 290, and the wind looks like it will be light and cross-off. That setup points to cleaner conditions and might be the best shot you get, but it's far out and these long-range calls are always a bit of a gamble. The water temperature is about average for the time of year.
For the rest of the outlook, it's pretty grim. There are long gaps with no recommendation. The consistent breaks tend to stay on the poor side for this area, which is a bit of a tough run. On those bigger, windier days, the beach-and-river setup will look a lot more appealing for kite surfing than for a paddle surfer.
Stick with it, but don't expect much.
