The Lowdown
Alright, let’s get into what’s cookin’ for the next couple of weeks.
Honestly, the first week or so is pretty slim pickings. The swell is tiny, and the wind is mostly onshore or cross-on, making for real choppy, weak lines. The combined energy is low, stayin’ under 100 for most of it. You’d be lookin’ at bumpy, un-rideable lumps. Not worth wetting a wetsuit for.
The first real sign of life shows up on Sunday, July 20th afternoon. The swell bumps up to about 3ft from the NNW, with a 8-second period, and the combined energy hits a moderate 137. The wind is still onshore, so it’s not perfect, but it’s a step up from flat.
Then, around Saturday, July 26th morning, things get real interesting. The swell jumps to 8ft from the NNW, with an 8-second period, and the combined energy hits 960 – that’s strong. But the wind is blowin’ onshore at 12 mph, so it’s gonna be lumpy. This is solid, powerful surf, but a handful.
The big standout, the one to circle, is Monday, July 28th morning. The swell is 7ft from the NNW, period is 8 seconds, and the combined energy is a very strong 602. The wind is cross-on from the NNW at 16 mph, so it won’t be glassy, but the power is there. The direction is a dead-on match for Coxos (Coxos, Portugal). This is expert territory – over 8ft it’s for experts only, and 7ft is still a serious wave. The water temp is about 66°F, just a touch cooler than normal for this time of year.
Tuesday, July 29th morning also looks good. The swell is 6ft from the NNW, period 8 seconds, and the combined energy is 514. The wind is lighter, from the N at 6 mph, and cross-on, so the surface will be a little cleaner. The size is still big and powerful, so it’s for experienced surfers only.
The second week is all about size and power, but the wind is a constant headache. It’s mostly onshore, so the waves will be raw and not super clean. If you’re a strong paddler and don’t mind a bit of chop, the last few days of July have some serious juice.

Information about the Coxos Surf forecast
The above surf forecast table for Coxos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Coxos can be found by selecting the local surf guide option on the grey menu. Our Coxos 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 (Coxos) 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 Coxos 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.
