The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way. I gotta be straight with you—this is a tough stretch. We’re looking at a full 16-day window, and honestly, there isn’t a single day that I’d call a standout. The surf is small, the wind is mostly onshore or cross-onshore, and the conditions never really come together for a proper session at Blackies.
The first day with any surf to mention is Sunday the 13th of September. We’ve got a small 2 ft swell out of the southwest, but the combined energy is only moderate (200). The wind is light and onshore from the WSW, and the whole setup is marked as poor. The water temperature is 72°, which is a whopping 5° warmer than normal for this time of year—very unusual, but with waves this weak, you’re just floating in warm water.
Monday the 14th through Tuesday the 15th sees tiny 1 ft to 2 ft groundswell with periods up to 18 to 20 seconds. That long-period swell from the southwest could have some shape, but the wind is cross-onshore or onshore all day, so it’ll be choppy and messy. Energy stays in the low-to-moderate range.
By Wednesday the 16th and Thursday the 17th, the swell bumps up just a touch to 2 ft to 3 ft, and the energy finally climbs into the moderate range (374 on Wednesday morning). But again, the wind is cross-onshore, so the surface stays bumpy. Thursday morning is described as marginal, which is about as good as it gets. Still not something you’d paddle out for.
From Friday the 18th right through to Saturday the 26th of September, it’s the same story. Swell hangs around 2 ft to 3 ft with moderate-to-strong energy (peaking at 538 on Monday the 21st afternoon), but the wind just won’t cooperate. Light cross-onshore breezes are the best we get, and even then, the wave comment stays poor or marginal at best. The swell direction is southwest through south-southwest, and with periods often around 15 to 19 seconds, this is proper groundswell—but it needs clean conditions to be any good at a spot like Blackies.
For the last couple of days, Sunday the 27th and Monday the 28th, the swell drops back down to 1 ft to 2 ft. Monday afternoon has a pretty solid energy reading of 485, but the wave comment is still poor.
So here’s the bottom line: there are no real standouts in this 16-day run. The surf is always too small, too onshore, or both. Blackies is inconsistent at the best of times, and this stretch is a long blank run. It won’t stay poor forever—forecasts can change—but for now, I’d leave the board at home.
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.
