The Lowdown
Alright, grab a coffee and listen up, this is Rusty.
To be honest, mate, it’s a pretty flat run for the next couple of weeks. We’ve got a solid gap of nothing worth paddling out for right from the start. You’re looking at a stretch of days where the surf is just too weak to get excited about.
Looking at the only real option on the table, 13th Street. This spot is an advanced wave that is inconsistent, which means it doesn't work often. The water temp here is about average for this time of year. The best chance we see in the whole forecast is on the morning of Friday the 7th of August. That morning, we get a tiny 2ft swell from the SSW with a very long 19-second period, which is a true groundswell. The combined energy is only in the moderate range (300), so it’s not packing a punch, but that long period will give it some shape. It’s also glassy with a light breeze, so it’ll be clean. For an inconsistent spot, this is the standout, but honestly, it's still pretty marginal.
After that little flicker on Friday morning, it drops straight back into poor conditions. The rest of the week and into the second week is a dead zone of tiny, weak swells under 3ft. The energy readings are consistently weak to moderate (91 to 427), and the wind is either onshore or cross-onshore, adding to the chop. There’s nothing else worth highlighting. This break simply doesn't have the goods for a proper surf during this period.
Rusty.

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.
