The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.

Right off the bat, I’ve gotta be straight with you – it’s a rough start. We’re looking at a real dry spell for the first week, with no decent surf on offer until well into the second week. The first few days are just a write-off: poor quality, messy wind, and tiny waves. From the 5th through to the 11th, it’s a sad story of onshore slop or flat, weak conditions. You’d be better off waxing your board for a long wait.

We finally get a pulse of life around the 12th, but it’s still not clean. The real standout, the only window worth circling on the calendar, is Saturday the 16th of August. That morning, Gwithian will see a solid 7 ft of swell rolling in from the west, with a period of 8 seconds. The combined energy will be pumping at 544, so there’s some serious power behind it. However, the wind is cross-onshore from the northwest at 16 mph, so it’s going to be a bit lumpy and choppy. This is big, strong stuff – over 8 ft, so this is strictly for the experienced crew. Beginners, stay on the sand for this one. The water temp is a touch warmer than normal for this time of year, sitting at 65°.

The following day, Sunday the 17th, shows some promise too but it’s a step down in size. The morning brings a 4 ft west swell with a 9-second period, and a clean cross-offshore breeze from the south-southeast at 19 mph. The energy is moderate at 257. It’s a much more manageable size, and the clean wind should make for some fun, lined-up waves. This is probably the best bet for the intermediate surfer during this whole outlook.

So, there you have it. A long, quiet stretch, then a big, powerful weekend. If you’re an expert, the 16th is your day. For everyone else, the 17th morning is where it’s at.

Rusty.

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.

Gwithian is 6 km (4 miles) from Camborne. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Camborne. Camborne has rooms for a wide range of budgets as well as car hire and transport links.
