The Lowdown
Imperial
Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for this stretch of coast.
Well, I gotta be straight with you – the next sixteen days are looking pretty grim for a paddle. There’s only one spot that even gets a mention, and it’s a tough one.
We’re starting with a blank run. From now until the end of July, there’s nothing worth chasing. The swell is weak and the wind is all wrong. We’re looking at a stretch of at least four days with no real surf on offer.
The only break that shows up at all is 13th Street. It’s an advanced, inconsistent spot, exposed to the WNW, and it’s usually got a crowd. That’s a lot of caveats right there. The low point of the energy comes in around Thursday the 30th and Friday the 31st, with combined swell energy in the 12 to 22 range – barely a ripple.
We do see a slight bump in energy on the morning of Saturday the 1st of August with a 4ft SSW swell (period 12 seconds) and combined energy of 487. That’s moderate energy, but it’s still marked as poor surf. The morning wind is a light 6 mph onshore breeze from the SW, which is not going to clean it up.
After that, the energy drops back down again. The rest of the first week of August has small, short-period pulses from the SW, with combined energy mostly under 300. The light onshore winds keep things messy. There’s a weak pulse on the morning of Friday the 7th of August with a 2ft SSW swell (19 seconds) and 283 energy, but it’s still not good.
The second week is more of the same. Small, weak swells with onshore winds. The best you could hope for is a morning with a light breeze, but the swell is tiny and the quality is poor. There’s nothing here that’s worth getting excited about.
For a stretch like this, with the break being so inconsistent and the conditions so poor, it’s a real shame. It doesn’t tend to stay this flat for long, but this is a blank run that’s pretty normal for the area when the winds don’t play ball.
Stay patient, check the buoys – I mean, keep an eye on the sky. This one’s a write-off.
Rusty.

Information about the 13th Street Surf forecast
The above surf forecast table for 13th Street provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at 13th Street can be found by selecting the local surf guide option on the grey menu. Our 13th 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 (13th 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 13th 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.
