The Lowdown

Alright folks, Rusty here. Let’s take a good hard look at what’s comin’ our way.

Right off the bat, I gotta be straight with you: the next week and a half is a bit of a heartbreaker. We’re looking at a long stretch of poor surf conditions, with barely a whisper of rideable waves. The first real glimmer of anything worth paddling for doesn’t show up until Thursday the 13th, and even then it’s a marginal call. From now until the 12th, you’re better off fixing a ding or making friends with the wind.

15th Street is the only game in town, a consistent beach and reef setup that’s exposed to the swell. The water’s about average for this time of year, so no surprises there. The trouble is, the wind is mostly onshore, swinging from WSW to WNW, and the swell is small and weak. We’re talking a bumpy 2 ft to 2 ft from the SSW and SW, with a long period (13-18 seconds) that suggests real energy moving through, but the wind just kills it. The combined energy is weak to moderate, ranging from 324 to 471, but it’s all messy.

Thursday the 13th and Friday the 14th offer a tiny bit of hope. Mornings with a light breeze and a 2 ft to 3 ft SW swell (16-18 second period) might be just about surfable if you’re desperate. The energy picks up a bit on Friday afternoon, hitting 704, but it’s still marginal. I’d call it a one-star day at best.

Saturday the 15th morning sees a 3 ft SSW swell, and the afternoon bumps up to 4 ft with the same direction. The wind stays onshore, though, so it’s going to be lumpy. The combined energy climbs to 720, but the quality just isn’t there. Sunday the 16th is more of the same – 4 ft in the morning, dropping off again.

Then the bottom falls out. From Monday the 17th all the way through to Sunday the 23rd, it’s a grim run of poor surf with waves never getting above 3 ft. The wind is relentless, onshore or cross-onshore, and the swell is all over the place. You’ll see a 4 ft W swell on Saturday the 22nd, but with a short period of 8 seconds, it’s going to be weak and unorganized.

The only standout in this whole 16-day window is a bit of a long shot, but it’s the best we’ve got. Look at Tuesday the 25th – the morning shows a 3 ft SW swell with a long 18-second period, and the wind is coming from the south at 12 mph, which is a cross-shore breeze. The combined energy is a solid 587, and it’s the first time we get a “cross” wind state, not onshore. It’s still marginal, but for this region, that’s the closest thing to a clean window we’ll see. The afternoon goes back to poor, but that Tuesday morning is your best bet.

Highlight: If you’re itching for a session, pencil in the morning of Tuesday, August 25th. The 3 ft SSW groundswell with that long period should wrap in okay, and the cross-shore wind will keep it cleaner than anything else. Expect crowds at 15th Street, as it’s often busy. It’s not a classic, but it’s the only real chance in the whole outlook.

Honestly, for the rest of the time, the setup is so wind-affected and small, this break might be more interesting for the kite surfers than a paddle surfer. We’ll just have to wait and see if the forecasts change.

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.
