The Lowdown
Alright, Rusty here again. Let's break down the same outlook for the fellas working in feet and miles.
The water is a warm 73°F right now, which is a solid 6°F warmer than usual for this time of year. That's a real treat for the first day out, feels like a bath.
The honest truth is, the next week and a half is a bit of a grind. The forecast is full of marginal surf and questionable conditions, with a lot of cross-onshore wind and small, weak swells. There's a real gap here with nothing you'd want to paddle out for. The first real chance for a session doesn't show until the morning of Saturday, July 26th, when we see a 4ft SW groundswell with a long 19-second period. The combined energy of all swells directed here is moderate (1164), and with a light breeze from the WSW, it's a cross-onshore wind, so it'll be a bit bumpy. That long period is a bonus for shape, but it might make the waves a bit walled at a beach-and-reef setup like this.
The standout window, and the one I'd circle on the calendar, is the morning of Friday, August 1st. The swell is up to 6ft from the SSW, with a combined energy of 1111 (moderate wave energy). It's a bit of a bigger swell, so definitely for the more experienced crew. The kicker is the wind: light from the SW, which is a cross-onshore. It's the closest we get to something with a bit of push, and the consistency here is consistent, so you can expect a few waves.
The rest of the first week of August looks like it drops right off into poor conditions with building wind, so if you're looking for a paddle, that Friday morning is your best bet. The longer range after that has a few little pulses, but nothing to write home about. It's a waiting game, but that one Friday window has some promise.
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.
