The Lowdown
Alright, folks, let’s talk Blackies. This is a beach and point setup that’s inconsistent, so don’t expect waves every day. The water is sitting at 72°F, which is much warmer than normal for this time of year – a real treat for the skin.
The first good chance won’t come until August 23rd, Sunday afternoon, but honestly, it’s a write-off. We’re looking at a weak 1ft swell from the SW with a very long 18-second period, but combined energy is a low 270, and it’s cross-on from the west at 12 mph. The surf is poor and choppy. Not worth a paddle.
Monday the 24th is a bit better, but still marginal. The morning has a 2ft SSW swell at 14 seconds, with light onshore wind from the SSW (3 mph). The combined energy is 333, but the forecast says it’s questionable due to tide. The afternoon is poor again.
Tuesday the 25th is more of the same – small, weak, and cross-on. The morning is marginal with a 2ft SW swell, but the afternoon is poor.
Wednesday the 26th shows a jump in size. The morning has 4ft of S swell at 13 seconds, with combined energy hitting 698 (moderate energy). The wind is light cross-on from the south at 6 mph, but it’s still only marginal due to tide. The afternoon is similar.
Thursday the 27th and Friday the 28th are all poor or marginal, with cross-on winds messing up the shape. The swell sticks around 3ft to 2ft from the S/SSW, but the wind is just too onshore.
Saturday the 29th into Sunday the 30th is more of the same – poor conditions with moderate cross-on winds. The swell is around 3ft, but the wind kills it.
There’s a long gap of poor surf through the end of August and into the start of September. Most days are written off with poor surf conditions or are just marginal.
Now, the first real standout appears on Saturday, September 5th. The morning at Blackies is looking clean. We’ve got a 4ft SSW swell (16-second period), combined energy of 593, and the wind is a light cross-offshore from the NNW at 6 mph. The forecast says “expect good surf conditions.” This is the one to circle. The wind will be clean, making for some fun, lined-up waves. It’s inconsistent here, so when it’s on, it’s worth the wait.
After that, Sunday, September 6th morning sees a bigger bump – 5ft from the S (14 seconds) with a very strong combined energy of 1315. The wind is light onshore from the SW at 3 mph. This is getting into the expert zone for size, and the period is still long. It’s marginal, but the energy is huge. The afternoon is 5ft and still marginal.
Monday, September 7th is still solid, with 5ft in the morning, but the wind shifts cross-on, and the surf quality drops off.
So, look, the pick of the whole 16-day window is Saturday morning, September 5th. It’s the only session where the wind and swell truly align for a clean, fun wave. The rest is a lot of waiting for the wind to behave.

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.
