The Lowdown

Alright folks, Rusty here. Let’s break down what’s happening at 15th Street over the next two weeks. It starts slow, real slow. The first few days are all small, weak energy – barely worth waxing the board. The real juice takes its time to arrive.

Right now, the water is way warmer than usual – around 77°F, which is nearly 8 degrees hotter than normal for this time of year. Feels more like summer than early September.

The first decent shot comes on Saturday the 5th. Morning brings a 4ft swell from the S with a 14-second period, building to 5ft in the afternoon. The combined energy jumps up (1209 in the morning, 1402 in the afternoon). Winds are light offshore from the W – glassy conditions in the morning. That afternoon session is looking like the cleanest window of the whole run: small but shapely, and that long period gives it some push.

Sunday the 6th pushes up to 7ft in the morning and 8ft in the afternoon, but the wind goes cross-on from the NNW, messing up the face. It’ll be lumpy.

Now, Monday the 7th is the big one – 10ft from the SSW with a 14-second period. That’s heavy energy (3154 combined). But that’s too big for this spot, and the cross-on wind at 9 mph won’t help. It’s expert-only and messy. Afternoon gets even windier at 16 mph cross-on. Leave it.

The rest of the window, from the 8th onward, is a long dry spell. Swell drops to 5ft and below, period shortens, and winds stay onshore or cross-on. By the 12th we’re down to 3ft with no push. There’s nearly two weeks of nothing after that Monday.

The best bet? Saturday the 5th afternoon. That 5ft S swell, light offshore breeze, clean and consistent. It’s a popular spot when conditions line up, so expect company.

After that, it’s a ghost town. Forecasts change, but right now it looks like a long wait.

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.
