The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming our way for 15th Street.

Honestly, it’s a pretty grim run for the next couple of weeks. Wind is almost always onshore or cross-onshore, and the wave heights stay small. There’s a lot of energy in the water at times, but it’s not translating into anything rideable. The first few days are a write-off, with poor surf conditions and light winds from the west just messing up what little swell there is. We’re looking at a gap of poor conditions stretching from the 5th right through to the 13th of August.

The water is sitting at 77° with a massive anomaly of 9°, so it’s much warmer than usual for this time of year.

The first time we see anything even close to worthwhile is on the morning of Thursday, 14th August. The swell picks up to 3 ft from the SSW, with a period of 18 seconds - that’s a solid groundswell, and the wind is light and onshore from the west. The combined energy of all swells is moderate (688). It’s still only marginal, and the tide could be a factor, but it’s the first sign of life. The Friday the 15th continues that little trend, with a 3 ft SSW swell, still 16-second period, and energy climbing to 742. The wind stays onshore though, so it’s not clean.

The best on offer across the whole 16 days is Saturday morning, 15th August. You’re looking at a 3 ft swell from the SSW, with a 16-second period - that’s decent groundswell. The combined energy is strong (742). The wind is a light 9 mph from the west, which is onshore, but it’s a light breeze so it’s not trashing it completely. It’s still marginal surf, but if you’re desperate, this is the window. It’s a beach and reef setup, and it’s consistent, so waves will be there. The crowd situation means you’ll have company - it’s listed as often busy, so expect a few heads out.

For the rest of the run, through to the 20th, it’s back to small, poor surf with onshore flow. The swell stays under 3 ft and the period drops back, so don’t get your hopes up.

This is a stretch where the wave quality is just not there. It’s a beach and reef break, so with the small, onshore stuff, it’s more of a paddle board or kite session than a proper surf. For the surfer, you’re waiting on that 14th and 15th for the only real chance at a wave.

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.
