The Lowdown
Alright mates, Rusty here. Let's break down what's on the menu for the next couple of weeks.
We're starting off pretty slow. The first few days are a bit of a snooze, but things start to build as we go. The pattern is a quiet start, a little pulse mid-period, and then a huge ramp-up in size towards the end of the second week.
Right now, Monday the 27th is a dud with a tiny 0.7m NW swell and messy cross-shore wind at Carcavelos. Tuesday morning the 28th is our first real window. The swell is from the NNW at 1.3m with a 10-second period. The wind is a light cross-offshore from the NNW, so the surf will be clean. The combined energy is moderate at 356. It's a beginner-friendly size, and with clean conditions, this is a solid call for a morning paddle. The water temp is 21°C, which is about normal for this time of year.
Wednesday morning the 29th is similar, with a smaller 0.9m NW swell but still clean with a light cross-offshore breeze. The energy is weaker at 164. It's surfable, but nothing special. Thursday and Friday are pretty flat with very small, weak swells and stronger winds.
Then we get to the weekend. Saturday morning, August 1st, is a bit of a tease. You've got a 1.2m NNW swell, but it's a short-period 6-second windswell, making it weak and bouncy. The energy is 220, so it's moderate, but that short period makes it feel a bit messy. It's a marginal call.
The real story starts from Thursday, August 6th. The swell really starts to pump. But here's the thing for Carcavelos: it gets too big. Thursday afternoon sees a 2.3m NNW swell with a short 7-second period, and the energy is getting strong at 582. The wind is cross-offshore, but that size is pushing it for a beginner spot. By Friday, August 7th, we're looking at a 3.0m NNW swell, and the energy is very strong at 1401. This is expert territory, and the break is predicted to be too big for its usual setup. The wind is still cross-offshore, so the wave faces will be clean, but it's a serious, heavy wave.
The pattern continues through the weekend and into the next week. August 8th still has a hefty 2.4m NNW swell, and the wind shifts to a light cross-onshore, which isn't ideal. The size is still well over 2.5m, so it's only for the experienced crew. Then on August 10th and 11th, things get even more serious. Monday the 10th has a 2.5m to 3.0m NNW swell, and Tuesday the 11th is holding at 3.0m, with periods of 9-10 seconds. The combined energy on Tuesday morning hits a massive 1823, which is very strong. The wind is a strong offshore, so the conditions will be clean, but the sheer power and size will be intimidating. The setup looks more interesting for kite surfing than paddle surfing for most.
So, the standout session is Tuesday morning, July 28th. It's the best balance of clean, cross-offshore wind, a manageable 1.3m swell, and decent energy. It's a proper, clean, fun-sized wave. The big swell at the end is a spectacle, but it's only for the experts.
Rusty.

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