The Lowdown
Alright, let’s get into it. 15th Street is a beach and reef setup, consistent, and it’s exposed to the swell. The water is running at 73°F which is much warmer than normal for this time of year – you’ll be in spring suits or maybe even a skin if you’re brave.
Right now, there’s barely a pulse. The first few days are a write-off. Thursday the 16th through Saturday the 18th, we’re looking at tiny 2ft to 3ft SW swell mixed with a cross or cross-on wind. The energy is weak (259 to 489), and the conditions are poor. Honestly, not worth paddling out. You’ll be sitting there waiting for nothing.
Sunday the 19th morning, things start to get interesting. The swell jumps to 5ft from the S, with a period of 13 seconds, and the energy hits 1459 – that’s moderate-strong. The wind is light cross-on from the WSW, which is workable. It’s still labeled marginal, but that’s the first real sign of life. The afternoon sees 6ft from the SSW, but it’s onshore and breaking straight, so keep it to the morning session if you’re keen.
Monday the 20th through Wednesday the 22nd, the swell drops back to 3ft to 4ft. The wind is mostly onshore or cross-on, and the energy is moderate (614 to 808). These are marginal days at best. You might get a few, but it’s not going to be memorable.
Now, Thursday the 23rd and Friday the 24th, the swell builds again. Thursday afternoon sees 5ft from the S, and Friday morning hits 5ft from the S, both with moderate to strong energy (1156 and 1657). The wind is cross-on, so it’ll be a bit bumpy, but there’s enough push for a longboard or a funboard. Friday afternoon actually shows a cross-shore wind from the SSW, which is a touch cleaner, and the swell is 5ft from the S. That’s probably the best window in the first week.
Saturday the 25th morning, the swell drops to 3ft but the period is a very long 21 seconds from the SSW. The energy is strong (1409), but with that kind of period, it’ll be fat and straight at the beach break. Better suited for a point or reef, but at 15th Street, it’ll be a slow, walled-up mess. The wind is onshore, so it’s marginal.
The second week, from Sunday the 26th through to the end of the month, the swell stays in the 3ft to 4ft range from the SSW, with periods between 14 and 19 seconds. The energy is mostly moderate to strong (608 to 1319). The wind is often onshore or cross-on, so the quality is going to be marginal at best. The standout here is Tuesday the 28th morning – 4ft SSW, 17 seconds, light onshore wind, and energy of 1091. It’s the most consistent-looking morning in that stretch, but still not a classic.
The very last few days, the 30th and 31st, the swell fades to 3ft to 3ft. The energy drops, and the wind is light onshore. It’s fizzling out.
Overall, the best bet is Friday the 24th afternoon, with that 5ft S swell and a cross-shore wind. It’s not perfect, but it’s the cleanest of the lot. The Sunday the 19th morning is also a shout if you want to get on it early. Don’t expect a lot of size or power – this is a marginal run for 15th Street.

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.
