The Lowdown
Right then, let's have a look at what's on the cards for Gwithian over the next couple of weeks.
To be honest, this is a bit of a tricky start. The first week is a write-off for any decent surf. We've got a lot of onshore and cross-shore wind messing things up, with choppy, lumpy conditions right through until the 4th of September. The swell energy is there, but it's all over the place, and the wind just won't play ball. It's one of those frustrating runs where you just have to wait it out.
The first real glimmer of hope comes on Saturday morning, the 5th of September. That's your standout. The wind goes glassy with a light breeze from the ENE, and we've got a 4ft groundswell rolling in from the west with a 10-second period. The combined energy is moderate at 297, but the key here is that glassy surface. It's going to be clean and fun for a beginner-friendly wave. It won't be huge, but it'll be the best surf you'll see for a while. Keep in mind, it can get crowded here sometimes.
After that, things drop off again. We get a few days of clean offshore winds on the 6th, but the swell is tiny – barely 2ft to 2ft – and the energy is weak (41 to 66). It's not worth paddling out for. The following week is a mix of onshore slop or that strong cross-shore wind, with a couple of days where the swell picks up to 8ft on the 8th and 9th, but the wind is just too messy. That size with that wind is more of a kite-surfing show than a paddle session.
Looking further out, the second week gets a bit more interesting, but it's less certain. Monday the 14th afternoon could be promising – a 4ft groundswell with a very long 12-second period from the west, and a moderate offshore wind from the east giving clean conditions. The energy jumps up to a moderate 485. Tuesday the 15th morning is also worth a mention, with a 4ft swell and the same long 12-second period, with clean, light cross-offshore winds. Those long-period west swells can be a bit straight at a beach break, but with clean winds they should offer some nice shaped waves. It's not a guaranteed classic, but it's the best bet in the second week.
So, to sum it up: grit your teeth through this first week of blown-out rubbish. Your one true standout is the glassy morning of Saturday the 5th. After that, keep an eye on the 14th and 15th for a chance of some cleaner, longer-period groundswell.

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.
