The Lowdown

Alright, this is Rusty again, giving you the same story in feet and miles per hour. It’s gonna be a quiet one at 15th Street for the next couple weeks. The ocean’s just not playing ball for us paddle surfers. There’s a big gap of poor to marginal days ahead, so don’t get your hopes up too soon.

Water temp is a warm 73°, which is way above normal for this time of year – at least you won’t be cold. But the problem is the wind. We’ve got a lot of cross-onshore breeze messing up the waves. Early on, the combined swell energy is moderate to strong (1388 on Sunday morning), with a 6 ft south swell at 14 seconds. But with a 12 mph cross-onshore wind, it’s choppy and lumpy – not great.

Your best chance in the first week is Monday morning, September 7th. The wind goes offshore from the WNW at 9 mph, and there’s still a solid 6 ft swell from the SSW at 13 seconds. The energy is still high at 1237. It’s not perfect, and the surf quality is still marginal, but that early session has the most potential for a few clean waves before the wind shifts onshore in the afternoon.

After that, it’s pretty much a write-off. From Tuesday onward, the swell drops and the wind stays cross-onshore or onshore. The waves get smaller and conditions stay poor. Mid-second week, around September 14th and 15th, we see some very long-period groundswell (18 to 20 seconds), but the wave heights are tiny – just 2 ft to 2 ft. That’s not enough to work with, even with light winds.

The last few days, from September 19th to 21st, show a slight bump: 3 ft to 4 ft from the SW, periods around 16-17 seconds, with light offshore winds. The energy climbs into the moderate range (600-700). But it’s still rated marginal. If I had to call a standout, it’s that Monday morning on the 7th. It’s not epic, but it’s the best of a bad lot. The rest? Honestly, with that strong cross-shore wind on Saturday the 12th, this setup looks more interesting for kiteboarding than surfing.

So keep your expectations low, check the cams, and maybe take a few days off. Forecasts can change, but right now, it’s a waiting game. Rusty out.

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.
