Alright, Rusty here again. Let’s break this down in feet, miles per hour, and Fahrenheit. Looking at the next 16 days for 15th Street, it’s a rough patch. There’s no standout day in the whole run. The surf is tiny and the wind is always working against us. The first few days have the most size, but the quality is still poor, so it’s a long wait for anything good.
It starts on Sunday, July 5th. We’ve got a 2ft SSW groundswell, with a very long period of 18 seconds, pushing a fair bit of energy (448). The wind is onshore from the WNW at 9 mph, so it’s gonna be a mess. The water is a touch warmer than normal at 69°F. Not a session to get out of bed for. Monday and Tuesday, July 6th and 7th, are the same story: 3ft to 3ft SSW swell, with long periods of 16-18 seconds, meaning the energy is moderate (between 529 and 857). But the wind stays onshore, keeping the surface chopped up. The wave comment says it all: marginal at best.
The rest of that first week and into the second is a real struggle. From Wednesday, July 8th, through to Monday, July 20th, the swell bounces between 1ft and 4ft, but the direction shifts and the wind is always cross or cross-onshore, ruining any chance of a clean wave. The energy drops way down, hitting the low 200s and 300s by the end. The wave comments are a constant "poor" or "marginal." There’s a moment on July 16th where the swell hits 4ft from the W, but it’s a short period windswell at 8 seconds, and the wind is cross-shore. It’s a weak, messy setup that would be better for a kite than a paddle.
For a spot that usually has consistent waves, this is a real dud. There’s nothing here worth paddling out for. The early longer period swells *could* have been good with clean wind, but we don’t get it. Keep your wax in the wrapper and watch the forecasts, because it can’t stay this flat for long.
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.
