The Lowdown
Alright, let's talk shop. It's looking pretty bleak for Blackies for the first stretch here. We've got small, weak swell and winds that just won't cooperate. The water is warm, coming in at 71°F, which is a good few degrees above normal, but that's about the only highlight.
Thursday the 10th is a washout. There's a 3ft SW groundswell with a 17-second period, but that SSE cross-onshore breeze just chops it all up. The wave energy is moderate at 476, but it's all for nothing. Friday and Saturday aren't any better; the swell drops to 3ft and then 2ft with cross-shore winds. It's just messy.
From Sunday the 13th through Tuesday the 15th, we're looking at a proper flat spell. Swell drops to around 1ft to 2ft. It's not even worth suiting up. The numbers are down in the doldrums, energy-wise. This is a dead patch.
Things start to stir again on Wednesday the 16th. Swell bumps back up to 3ft from the SSW with an 18-second period, and energy climbs to 368. The winds are light, but still onshore. It's marginal at best. This pattern carries through the week, with the mornings looking a bit cleaner.
The first real window opens up on the weekend of the 19th and 20th. Saturday morning the 19th has a 2ft SSW swell, but the wind is a light 5 km/h cross-on breeze, almost glassy. Sunday the 20th is similar, with a 3ft SW swell, 18-second period, and a light 5 km/h offshore wind. These two mornings are your best shots for a clean, small wave. Remember, this break is inconsistent, so you'll be doing some waiting.
Into the next week, the 21st and 22nd hold around 3ft from the SW with 16-17 second periods. The mornings have light offshore winds again, which is promising. Monday the 21st looks the best, with energy at 521.
But then the swell fades again late in the week. Then, on Friday the 25th, the swell drops to 2ft, but the period jumps to a massive 21 seconds. That's very long-period groundswell. It brings a ton of energy – 439 in the morning, climbing to 475 in the afternoon. This kind of swell can be tricky at a beach and point setup like Blackies, maybe breaking a bit straight, but it has real potential for a point break. It's a long way out, so consider it promising but uncertain.
So, the first week is a write-off. The second week has a few windows, with the mornings of the 19th and 20th being the most reliable. And that last call on the 25th could be a wildcard. Keep your eyes on it.

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.
