The Lowdown

Alright, let’s take a look at what’s coming up for our local stretch.

Right now, we’re in a bit of a rough patch. For the first several days, from Monday the 14th right through to Sunday the 20th, it’s mostly poor surf conditions with cross or cross-onshore winds and choppy, lumpy waves. The water temperature is sitting at 63°, which is a touch warmer than normal for this time of year, so at least it’s comfortable out there even if the waves aren’t cooperating.

The first real glimmer of hope shows up on Monday the 21st. Early morning, we’ve got clean conditions with a gentle offshore breeze from the ESE. Swell is coming from the west at 3ft, with a period of 12 seconds, so there’s some decent groundswell energy in the water (combined energy of 306). It’s on the smaller side, but clean and surfable. That morning window looks like the best on offer for the whole outlook. Gwithian handles a WNW swell well, and with offshore wind, it’ll be tidy. Keep in mind it’s a fairly exposed spot and crowds are often there, so expect company if it’s looking good.

After that, the surf stays pretty ordinary through Tuesday the 22nd and Wednesday the 23rd, with small clean waves but nothing to write home about. The energy drops off, with combined readings around 246 and even down to 102 midweek.

Then we get another standout window on Thursday the 24th. Thursday morning, the wind goes offshore again from the ESE, light, and the swell picks up to 4ft from the west with an 11-second period (combined energy of 358). Thursday afternoon looks even cleaner – a slight air from the NE, cross-offshore, with 4ft swell from the west and a 12-second period (combined energy of 463). That afternoon session could be the pick of the bunch for the second week. Good shape, clean faces, and solid energy.

From Friday the 25th onwards, things taper off again. Small waves, light winds, but nothing really pushing through. There’s a bit of a gap from the 25th to the 28th with only small, weak swell and mostly cross or light offshore winds. By Monday the 28th, we get a fresh offshore from the east, but the swell is tiny and from the north, so not much to get excited about.

Tuesday the 29th shows a bit of a pulse late in the outlook – a 3ft to 3ft west swell with a very long 14-second period and fresh offshore east winds. Combined energy around 398-417, but the conditions are described as marginal, so it’s promising but less certain that far out.

Overall, the best windows are Monday morning the 21st and Thursday the 24th, especially the afternoon. That Thursday session has the best combo of size, period, and clean conditions. Don’t sleep on it.

Information about the Gwithian Surf forecast

The above surf forecast table for Gwithian provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Gwithian can be found by selecting the local surf guide option on the grey menu. Our Gwithian surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Gwithian) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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 Gwithian 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.
