The Lowdown
Alright folks, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty flat and funky for 15th Street. We’ve got a window that’s mostly junk, but there might be a couple of moments where you can get wet without hating yourself.
The water is sitting at 76°, which is about 8° warmer than normal for this time of year. That’s a seriously unusual warm patch, so at least you won’t need a thick suit.
Right now, it’s not really doing anything. For Saturday the 8th and Sunday the 9th, we’ve got a small SSW swell at 3ft to 3ft, but the wind is blowing on it and it’s just messy. The energy is moderate, around 426, but the quality is poor. You’re not missing a thing.
Monday the 10th rolls in with a bit of a cross-onshore breeze and the surf stays small, around 2ft to 3ft. There’s a slightly longer period SW swell (20s) showing in the afternoon, but the wind is chopping it up. It’s still not worth the paddle.
The middle of the week, from Tuesday the 11th through Thursday the 13th, remains in the doldrums. We’re looking at knee-high waves, mostly poor conditions, and a lot of waiting around for nothing. The swell energy is moderate but it’s just not translating into anything rideable.
Things start to look a little more promising towards the end of the first week and into the weekend. On Friday the 14th and Saturday the 15th, the swell bumps up slightly to 3ft to 4ft, and the energy is building into the strong range, hitting up to 716 on Saturday afternoon. It’s still not clean, with a cross-onshore wind, but there’s a bit more push to it. The period is around 16 seconds, which is a good sign for some better shaped waves.
For the week that follows, from the 16th through to the 23rd, it’s a mixed bag but generally still on the small side. The 16th and the 18th have some 4ft waves, but the winds are on it or cross-onshore. The energy stays moderate for most of it. Towards the end, around the 22nd and 23rd, it fades out again to under 3ft.
Honestly, there’s no true standout session here. If you’re desperate, maybe the Saturday the 15th afternoon looks the most interesting with that bigger push of SSW swell at 4ft, but the cross-onshore breeze will make it challenging. It’s not one for the beginners. This is a stretch where you’d be better off checking the forecast closer to the day, because right now, the pickings are slim.
Signing off,
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.
