The Lowdown
Howdy, Rusty here again. Let's break down this surf window.
So, for the next sixteen days, Gyllyngvase Beach (United Kingdom) is looking mostly dead. There's a long gap with nothing rideable until we get to the end of the second week. For days on end, the combined energy of all swells directed here is basically zero or single digits – that's weak, useless energy.
You're looking at a flat spell from now all the way through to the morning of Wednesday, September 25th. There are a few tiny bumps from the south and southwest with periods up to 18 seconds, but the heights are barely a trace, and the wave energy numbers are all under 100 (weak). The winds will be clean and offshore from the northwest at times, which is a shame to waste on flat water.
The only real event in the whole forecast lands on Friday, September 25th. The morning brings a 8ft swell from the west-southwest with a 7-second period, and the combined energy hits 537 (moderate). The afternoon steps it up to a 10ft swell from the same direction with a 10-second period, and the energy rockets to 1744 (strong). The water temp is likely about average for the time of year; no big anomaly is noted. But the wind is a light cross-onshore from the east, not the best. That size (over 8ft) is strictly for experts. Gyllyngvase is a sheltered, inconsistent beach and reef setup, and a 10-second period groundswell can get walled and straight on a beach break. That much size with an onshore breeze will be ugly and powerful. That setup looks more interesting for the kite crowd than paddle surfers.
After that one day, it vanishes again. The 26th of September drops straight back to nothing. A long, quiet run with just one rough but big option over a week out. Still, these forecasts can change, and it doesn't stay this empty forever.
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 Gyllyngvase Beach 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.
