The Lowdown

Alright, Rusty here. Let’s talk about 15th Street.

Right now, the outlook is a bit of a slow burner. We’re staring down the barrel of a tough first week with a lot of days where the surf just isn't working. The swell is there, but it’s mostly small, and the wind has been a real pain, blowing onshore or cross-onshore just about every day. For the first few days, from Tuesday the 1st right through to the middle of the following week, it’s mostly a write-off. You’re looking at poor surf conditions with swell heights barely breaking 3 ft, and the wind is just ruining any chance of a clean face. It’s frustrating to watch.

We finally get a glimmer of hope on the morning of Tuesday, the 8th of September. This is the standout. The swell is a solid 6 ft from the SSW, with a period of 12 seconds – that’s some real groundswell energy. The combined energy is a strong 1075, which is moderate to strong, and you’ll feel that push. But the real kicker is the wind: it’s blowing from the SSE at 9 mph, giving us a clean, cross-offshore breeze. The report says it’s clean, and for experienced surfers, it’s looking excellent. That morning is the window. The water temp is about average for this time of year, so a 3/2mm steamer will be fine.

After that, the swell drops off a cliff again. The rest of the second week is back to small, weak swells and onshore winds. The 15th Street is a consistent spot, but it’s not going to save us this time. The whole run from the 9th onward is just poor to marginal, with the odd tiny bump. Don’t get your hopes up for the second week, it’s a real flat spell.

The one true highlight is the Tuesday morning of the 8th at 15th Street. That’s the day to circle. It’s a beach and reef setup, and with that 6 ft groundswell and clean offshore wind, it’ll have some punch. The only downside is that with a spot this good, you can expect to see a few other people out there, as it’s often crowded.

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.
