The Lowdown
Right off the bat, I gotta be straight with you: the next couple of weeks are looking pretty grim for any real surf action at Blackies. We've got a solid run of small, weak swell and onshore winds that are just going to keep things messy. It’s a tough stretch, and I’m not seeing much to get excited about for a while.
Looking at the opening days, Monday the 14th and Tuesday the 15th are basically flat. We’re talking tiny 0.4m to 0.5m of SW swell, with a long 18-second period, but the wind is cross-onshore and the surf is just going to be chopped up. The energy is weak (200 to 254 in the combined energy). It’s not going to be worth paddling out for anything more than a float.
The middle of the week, the 16th through the 19th, sees a slight bump in size to 0.7m to 0.8m, but the wind stays onshore or cross-onshore, and it’s still messy. The period drops to 15 to 18 seconds, which is decent, but the quality is poor. On the 17th and 18th, there are a few marginal windows when the wind lightens, but it’s still mostly cross-onshore chop.
The following weekend, the 20th and 21st, the swell holds around 0.8m to 0.9m, and the energy gets a bit more punch (up to 477), but it's still a cross-onshore mess. It’s not the kind of surf that will have you rushing down there. The water is a warm 23°, which is much warmer than normal for this time of year—that's a nice bonus.
Things start to fade again from the 22nd through the 24th, dropping back to 0.7m to 0.8m with the period shrinking to 14-16 seconds. The wind stays on the bad side of things, keeping it choppy and weak.
The last few days of the forecast, from the 25th through the 29th, are more of the same. We’re looking at 0.5m to 0.7m of weak, short-period swell and constant onshore flow. There’s one day, the 29th, where the wind is light, but the swell is only 0.5m and it's still cross-onshore. It’s just not happening.
Honestly, for the next 16 days, Blackies is not the spot. The break is inconsistent, and with this small, short-period swell and prevailing onshore winds, it’s going to be a lot of work for not much reward. There are no standouts, no epic windows. If you’re desperate, maybe a dawn paddle on the 17th or 18th when the wind is lightest, but don’t expect much. This looks like a good stretch to work on your pool tan or get some other things done. The surf will come back eventually—it always does. But for now, I’d sit this one out.

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.
