The Lowdown
G’day, Rusty here. Let’s have a look at what’s cooking over the next couple of weeks for La Isla. It’s a reef and point setup, so it’s got that natural shape that loves a long-period groundswell.
Right now, the water temp is sitting at 70.9°F – that’s much warmer than normal for this time of year, a solid 8.5°F above the long-term average. You’ll be in boardies or a light spring suit, no worries there.
The first surf worth paddling out for is actually Sunday afternoon, July 26th. The swell is a clean 2.6 ft from the SW, but it’s got some serious grunt – a period of 18 seconds, which is very long-period groundswell. That’s pure energy, and it’ll wrap beautifully down the point. Winds are light and cross-off at 9.3 mph, so the faces will be clean. The combined energy is moderate at 839. It’s not huge, but it’s quality. Crowds are listed as “often,” so expect a few locals out, but for a point break with that kind of period, it’s worth jostling for a spot.
Monday, July 27th, the swell builds. Morning sees 4.3 ft from the SW at 17 seconds, with a light cross breeze at 6.2 mph. That’s a proper groundswell – the wave energy jumps to 1160 (moderate). The afternoon bumps to 5.2 ft, same direction, 16-second period, and the energy climbs to 1393. Still cross winds at 9.3 mph, so it’s a bit lumpy but rideable. This is the pick of the first week – the bigger swell, good direction, and the point will handle that long period beautifully.
Tuesday, July 28th, holds steady at 4.9–5.2 ft, SW swell, 15-second period. Morning winds are light and cross at 6.2 mph, energy at 1219. The afternoon is similar. It’s consistent, but the wind is more cross than offshore, so the surface isn’t glassy. Still, a solid session.
Things start to drop off a little from Wednesday, July 29th, through to the end of the month. Swell hangs around 4.3–4.9 ft, but the period drops to 12–13 seconds, and the combined energy slides from 1000 down to 363 by Friday, July 31st. Winds stay light, mostly cross or cross-off, so it’s clean but the juice is fading. Not a standout.
We hit a bit of a lull from Saturday, August 1st, through to Monday, August 3rd. Swell is 2.6–3.9 ft, period 11–14 seconds, energy in the 400–500 range. The wind is light and cross, so it’s not terrible, but it’s definitely a smaller, more relaxed vibe. Nothing to get excited about – a flat spell for a few days.
Then, on Tuesday, August 4th, things fire up again. The afternoon session is the one to watch. Swell jumps to 5.9 ft from the S, period is short at 8 seconds, but the energy is solid at 690 (moderate). The wind is cross-off at 9.3 mph, and the wave comment says “expect very good surf conditions.” At 5.9 ft, this is getting into the solid range – it’s a bit much for beginners, but for the advanced crew at La Isla, it’s a ripper. The short period means it’ll be a bit more punchy and less drawn-out, but the point will handle it.
After that, from Wednesday, August 5th, through to Friday, August 7th, the swell settles back to 3.0–4.3 ft, SW direction, with periods of 14–18 seconds. Energy sits around 780–1026. Winds are light, mostly cross or cross-on, so it’s clean but not spectacular. Not a standout.
Saturday, August 8th, is a write-off – poor surf conditions, 0 rating. Swell at 3.6 ft but the energy is weak at 430. Don’t bother.
Sunday, August 9th, picks up again. Sunday afternoon is the best of the second week. Swell is 3.0 ft from the SW, 12-second period, but the combined energy is 513 (moderate). The wind is light cross-off at 6.2 mph, and the wave comment says “expect very good surf conditions.” It’s a clean, fun little wave – not huge, but quality.
Monday, August 10th, wraps it up with 3.3 ft from the SW, 14–15-second period, energy around 650–727. Wind is light cross, so it’s a clean, mellow finish to the forecast.
The standout sessions are Monday afternoon, July 27th (5.2 ft, SW, 16-second period, 1393 energy) – that’s the biggest, most powerful swell with great direction for the point. And Tuesday afternoon, August 4th (5.9 ft, S, 8-second period, 690 energy, “very good” conditions) – it

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