The Lowdown
Alright folks, Rusty here. Gotta be straight with ya – this stretch for Isla Vista is a tough one. We're looking at a long, long run of days with very little to get excited about. It’s a beach and reef setup that’s fairly exposed to the west, but the swell just isn't cooperating for paddle surfing for the majority of the next 16 days. The water is sitting at 70° right now, which is much warmer than normal for this time of year, so at least it’ll be pleasant just sitting in the lineup, but you won't be doing much riding.
Right from Tuesday the 18th through to the first week, it’s essentially a write-off. We’ve got tiny dribbles of south-southwest swell mixing in, never cracking 3 ft, and what’s there is so weak the combined energy barely gets into triple digits (260). The wind is mostly light, but it's onshore or cross-onshore, messing up what little shape there is. You’ll see a brief blip of short-period west-northwest windswell around the 22nd, but still under 3 ft and too crumbly. Honestly, this whole first week looks more interesting for a kite surfer than a paddle surfer given the wind and small, poor-quality waves; for us, it's a massive gap of nothing.
Things get a tiny bit more interesting heading into the second week. There’s a pulse of longer-period groundswell from the W on the 24th pushing to 5 ft (293 energy), but it’s that short 6-second period, which means gutless and won’t hold up well at this spot. The 28th of August morning shows a glimmer, with the combined energy jumping to 298 and a 3 ft swell from the WNW at 8 seconds, coupled with light offshore wind from the WSW. The break gets a 1 out of 10, and it's only described as marginal, but with those light offshores, it could offer a few clean, rideable waves if you’re desperate. But don’t expect much.
The only real standout in this whole outlook comes right at the end, on Wednesday the 2nd of September. The morning has a 3 ft WNW swell with an 8-second period hitting 281 energy under a light cross-onshore breeze. Not perfect, but it’s still clean enough. The afternoon is where it's at though – the swell bumps up to 5 ft from the WNW, combined energy hits 404 (moderate), and the wind swings offshore from the SW. It’s still a short-period 6 seconds, so it'll be a bit on the dumpy side for a beach and reef break, but that’s the most power and best conditions on offer for the whole 16 days. It’s for the more experienced crew though; 5 ft with that period can be punchy. If you’re an intermediate or above, that’s the window to look at. Everything else is a pass.
Chin up – when it’s this flat for this long, the next change is almost always on its way.

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