The Lowdown
Hey, Rusty here. Let’s talk about what’s in the water for 15th Street.
The next 16 days are a bit of a slow start, a quick peak, and then a long, flat stretch. It’s not gonna be pumping, but there are a couple of windows if you know what you're doing. The water temp is 74°F, which is about 7°F warmer than average for the time of year. That is seriously warm water.
We kick off on Saturday, July 25th, with small, chest-high waves at about 3ft from the SSW. The swell period is pretty long at 21 seconds, so there’s a lot of deep water energy, but the combined energy is moderate at 924. The wind is a light cross-on from the WSW, so the surface won't be perfect. Not a great day.
Sunday the 26th and Monday the 27th see the swell build slowly. We’re at 4ft to 4ft from the SSW, with the period still very long at 18-19 seconds. Combined energy climbs to 977 and then over 1000. The wind stays light and cross-on, keeping things a bit messy. You’ll get waves, but they’ll be a little lumpy.
Tuesday and Wednesday, the 28th and 29th, are more of the same. Swell hangs around 4ft to 5ft from the SSW. The wind picks up, especially Tuesday morning with a moderate breeze making it choppy. Combined energy is strong, near 1300. Nothing special.
The best pulse arrives on Thursday, July 30th. Swell builds to 6ft from the south in the morning, hitting 7ft by the afternoon. The combined energy jumps to strong levels at 1418 and 1648. The period is a solid 15 seconds – groundswell. The light cross-on wind is still a bummer, but this is the best size and power of the whole forecast. That size is not for the groms.
Friday, July 31st, the swell peaks around 7ft from the south in the morning. Energy is strong at 1914. The wind switches onshore from the W, making it lumpy. With that much swell and onshore wind at a beach and reef setup, it's looking like a better day for kite-surfing than paddle-surfing.
Then it’s all downhill. By Saturday, August 1st, we’re back to 5ft, and by Sunday, August 2nd, it’s tiny 3ft with weak energy (277). From August 2nd all the way to August 9th, it’s a big fat blank. A full week of poor surf, waves under 2ft, and combined energy struggling to hit 300. The wind is light and onshore or cross-on, so not even a longboard will get you going. This kind of flat spell isn't unusual for this area.
So, bottom line: your best bet is Thursday, July 30th, and maybe the morning of Friday, July 31st. After that, you’re looking at a week off. Make the most of that window.
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.
