The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards.

To be straight with you, the next few days are a write-off. We’ve got small, weak swells and the wind is all wrong – mostly cross-onshore, making everything choppy and messy. There’s really nothing to get excited about until mid-week.

Now, buckle up, because Wednesday the 16th is where things start to look interesting. 15th Street’s gonna wake up. We’ve got a clean 3 ft swell rolling in from the SSW with a period of 17 seconds – that’s proper long-period groundswell, so expect some real push and shape. The wind swings offshore from the W and it’s light at 6 mph. That’s glassy conditions, folks, and at a spot like this, that’s pure magic. The wave energy is ramping up too, hitting 525 (moderate energy). The water’s sitting at a balmy 74°, which is much warmer than normal for this time of year, so you won’t need a thick suit.

This is the standout. Wednesday morning and afternoon both look solid, with the morning offering a touch more quality. It’s not huge, but for clean, lined-up waves with that long-period push, this is the best we’re going to see. Keep in mind that with a period pushing 17 seconds, the sets will be spaced out – plenty of time to get back out the back. This is a consistent break and can get crowded, so expect some company on the peak.

After Wednesday, we drift back into a marginal zone. Thursday and Friday still have some offshore wind and a little waist-high swell, but the energy drops and the conditions are just a bit “meh.” By the following week, the onshore creep comes back and it’s more of the same – small and choppy. A bit of a bummer after that one good day.

So keep your eyes on Wednesday 16th. That’s your window. Don’t sleep on it.

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.
