The Lowdown
Alright, let’s get real about Blackhead. It’s an inconsistent point break that needs the right conditions to show its stuff, and it’s a good one for the beginners when it’s small. The water’s about normal for the season, so no surprises there.
The start of the window is nothing to write home about. Sunday the 9th has some weak, small waves, around 4ft, but the wind’s messy and it’s just not clean. Monday the 10th is similar. There’s a brief moment Tuesday morning the 11th with a bit more push at 4ft and a cleaner southerly swell, but still nothing special. The energy reads 643, which is moderate, but it’s not going to be a headline act.
Then we hit a rough patch. Wednesday through Friday, the wind goes onshore, the swell is coming from the wrong directions, and it’s choppy. There are a couple of days there where you just don’t want to be out there. It’s a real lull.
That changes on Saturday morning the 15th. The wind swings offshore, and we get a clean 7ft easterly swell with a 10-second period. The energy is moderate at 962. This is a nice, clean day, but the afternoon gets windier and the size steps up. It’s getting too big for the beginners by then.
Sunday the 16th is a big step up. We're looking at a solid 10ft of south swell, and with that 9-second period it’s a lot of water moving. The offshore wind is strong, so it’ll be clean, but this is serious. This isn’t a beginner wave anymore, it’s for the experienced crew. The energy is strong at 1932 to 1974.
Now for the highlight. Monday afternoon the 17th. The swell jumps to a solid 12ft from the SSW with an 11-second period, and the energy is screaming at 4740. This is a big, powerful groundswell. The forecast is for clean conditions, and this is the kind of day a point break like Blackhead was made for. If you are an expert, this is your moment. Tuesday the 18th sees the biggest numbers on the board—a massive 16ft with a 15-second period and energy of 16981—but that’s just too much. This break can’t handle that size, and with 50 km/h winds, it’s going to be a mess. Monday is the day.
The swell stays big and gnarly through Wednesday and Thursday. It’s still over 6ft with strong winds, making it difficult. By Friday the 21st, it settles down to a friendly 4ft with a clean morning window. It’s not the main event, but it’s a bit more user-friendly. The next weekend is small and inconsistent, nothing worth planning a trip around.
So, the one that stands out is Monday the 17th. That’s the big, clean, powerful swell. Saturday the 15th is a decent warm-up, but it’s not in the same league. It’s a forecast of two halves, with that monster pulse in the middle. Be ready for it.

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.
