Alright, Rusty here, let's get into it.
First off, the water is sitting at 71°F at 15th Street, which is a full 5°F warmer than usual for this time of year. That's a real treat, and it makes the small, clean conditions we've got on the horizon a bit more bearable.
Let's be straight with you: the first week is a grind. From Thursday 9th July right through until the middle of the following week, the surf is small and the quality is average at best. We're looking at waist-high waves, around 2ft to 3ft, from the SSW, with a period that's fine but nothing special. The wind is a constant cross-onshore for most of it, keeping things a bit bumpy. There's a spot of light offshore wind on the morning of Saturday 11th, and again on Sunday 12th and Monday 13th, but even then the swell is too weak to get excited about. The combined energy sits between 228 and 648 (moderate), which tells you it's just not got the oomph for a proper session. This is a real quiet spell, and you'd be better off waiting.
The real story, the only standout in this whole 16-day window, is the weekend of the 18th and 19th of July. On Saturday 18th, we see a jump in size. The morning brings 3ft from the S, but it's the afternoon where things get interesting: 5ft from the SSE with a period of 16 seconds, and the combined energy jumps to 1523 (strong). The wind is light offshore from the W, which is a major positive. This is a proper clean groundswell, and at that size, it's still manageable for most.
Then Sunday 19th is the pick of the lot. The swell builds to 6ft from the S, with a period of 14 seconds and a combined energy of 1579 (strong). Again, we have light offshore wind from the SW in the morning. This is chest to head-high, powerful surf. The only catch is the crowd situation – 15th Street is often busy, so expect company. The wind is cross-onshore by the afternoon, so get out early. This is the one to aim for.
After that, the swell drops back down to the 3ft to 4ft range for the rest of the week, with the wind turning cross-onshore again. It's back to the same old story.
So, to sum it up: the first week is a write-off, save for a few brief windows of clean but tiny surf. Your one and only proper shot is the weekend of 18th and 19th July, with Sunday 19th morning being the absolute best on offer. The rest is just a waiting game.
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.
