The Lowdown
Right then, let’s talk about Gwithian. Looking at the sixteen-day window, it’s a tough run. The spot is consistent, but the conditions just aren't playing ball. There’s a real gap of poor surf quality to get through before anything starts to look half decent.
The water is a touch warmer than normal for this time of year, coming in at 64°.
We kick off Monday the 20th of July with a tiny 0.3m (1ft) ripple from the WNW. The wind is a cross breeze, and the combined energy is weak (56). It’s poor. Tuesday and Wednesday are similar, with a bigger swell but nasty wind. The swell jumps to 1.0m (3ft) on Tuesday, but it’s a short-period, 5 to 6 second wave from the North, with a moderate cross-breeze keeping it messy. The energy is still weak (98). Wednesday is more of the same, with a 1.1m (4ft) northerly swell, but a fresh cross-breeze chops it up properly.
Thursday the 23rd offers a little hope. The morning sees a 0.9m (3ft) northerly swell with a cross-offshore breeze and clean conditions. The energy is still weak (76). It’s not a standout, but it’s the best we’ve seen. The afternoon flattens out again.
The next few days are a write-off. Friday the 24th is tiny, and from Saturday the 25th through to Tuesday the 28th, the swell picks up a bit, but the wind is onshore or cross-onshore, making everything choppy and lumpy. The swell reaches 1.5m (5ft) on Sunday the 26th, but it’s blown out. The energy is moderate (196), but it’s not worth it.
Now, there is a glimmer near the end of the first week and into the second. Wednesday the 29th of July has a morning with a 0.5m (2ft) westerly swell and a light cross-offshore breeze, giving us clean conditions. Still small, but clean. The real standout, though, is Thursday the 30th of July. The morning brings a 0.5m (2ft) westerly swell with a gentle offshore breeze from the East. The afternoon is also clean, with a 0.5m (2ft) swell from the WNW and a 10-second period, the best period we’ve seen. The energy is low (57), but with offshore wind and a longer period, the waves will have shape. This is the best on offer for the whole outlook.
The long-range stuff into the first week of August looks poor again. Friday the 31st of July and the first of August are messy with fresh, lumpy winds. The swell on the 3rd of August hits 1.1m (4ft), but it’s straight onshore wind. Not one for the paddle.
So, to be honest, this is a forgettable run. The only session worth circling is Thursday the 30th of July. That’s your window. It won’t be big, but it’ll be clean. The rest is a right-off.

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.
