Avellanas Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the Avellanas Rivermouth sandbar over the next couple of weeks.

We’ve got a real mixed bag ahead, but the heart of the action is definitely in the first week. The water is sitting at a warm 86°, which is a touch warmer than normal for this time of year – feels like a warm bath out there, just how we like it.

The series kicks off proper on Saturday the 25th of July. The morning is a bit average with a light cross-onshore breeze and a small 3 ft swell from the SW, but the real story is Saturday afternoon. The wind swings around to a light offshore WNW breeze, cleaning up the same 3 ft SW swell. The combined energy is pumping at a solid 936 (moderate energy), and it’s going to be clean. This is a solid session for a longboard or a funboard.

Sunday the 26th sees the swell bump up to 4 ft with a 19-second period, but the wind is onshore in the morning and cross-shore in the afternoon, so it’s not the best. Monday the 27th is similar, with the same size and period but a cross-onshore wind making it fairly choppy. Not worth rushing out for.

Now, here’s where it gets interesting. Tuesday the 28th of July is the standout. The afternoon brings a solid 6 ft SW swell with a cross-offshore breeze from the SW. The wave energy is massive at 1732 (strong), and the report says it’s excellent for experienced surfers. This is a proper, powerful groundswell, and the river mouth setup will handle it well. Be aware, at 6 ft, it’s getting a bit too big for beginners.

Wednesday the 29th of July is the other absolute gem. The morning is glassy – flat calm with a 5 ft SW swell and a 16-second period. Wave energy is still strong at 1250. This is the pick of the whole forecast. Clean, powerful, and lined up. The afternoon holds clean with a light offshore breeze too. This is the day you point the car towards the rivermouth.

After that, the swell starts to fade. Thursday the 30th has a smaller 4 ft set in the afternoon but with a clean cross-offshore wind, making for a fun, smaller session. Friday the 31st and Saturday the 1st of August drop to 3 ft and 3 ft respectively, with clean windows in the afternoons, but the energy is waning fast.

Then we hit a serious dry spell. From Sunday the 2nd of August all the way through to Friday the 7th of August, the swell drops to knee-high (1 ft to 3 ft) and the wind is mostly onshore or cross-onshore, often howling at 18 mph. The wave energy is low (105 to 310), and the quality is poor. This stretch is a write-off for a paddle surfer.

The forecast picks up steam again on Friday the 7th of August afternoon. A new 4 ft S swell arrives with a 15-second period and a light cross-offshore breeze. The energy is back to a moderate 584, and it’s clean. This is promising but a long way out, so keep an eye on the charts.

Saturday the 8th of August afternoon also looks tidy with a 3 ft S swell and a glassy offshore wind, but the energy is dropping. The rest of the weekend into the 9th is back to onshore junk.

So, to wrap it up: your absolute best bets are Wednesday the 29th of July morning (glassy, 5 ft SW) and Tuesday the 28th of July afternoon (clean, 6 ft SW). The rivermouth will be handling proper groundswell, so expect some long lines and a crowd, as it’s often a popular spot. The second week is a gamble, but the 7th of August afternoon has a glimmer of hope.

Rusty.
