The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’ve got a bit of a tricky run ahead for the next couple of weeks, so let’s keep it real.
The overall picture is a slow start, with a few pulses of long-period groundswell but the conditions are often fighting us. The water is sitting at a very unusual 74°F, which is much warmer than normal for this time of year – feels like summer hung around.
The first real chance to get wet comes on Saturday, September 5th, but it’s a bit of a tease. Blackies is seeing a 3ft swell from the SSW with a very long 16-second period, pumping in moderate energy (436). The wind is a light cross-on from the west, though, so it’s going to be a little bumpy. You’ll find some clean lines if you’re patient, but the tide could be a factor. It’s not the best of the run, but it’s the first one on offer.
Sunday the 6th looks a bit more interesting. The swell bumps up to 5ft from the south, still a solid 14-second period, and the energy is strong (1019). The early morning shows a light cross-offshore wind from the north, which should clean things up nicely. This is probably the standout for the first week. It’s an intermediate-level wave, but that long period means it’ll be a bit more powerful and have longer lulls between sets. The point setup at Blackies should handle it well.
By Monday the 7th, the swell holds at 5ft, but the wind swings cross-shore and then cross-on in the afternoon, making it choppy. The rest of the first week into the second week is a downhill slide. The swell drops off steadily, going from 4ft on Tuesday down to 1ft by the following Monday. The wind is mostly cross-on or onshore, and the energy drops into the weak two-digit range (107) by Sunday the 13th.
There’s a notable gap of poor conditions from about Tuesday the 8th all the way through to Friday the 18th. That’s a solid 10-day stretch of tiny, messy, or onshore slop. Not worth paddling out for.
Now, looking further out, there’s a glimmer on Friday, September 18th. We’ve got a 2ft SSW swell with a very long 20-second period, and the energy is building back up (309). The wind is light and offshore from the SSW in the morning. Saturday the 19th and Sunday the 20th also show similar 2ft swells with light offshore winds. This is a promising long-range signal, but it’s a week and a half away, so don’t book the day off work just yet. The very long period means the waves will be clean and lined up, but at that size, it’s really for the longboard or a fun fish. The inconsistency of Blackies also means you might be waiting a while between sets.
So, to wrap it up: your best bet is Sunday morning, September 6th at Blackies. The 5ft south swell with the clean morning wind is the pick of the bunch. The second week offers a few tiny, clean windows from the 18th onwards, but it’s a long wait for not much push. Hang tight, Rusty.

Information about the Blackies Surf forecast
The above surf forecast table for Blackies provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Blackies can be found by selecting the local surf guide option on the grey menu. Our Blackies 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 (Blackies) 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 Blackies 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.
Blackies is 1 km (1 miles) from the city of Newport Beach. If you plan a vacation in Orange County, look for hotels and other accommodation in Newport Beach. Newport Beach has rooms for a wide range of budgets as well as car hire and transport links.
