Cabo Lastres Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at the next couple of weeks. It's a bit of a mixed bag up and down the coast, so let's get into it.

We're starting off with small, junky surf from a weak, short-period NW swell, coming in at around 1.6ft with an 8-second period. Thursday is pretty much a washout for any decent waves. The water temp is sitting at 71.2°F, which is a touch warmer than normal for this time of year, so you might not need the thickest wetsuit.

Friday the 28th is where things start to get a little more interesting. The morning is still small and unremarkable, but by the afternoon we see a pulse of new energy. The swell bumps up to 4.3ft from the WNW with a period of 10 seconds. The combined energy jumps into the moderate range (327), and with a light cross-offshore breeze, it should clean up nicely. This is looking like the first proper session of the window.

Saturday morning is the real standout for the first half of the week. The wind drops out completely and it turns glassy, with the swell holding at a clean 4.6ft from the NW. The period drops back to 8 seconds, but with zero wind, it's going to be super clean. This is your best bet for a fun, clean surf before the onshores kick in later in the day. The swell energy is moderate (286). The afternoon goes a bit crumbly with a cross-on wind, so get your waves in early.

Sunday and Monday are a bit inconsistent. There's still surfable swell, around 4.3-4.9ft, but the winds are less favorable, and the conditions are going to be a bit more mixed. Monday morning does have another window of clean, glassy conditions with a 4.9ft NW swell and a longer 10-second period. The energy is ramping up (399), which is a good sign. This is another chance to get some clean ones, but the window might be small as the afternoon turns to junky onshores.

After the 1st of September, it all fades out. We're looking at small, weak leftovers with energy readings dropping below 100. There's a long flat spell in there, from around the 2nd through the 4th, where there's just nothing doing. It looks like it tends not to stay this poor for long around here, but for now, it's pretty bleak. The water is still warm, so at least it'll be a nice paddle if you're desperate.

Then things get interesting again. On Saturday the 5th of September, a solid new groundswell is forecast. It’s still a week away so it's promising but not a guarantee, but the models are showing a strong pulse of long-period NW swell. The swell height builds from 3.6ft in the morning and hits 5.6ft by the afternoon, with a very long 12-13 second period. The wave energy jumps into the strong range (644 in the morning, 908 in the afternoon). The problem is the wind will be a cross-shore from the east, which will put a bit of chop on it. This is a powerful swell, but it might be raw and a bit lumpy. It'll be pushing towards the top end of things, so mainly for the more experienced crew.

The 6th keeps this energy but drops ever so slightly to 5.2ft, with the cross-shore wind still making things a little bit messy. Still, there will be plenty of water moving. Monday the 7th looks like the pick of that second week pulse. The swell eases slightly to 4.3ft, the wind goes light and glassy, and the energy is still solid at 318. That could be a proper clean day if it all comes together.

From there, it just fades out again into small, weak surf with onshore winds for the tail end of the forecast.

So, to sum it up: Make the most of Saturday morning the 29th for glassy, clean waves, and Monday morning the 31st also looks fun. The swell for the 5th and 6th of September is the biggest of the period, but the wind might spoil the party a little. The 7th of September looks like the best of the longer-range stuff.
