The Lowdown
Alright, let’s have a look at what’s cookin’ at 15th Street.
The first week and a half is pretty grim. From Saturday the 18th through the middle of that following week, it’s just small, weak, and chopped up. Swell is barely breaking a foot or two, wind is onshore or cross-onshore, and the wave energy is pretty puny. Not much to write home about.
Things start to turn around a little around Friday the 24th. We start seeing some swell in the 4-5 ft range out of the south, with a period around 13 seconds. The combined swell energy jumps up into the strong range (1293). The morning has a light cross-onshore breeze – workable, but not perfect.
Your best shot at something halfway decent is Saturday the 25th in the morning. The swell hits about 5 ft (1.6m) from the SSW, period 14 seconds, with very strong energy (1519). That’s pushing into the big stuff, so it’s really for the experienced crew. The wind is light onshore, so it won’t be perfect, but it’ll have some push and power. That’s the one standout window in the whole 16 days.
From there, it’s a long slog of “meh.” The wave energy stays strong right through the end of the month, but the wind stays mostly onshore or cross-onshore. The swell direction swings from SSW to SW, and periods run anywhere from 13 to 19 seconds. There’s plenty of raw power in the water (strong to very strong, 1036–1784), but without a clean offshore wind, it’s going to be a bumpy, lumpy mess at the beach and reef.
The last few days – from the 30th on – fizzle out. Swell drops back down to 2-4 ft, the energy goes back to moderate, and the wind stays light but still onshore. By the 1st and 2nd of August, it’s back to being small, weak, and not worth the paddle.
So here’s the takeaway: if you’re chasing a wave, Saturday the 25th morning is the one to aim for. It’ll have the size and the grunt, but it’s gonna be crowded, and it’s not going to be glassy. That’s about the best we get this time around.

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.
