The Lowdown
Alright, this is Rusty. I gotta be straight with you right from the start – the next 16 days around Isla Vista look like a tough stretch. We’re staring down a long gap with very little to get excited about. The first real potential comes on Tuesday the 18th, so from now until then, it’s pretty much a write-off for anything worthwhile.
We kick things off Thursday the 13th with nothing. Tiny, weak, poor conditions with a light cross-onshore wind ruining what little is there. This flat, choppy pattern sticks around through the weekend and into Monday the 17th. The combined swell energy is weak, with readings in the 200s range showing there's just no juice in the water.
Now, on Tuesday the 18th, the pattern shifts a bit. We get a bump in size from a WNW swell, coming in around 3.5ft to 4.5ft, but the period is a short 8 seconds. It’s a wind swell, not a groundswell, so it’s gonna lack punch and shape. The wind is still light and onshore, so while it’s not howling, it's not clean. The energy reading (386) is moderate, but the wave comment says "marginal." It might be rideable for someone who’s been jonesing, but it’s not a standout. This sloppy, marginal surf from this same wind swell pattern continues into Wednesday the 19th.
After that, from the 20th through the 25th, we drop back down into a poor, tiny lull. Swell heights drop below 1.5ft, the energy falls away (as low as 88 on the 22nd), and there’s just nothing to work with. A couple of the days have those long-period (19 second) SW groundswells showing on the 23rd, but they’re so small at 1.3ft that they’re invisible. It’s honestly a bit heartbreaking to see a nice 19-second period with zero size.
Even when we look to the end of the period, Friday the 28th, it’s another weak WNW wind swell at 3ft and an 8-second period. The wind is onshore again.
To be fair, the water temp is about average for this time of year, so if you’re just wanting a swim or a paddle, it’s fine.
In short, there is no true highlight or standout in this whole 16-day window. The best chance to get wet on a foamie will be the morning of Tuesday the 18th or Wednesday the 19th for the slightly bigger, albeit short-period, wind swell. Everyone else, park the boards, check back later – forecasts can change, it can’t stay this flat forever.

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.
