The Lowdown
Right, gather round. Rusty here, looking at the next couple of weeks for us. The surf is a bit of a slow burner to start, but keep an eye on the horizon – there’s a few windows that could get real special.
We’re starting off with a bit of a rough patch. The first few days, the wind is just a mess—strong cross-shore breezes, lumpy, chopped-up conditions. The swell is there, around 5ft to 6ft, but it’s short-period, wind-affected junk. Honestly, it’s not worth paddling out for. You’ll just get frustrated. This looks more interesting for the kite crew than anyone with a paddle.
The first real glimmer of hope comes on Saturday morning, the 12th. It’s still small, only 4ft, but the wind swings light cross-off, cleaning things right up. It’s surfable, but very ordinary. Just a warm-up, really.
Now, circle Sunday the 13th on your calendar. That morning is where it gets good. The wind drops to glass. Totally still. And we’ve got a clean 4ft groundswell rolling in from the NW with a long 13-second period. The energy is solid (504). That’s a beautiful combo for Praia do Norte. The conditions will be as good as it gets—clean, lined-up waves. It’s a standout for sure.
Monday the 14th morning is also worth a mention. Another glassy morning, with a 4ft NW swell at 12 seconds. The energy is moderate (404). It’s not as big, but it’ll be clean and fun. A good follow-up session.
The swell drops away mid-week, with tiny waves and onshore winds returning. A bit of a flat spell from Tuesday the 15th through the 18th. The wind is howling again, mostly cross-shore, making a mess of things.
But then, hold on. Saturday the 19th morning shows a pulse of longer-period swell, 3ft from the NW at 13 seconds, with a light cross-shore breeze. The energy is high (678), but the conditions are described as marginal. It’s a tease.
The real kicker, the one that has me buzzing, is way out there on Thursday the 24th of September. The forecast is showing a solid 7ft swell from the NNW, with a 9-second period, and a light cross-offshore breeze. The wave energy is massive (1210). This is big, powerful stuff. For a break like Praia do Norte, that’s serious. It’s an expert-only day, no doubt. For the experienced crew, it’s looking like an absolute classic. But remember, it’s a long way out, so keep checking in.
So, to sum it up: the first week is mostly a write-off, but Sunday the 13th morning is your best bet for clean, fun waves. The real heavyweight potential is on the 24th, but that’s for the big-dog crew only.
Stay frothy.
Rusty.

Information about the Praia do Norte Surf forecast
The above surf forecast table for Praia do Norte provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia do Norte can be found by selecting the local surf guide option on the grey menu. Our Praia do Norte 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 (Praia do Norte) 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 Praia do Norte 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.
Praia do Norte is 19 km (12 miles) from Sintra. If you plan a holiday in Ericeira, look for hotels and other accommodation in Sintra. Sintra has rooms for a wide range of budgets as well as car hire and transport links.
