The Lowdown

Alright, Rusty here. Let's talk about what's on the table for 15th Street over the next couple of weeks.

Right off the bat, I gotta be straight with you – this isn't a screaming forecast. We're looking at a long stretch of small, often messy surf. The first real opportunity to even consider a paddle won't come until Wednesday, September 16th, and even then, it's a marginal call.

The pattern is stubborn: mostly small southwest swells, with periods that are all over the place. We've got some long period stuff sneaking in, but the energy is moderate at best, with combined swell energy kicking around the 300 to 500 range – nothing that's going to get your heart racing. The biggest issue is that the wind is mostly cross-onshore, which is just no good for a spot that's as exposed as this one. It's going to be choppy and bumpy.

Now, for the best of a pretty average bunch, you'll want to look at the later part of the first week and into the second. Monday the 21st of September into Tuesday the 23rd sees a slight uptick. The swell bumps up just a touch to around 3ft to 4ft, still from the SW, with that combined energy climbing to 669 and 736 – still moderate, but heading in the right direction. The wind stays lighter, sometimes offshore from the W, so the surface could clean up a little. This is your best bet for a wave, but keep the expectations low. It's still small.

Honestly though, nothing here is a standout. The cycle just keeps pumping out the same story: small swell, mediocre conditions. For a consistent spot like 15th Street, this is a bit of a bummer, but it happens. The water temperature is a story in itself on the 13th of September – it's reading a whopping 73°, which is 6° above normal for this time of year. That's very unusual, so expect some surprisingly warm water for your trouble.

The long-range stuff around the 27th and 28th of September shows a big long-period swell (20-21 seconds) but the height is a tiny 2ft to 2ft. That's the classic case of a lot of energy that never really stands up. It's a tease.

All in all, if you're desperate, keep an eye on the 21st to the 23rd of September. Otherwise, I'd wait and see if things change. This is one of those stretches where the forecasts can flip, so don't give up hope entirely, but be ready for a lot of flat and blown-out afternoons.

Rusty.

Information about the 15th Street Surf forecast

The above surf forecast table for 15th Street provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at 15th Street can be found by selecting the local surf guide option on the grey menu. Our 15th Street 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 (15th Street) 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 15th Street 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.
