Alright, this is Rusty.
Let's be straight up, 15th Street is not looking like a classic July run. The first few days are a write-off. Most of the first week has miserable conditions, with cross-onshore winds shredding the surface and the swell energy sitting in the weak to moderate range. You'll see the combined energy hovering around 400-500 (moderate wave energy), but the wind just ruins it. The water is about 71°F, which is much warmer than normal for this time of year, so that's a head-scratcher. You'll be sweating in a spring suit, but the surf won't be worth the paddle.
The first real pulse of something interesting shows up on the 19th of July. The combined energy jumps to 1458 (strong wave energy), with a solid 4ft to 4ft South swell. The period is a long 14-16 seconds, which is a proper groundswell. The problem is the wind is still cross-onshore, so the surface will be a bit messy. That said, the size is there, and the energy is real. This is the best on offer in the entire window. It won't be perfect, but it will be the only time you'll get a wave with some grunt.
The 20th of July sees the swell peak at 6ft, pushing into expert-only territory. The combined energy is 1388 (strong wave energy) and the wind looks a little better, switching to a light onshore from the West. Still not clean, but for a beach and reef setup, a 6ft SW groundswell will have some power. After that, it drops off quickly into marginal junk again.
So, to be honest, the only standout is the 19th into the 20th. The rest of the 16-day window is a long, flat, choppy gap. The break is consistent, but the swell and wind just don't line up. For a beginner, the 6ft on the 20th is too big, and the 4-4ft on the 19th is borderline. There's nothing here for the paddler who wants clean, lined-up waves. Honestly, with the onshore winds and the beach setup, this whole period looks more like a kite-surfing window than a paddle-surfing one.
Rusty.

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.
