Avellanas Rivermouth Surf Forecast and Surf Report

Alright, Rusty here, let’s take a look at what the next couple of weeks have in store for us.

We're looking at Avellanas Rivermouth, a sandbar setup that’s exposed to the south swell. The water’s sitting at 86° right now, which is much warmer than normal for this time of year – you'll feel it, for sure. Overall, this isn’t a straight-up classic window; there’s a lot of chop and cross-onshore wind to wade through, but there are a few windows where it cleans right up.

Friday morning, August 7th, kicks things off with a 2ft SSW swell, but that 25 km/h ENE breeze has it cross-on and choppy, so not worth paddling out. The afternoon looks a little better with a light SE breeze, but the surf is marginal.

Saturday, August 8th, the morning is still messy with onshore wind, but the real standout is Saturday afternoon. The wind drops to glassy, SSW at just 5 km/h, and the swell pushes to 3ft from the SW with a 15-second period. That’s a long-period groundswell, so the energy is there (487 in the combined energy), and the waves will have shape. This is a very good option – clean, glassy surf at a rivermouth with that longer period. It’s a bit small for experts, but for intermediates, it’s your best bet in the near-term.

Sunday and Monday are mostly blown out again with fresh to moderate cross-onshore winds and lumpy conditions. Tuesday afternoon (August 11th) shows some promise with a clean, cross-off breeze and a 3ft, 18-second period swell. That’s a very long period, so the waves will be lined up and have plenty of energy (679), but a rivermouth can handle that well. It’s still a little small.

We hit a bit of a quiet patch in the middle of the week, with Wednesday afternoon (August 12th) offering another clean session with a 2ft swell and a light cross-off wind. It’s tiny, but glassy.

The next real standout is further out. Friday, August 14th, the swell picks up to 4ft from the SW with an 18-second period and some serious energy (1098). The wind is light from the SSE in the afternoon, so there’s a chance it’s rideable, but it’s a long way off, so keep your fingers crossed. The following weekend (August 15th-16th) gets bigger, hitting 5ft on Saturday morning, but the wind is howling at 35 km/h. That’s fresh and lumpy – more of a kite day than a paddle day.

Further out, Tuesday, August 18th afternoon looks promising again: a clean 4ft SW swell with a 16-second period and light WSW wind (10 km/h). Very clean conditions. Then Thursday, August 20th afternoon also shapes up nicely with another 4ft SW groundswell and a light offshore from the NW – that’s a clean, very good session on the cards.

If you’re picking the best of the bunch, Saturday afternoon (August 8th) is the clear winner for the first week: glassy wind, 3ft swell, good period. For the second week, keep an eye on Tuesday, August 18th afternoon and Thursday, August 20th afternoon – both look clean and fun, but they’re a bit of a wait.

Rusty.
