The Lowdown
Alright, Rusty here again. Let’s break down the next 16 days at Carcavelos with the numbers you’re used to.
The first week is a bit of a slow burner. Not much to write home about, but there are a few moments to get wet.
Thursday morning, September 3rd, you’ll see waves around 3 ft from the NNW, with a short period of 7 seconds. The combined energy is weak at 126. The wind is a light offshore from the NE at 6 mph, so it’s clean, but the waves are small and weak. Friday morning, September 4th, gets smaller to 2 ft from the WNW, but the wind goes glassy, dead calm. The surface will be perfect, but the swell is tiny (energy 81). Saturday morning, September 5th, is similar with 3 ft from the WNW, a 9-second period, and a clean cross-off breeze from the NNE. The energy is still low at 118.
The first real pulse arrives Sunday morning, September 6th. The swell jumps to 4 ft from the NW, with a long period of 12 seconds. The energy is moderate at 506, and the wind is a clean cross-off from the NNW. This is the best of the first week, but it’s still only a marginal call. Monday, September 7th, holds similar size (5 ft) and period (12 seconds) from the WNW, with a fresh cross-off breeze (19 mph). Tuesday, September 8th, gets bigger at 6 ft to 7 ft from the NNW, but the period drops to 7-9 seconds, making it a bit messy. The wind is strong at 16-19 mph.
The middle of the week from September 9th to the 14th is a washout. The wind stays strong, 16-19 mph from the NNW, and the surf is poor. The swell hangs around 2 ft to 4 ft, but the wind is relentless. Thursday, September 10th, is a good example: 4 ft waves but a 19 mph cross-off wind. It’s clean, but the wind is howling, making it a tough paddle.
The real standout is way out there. Wednesday morning, September 16th, is the one to circle. The swell is 6 ft from the WNW, with a very long period of 15 seconds. This is proper groundswell. The combined energy is a massive 1460, which is strong. The wind is glassy, dead calm. The forecast says "excellent surf conditions for experienced surfers", and with 6 ft, it’s powerful. The long period (15 seconds) means more energy and longer lulls between sets. Wednesday afternoon is also very good, with 6 ft from the WNW at 14 seconds, but the wind turns a little cross. Thursday morning, September 17th, is also a good option with 4 ft from the WNW at 12 seconds and glassy conditions from the east.
So, to wrap it up: the first week is a waiting game. The best bet is Wednesday morning, September 16th. That’s your standout. The water temp is about 68°F, which is normal for this time of year, so a 3/2 wetsuit is fine. The crowds at Carcavelos are often busy, so expect company.
Rusty, signing off.

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.
