The Lowdown
Alright, Rusty here. Let’s talk about what we’ve got coming down the line for our part of the coast.
First up, let’s talk water temp. It’s currently running 70°, which is a touch warmer than normal for this time of year. Not a big deal, just a nice little bonus.
Now, the surf. The next few days are going to be a write-off for any decent surfing. Tuesday the 15th is a total mess with a moderate cross-shore chop and weak, short-period swell – not worth getting wet for. We’re looking at a frustrating gap of a few days here. Wednesday the 16th morning goes glassy, but the swell is still weak and the conditions are just “ordinary” at best. Not good.
Things start to wake up on Thursday the 17th. That morning session is the first real glimmer. We get a glassy surface with a clean 5ft NW groundswell at 11 seconds. That’s a lovely combo, and the combined energy is moderate at 480. It’s not huge, but the clean conditions and that long period will make for some nicely shaped waves at the point. This is the first standout of the window.
Then we skip ahead to Friday the 18th. The morning is a bit messy with a cross-shore wind, but hold on for the afternoon. That’s where it gets real. We’ve got a 8ft NW swell with a *very* long period of 16 seconds pouring in. That’s a big, powerful groundswell. The combined energy is strong at 3178. Now, that size (8ft) and that long period mean this is for experts only. It’s a powerful, demanding wave, and at a point break like Cabo Lastres, it’s going to be well-defined but challenging. If you’re a pro, that afternoon is the absolute highlight of the entire outlook.
Saturday the 19th is still solid, but that cross-shore wind picks up in the afternoon and messes with the shape. The 7ft swell in the morning is still sizeable, but the wind is a factor. Not as good as Friday.
We get a clean-up on Sunday the 20th morning. A clean 5ft NW groundswell with a nice 11-second period and a light offshore breeze. That’s a very user-friendly size and setup, perfect for a solid session without the chaos of Friday.
Monday the 21st is a bit lumpy, but then Tuesday the 22nd morning is another gem – dead glassy with a 4ft NW groundswell at 12 seconds. Combined energy is moderate at 332. It’s a smaller day but perfectly clean.
We taper off through the next week. Wednesday the 23rd and Thursday the 24th mornings both offer glassy conditions with small but clean groundswell. Thursday morning is a standout for consistency and clean conditions – 5ft NW at 13 seconds, glassy, with a combined energy of 678. That’s a proper, fun, clean point wave. The action is in the mornings.
By the end of the month, from the 27th onward, it really drops out. We get a tiny blip on the 29th with some short-period windswell, but nothing worth paddling out for.
However, look at the very end of the forecast. On the 30th of September, Wednesday morning, it fires back up. We’ve got a glassy 6ft NW swell with an 11-second period. Combined energy is moderate at 770. That’s a very promising close to the window, but being that far out, we keep an eye on it.
So, to wrap it up: the real stand-out sessions are Friday afternoon the 18th for the experts and Thursday morning the 24th for a clean, fun, glassy session. Thursday the 17th morning is also a solid bet for clean early waves.
Rusty out.

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