The Lowdown

Righto, let's have a look at what’s on the cards for 15th Street.

Truth be told, the next couple of weeks are looking pretty grim. We’ve got a bit of swell rolling in at the start, but the wind is just messing it up. Monday morning the 7th sees a 6ft SSW swell with a 13-second period, so there’s some decent energy in the water (1183), but that cross-on NW wind at 9 mph is chopping it up. It’s not all bad news for the brave, but it’s far from clean. The water’s sitting at 73°, which is much warmer than normal for this time of year – that’s nearly 5° above average, so a real treat if you do get in.

Honestly, after Monday it just flatlines for days. Tuesday the 8th is smaller at 4ft and still cross-on, and from Wednesday the 9th onwards we’re looking at tiny, weak swell and poor conditions. There’s a long gap of nothing worth mentioning – a real dry spell from Tuesday through to at least the middle of the second week. The swell stays small, the wind is mostly cross-on or onshore, and the ratings are rock bottom.

Now, later in the window, around Monday the 21st of September, there’s a flicker of hope. We see a 3 to 4ft SSW swell with a 17 to 18-second period – that’s proper long-period groundswell, which is great for shape. The wind goes light and offshore (on) from the WNW, which is a big positive. The combined energy (733) is moderate. This is the standout of the whole outlook, but it’s a long way off, so treat it with caution. 15th Street is exposed to the WSW, and this swell is coming from the SSW, so it’s not a perfect match, but with that long period, the point and reef sections might just focus it up nicely.

A word about the place: 15th Street is a beach and reef setup that is consistent, so it’s a reliable spot when the conditions align. Crowds are often here, so don’t expect a quiet one if it does come together.

For the rest of that second week, there’s a persistent run of light offshore winds and a consistent background of 2ft to 3ft SSW swell with very long periods (15-19 seconds). Nothing big, but the clean wind and those long lines could make for some fun, small-scale surfing at the better reef breaks. It’s more of a patient surfer’s game.

So, bottom line: the best bet is that Monday the 21st. Everything before that is a write-off unless you’re desperate. Keep an eye on the forecasts as we get closer.

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.
