The Lowdown

G'day, I'm Rusty. Let's have a look at what's on the table for Carcavelos over the next couple of weeks.

Right off the bat, we've got a bit of a slow start. The first real surf window kicks off on Thursday morning, September 10th. It's not a giant day, but it's got a clean 6ft swell from the NNW with a short 8-second period, and the wind is a cross-off from the north. The water is sitting at 68°, which is about normal for this time of year. The combined energy is moderate at 487. It's a solid, surfable morning for a beginner-friendly spot like this.

Thursday afternoon, the swell ticks up a touch to 6ft, and the period stretches out to a much nicer 11 seconds, so the waves will have a bit more punch. But a fresh 19 mph cross-off wind from the NNW will be blowing, making conditions a bit of a battle. It's a case of the surf being there but the wind making it a chore.

We clear out for a bit. Friday morning, September 11th, is a decent little window. We're looking at 3ft of clean, cross-off swell from the NNW with a 10-second period. The energy is low at 220, but it's clean and calm. A good morning for a longboard or a learner.

Then there's a bit of a lull. Saturday is pretty ordinary, with a glassy 4ft wave at 7 seconds in the morning, but it's just not got any juice. The rest of the weekend is a write-off thanks to onshore winds.

But hold on. Sunday morning, September 13th, is a real standout. The swell drops to 3ft, but the period is a glorious 13 seconds – a proper groundswell. The wind is light and cross-off from the ESE, making for clean lines. The wave energy is moderate at 338. This is a morning for the longboarders and the traditionalists.

Monday morning, September 14th, is a dead-set classic. A glassy 3ft swell from the NW with an 11-second period, and the wind is a flat calm, zero mph. It's going to be pure, clean, and absolutely beautiful. The energy is a solid 291. This is the best of the first week, no question.

The middle of the week gets a bit weird. Wednesday, September 16th, a big lump of energy arrives – a 10ft swell from the NNW with a 1227 energy reading. But the wind is a strong cross-off. For a beginner spot like Carcavelos, that's just too big and messy. This is one for the experts only, if anyone.

The real highlight, though, is Thursday morning, September 17th. A clean 6ft swell from the NNW, a 9-second period, and a light offshore wind from the NNE. The energy is a meaty 951. This is the pick of the bunch for the second week. Get on it.

We then have a bit of a choppy spell until the next big moment. Monday morning, September 21st, is a monster. The swell is 4ft from the NW, but the period is a staggering 14 seconds. The energy is a massive 1252. And the wind? Glassy, dead calm, from the NE. This is a world-class morning for experienced surfers, but the long period will make it a bit straight at a beach break like this. It's best on the points.

The last proper standout is Thursday morning, September 24th. A clean 4ft swell from the NW with a 12-second period, glassy conditions from the east, and an energy reading of 568. It's a beautiful, clean, classic autumn morning.

So, to wrap it up: the first week is a slow burn, but Sunday the 13th and Monday the 14th are absolute crackers. The second week has a slab of size on the 17th, and if you're experienced, the 21st is the one to circle. The end of the month looks clean and consistent.

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.
