The Lowdown
Alright, folks, Rusty here. Let’s chew the fat on what’s coming.
The start of the run is a total dud. Tiny, weak swell with rubbish onshore and cross-onshore breezes. The first few days of September have waves barely a foot and a half, with no energy to speak of – the combined energy numbers are in the low hundreds, meaning the ocean is just about asleep.
Thursday the 3rd and Friday the 4th see the swell nudge up to about 3 feet, but the wind is still a problem, making it choppy and bumpy. The energy numbers climb into the 400s and 500s, but it’s not enough to save it. Saturday the 5th is still marginal.
Then we get a taste of the good stuff. Sunday the 6th of September is the real deal. The swell hits 5 feet from the south, with a 13-second period, and the wind turns cross-offshore from the north. That’s clean. The combined energy jumps to 1122, a proper sign of power. Monday the 7th is even better – 5 feet of south swell, 13 seconds, and glassy conditions in the morning. This is the pick of the forecast. The break is Blackies, a beach and point. While the swell is from the south-southwest, it’s close enough to the optimum westerly direction, and with those clean winds, you’ll be getting some tidy waves. The water temp is about average for the season.
Tuesday the 8th goes bad again with strong cross-shore winds, and from there it’s a long, flat slog. The second week is a whole lot of nothing – tiny waves from 1 foot to 2 feet, weak energy, and poor winds. From the 8th right through the 16th, there’s nothing worth paddling out for.
So, the call is simple: Sunday the 6th and Monday the 7th are your best shots. After that, it’s a waiting game.
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.
