The Lowdown
Hey, Rusty here. Look, I’m gonna level with you – it’s a tough stretch ahead for 15th Street (beach and reef). The next two weeks are pretty much a bust for decent waves. We’re looking at a long dry spell, with the first solid chance of anything worthwhile not showing up for over a week.
Right out of the gate, from Thursday the 16th to Sunday the 18th, it’s all poor. Swell is tiny, just 2ft from the SW to SW, with a cross-shore breeze. The water is about average for this time of year. Not even worth paddling out. The combined energy barely scratches 340 (weak), and the wave comment says it all: poor surf conditions.
We finally scrape into something “marginal” by Saturday the 18th afternoon, with a slight bump to 3ft (SW), but it’s still cross-onshore and choppy. This is more kite-surfing weather than proper surfing. The energy gets up to 635 (moderate) but it’s messy.
Now, Sunday the 19th starts to look a bit more interesting, but it’s still not a standout. The swell comes up to 6ft from the S, with a period of 14 seconds. That’s a solid medium-period swell. The combined energy jumps to 1414 (strong). But the wind is onshore or cross-onshore the whole time, which is going to chop it up. For a beginner, 6ft is going to be too much, and the onshore wind means it won’t be pretty.
The best bet, if you’re desperate, is probably the morning of Thursday the 23rd and into Friday the 24th. We’ve got a similar setup – 6ft to 6ft from the S, period around 13-14 seconds. Combined energy is strong (1193 and 1973). But still, that light cross-onshore wind will leave it with some surface texture. It’s marginal, and the “questionable tide” comment makes me think the sandbars might be iffy. This is really only for experienced surfers who know the spot well.
After that, the swell drops back down from the 26th onwards, getting smaller and back into that 3ft to 4ft range with the same cross-onshore wind.
Honestly, the whole 16-day window is grim. There’s no day where the wind cleans up. The best you can say is that from the 19th to the 25th of July, there’s some size (5ft to 6ft), but the quality just isn’t there. Keep an eye on the forecasts – it can change, but right now, save your energy.

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.
