Alright, Rusty here. Let’s take a look at what we’ve got coming down the line for 15th Street. To be straight with you, the next couple of weeks are shaping up to be a real patience tester. We’ve got a long, quiet stretch to start, and it’s not until much later that we might see something worth paddling out for.
The water’s sitting at a very unusual 72°, which is a solid 5° warmer than normal for the time of year, so at least you won't need a thick wetsuit if you do go in.
Right now, and for the foreseeable days, the surf is pretty flat and messy. Saturday the 11th has some small 3ft swell from the SSW, but it’s a cross-on breeze from the SW, and the whole thing just feels weak. The swell energy is in the moderate range at 470, but the wave comment says it’s marginal, and honestly, the score reflects that. Sunday the 12th and Monday the 13th are worse, with onshore winds and even smaller waves. There’s a real blank run here for the start of the forecast.
From the 14th through to the 24th, the story doesn't get much better. We’re looking at a string of days where the swell barely gets above 3ft, and when it does, the wind is either onshore or cross-onshore, making for bumpy, unsatisfying conditions. There are a few moments where the period gets long, like a 24-second groundswell on Friday the 24th, but with onshore wind and weak energy, it’s just not coming together. The energy values stay mostly in the 200s to 600s, which is moderate at best, but the wind just ruins it.
Now, here’s where it gets interesting, but you’ll need to wait. Saturday the 25th morning, we see a jump in energy to 979, which is a solid moderate swell. We’re looking at a 3ft swell from the SW at a very long 21-second period. That’s proper groundswell, and with light onshore wind, the setup might start to groom a bit. This is the best-looking window in the whole 16 days, and it's two weeks out, so you’ve got to keep an eye on it. The longer period groundswell like this can break a bit straight at a beach break like 15th Street, but if the tide is right, there could be some clean lines. Consistency is listed as consistent, but with that long of a gap between sets, paddling out should be easier.
The following morning, Sunday the 26th, is also worth a mention. Another 4ft from the SW at 19 seconds and energy at 959. Again, a light cross-on breeze is the wind, but it’s not a deal-breaker. This is your other standout. Both of these days are far out, so take it with a grain of salt, but if the forecast holds, it could be the best we see.
For the rest of the time, if the wind is up and the swell is weak and onshore, this is more of a spot for the kite crew than a classic paddle session.
Keep the faith, the surf will turn. This is Rusty, signing off.

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.
