The Lowdown
G'day, Rusty here.
Alright, let's have a look at what's on the cards for Blackhead. This is a point break that's inconsistent, so it won't be pumping every day, but when it lines up, it can be a treat. The water temp is about average for this time of year, nothing to stress about.
We've got a bit of a slow start. Wednesday the 12th and Thursday the 13th are pretty much a write-off—windy, choppy, and not worth getting wet. Friday the 14th morning is where things start to look up. We've got a 5 ft swell from the NE, but the real kicker is the glassy conditions. The wind is dead calm, which is a major positive. It'll be clean, but the swell's a bit short-period (6 seconds) so don't expect barrels.
Saturday the 15th morning is another glassy session, with a 5 ft swell from the east and a slightly longer period of 8 seconds. The combined energy is moderate (358), so it'll have a bit more push. Saturday afternoon gets messy with rain and a light cross-shore.
Then we get a serious pulse of energy. Sunday the 16th and Monday the 17th bring a big swell, but it's all wind-affected and messy. The wave energy is huge (1584 on Sunday morning), but it's a 10 ft S swell with a short period of 8 seconds and strong winds. This is expert-only territory, and the conditions are poor. Don't bother.
The standout window is all about the middle of the following week and beyond. Wednesday the 19th is the absolute highlight. We're looking at a massive 16 ft S swell with a very long period of 16 seconds. The combined energy is extreme (13109), and the wind is clean cross-offshore. This is a serious, powerful groundswell. For a point break like Blackhead, that long period will wrap in beautifully, but it's only for experienced surfers. The size alone is intimidating.
Thursday the 20th continues with an 12 ft S swell, 12-second period, and light winds, making for excellent conditions for the experienced crew. The energy is still strong (2927). Friday the 21st and Saturday the 22nd are also excellent, with 8 ft and 6 ft swells from the S and SSE, clean offshore winds, and solid energy. The 21st has a 8 ft S swell at 11 seconds with a light offshore breeze from the W—that's a classic all-day session.
If you're a beginner, the best bet is the 23rd of August. Sunday morning has a 6 ft SSE swell, 11-second period, and clean cross-offshore winds. The energy is moderate (707), and it's the only window in the second week that's manageable for less experienced surfers. After that, it fades quickly with smaller, weaker swells and some wind issues.
So, to sum it up: the first few days are a dud. The real standout is the 19th of August for the big, long-period groundswell—that's the one for the big-wave hunters. For the rest of the crew, the 21st and 22nd are your best clean, solid days.
Rusty.

Information about the Blackhead Surf forecast
The above surf forecast table for Blackhead provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Blackhead can be found by selecting the local surf guide option on the grey menu. Our Blackhead 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 (Blackhead) 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 Blackhead 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.
