Avellanas Rivermouth Surf Forecast and Surf Report

Alright, let's get down to it. The long-range is where the magic is hiding, but you're gonna need some patience. There's a flat spell first, then the ocean remembers how to send us something.

Starting at Avellanas Rivermouth (Playa Avellanas). The water is running about 87°F, which is a few degrees warmer than normal for this time of year – real nice, no wetsuit needed. But the first few days are pretty weak. Friday morning is a no-go: cross-on breeze and junky conditions. The afternoon cleans up a bit with a cross-off, but the swell is tiny and there's no push behind it.

Saturday and Sunday follow the same pattern – small SW swell, mornings chopped by the NE breeze. You're looking at knee-high dribble. Monday afternoon has a long-period pulse (18 secs) but only 2ft of swell. It's clean, but it's a tease. Not worth getting wet for just yet.

The first real window opens Tuesday the 15th. The morning is still poor, but the afternoon – now we're talking. The wind drops to almost nothing, a light SSW cross-off, and the swell bumps to 3ft from the SW at 17 seconds. The energy is building, hitting 809. It's still small, but the quality is there. That sandbar will start to show some shape. This is the first day I'd actually paddle out.

Wednesday the 16th is another step up. The morning has a clean 4ft SW swell, but the wind is straight onshore – messy. The afternoon is the winner. That SSW cross-off keeps it clean, the swell holds at around 4ft, and the energy is still pumping. This is the pick of the first week – a proper session.

Thursday and Friday keep the quality going, with smaller swell but clean conditions. Friday morning the 18th is glassy – zero wind – with a clean 3ft. It's small, but perfect. Saturday morning the 19th is also glassy on a long-period 2ft. Days for the longboard, not the shortboard.

The real standout is shaping up for Sunday the 20th. Light air, cross-off wind, and a 3ft SW swell at 19 seconds. The combined energy is strong. It's clean, it's consistent, and the rivermouth should be firing. This is the one to circle in the calendar.

The second week is a different beast. Monday the 21st turns onshore and messy. Then Tuesday the 22nd is a giant. The swell jumps to 7ft from the S, then hits a solid 12ft by the afternoon – huge energy. But here's the catch: it's too big for this break. It's also a short-period, wind-driven swell. The forecast literally says it's too big. This is not for the faint-hearted. If you're on the beach, it'll be a show, but paddling out? Expert-only, and even then, it'll be a washing machine.

Wednesday the 23rd drops to 6ft and is cleaner in the afternoon. Thursday the 24th sees the wind swing offshore in the afternoon with a clean 3ft set. The rest of the month trails off into smaller, cleaner waves again, with glassy mornings on the 26th.

So, to wrap it up. The first few days are a write-off. Don't bother. The first real window is Tuesday afternoon the 15th, with Wednesday the 16th and Sunday the 20th being the best of the cleaner, smaller stuff. The massive swell on the 22nd is a spectacle, but not a practical surf day here. The set-up looks way more interesting for the kite crew than for us paddle surfers. The long-period swells are best here at the rivermouth, so keep an eye on those. Give it time, and it'll pay off.
