The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Blackhead over the next couple of weeks.
Right off the bat, Friday the 11th kicks off with a tiny 2ft swell from the south, but the cross-off wind from the WNW at 6 mph is keeping it clean. It’s a bit of a slow start, but the water is sitting at 53°F, which is a touch colder than average for this time of year – you’ll want the 4/3.
Saturday the 12th is where things start to wake up. The morning sees that swell bump up to 4ft from the SSW with a long 16-second period (groundswell), and the combined energy is sitting at a moderate 725. Conditions are clean, and it’s looking very good. By Saturday afternoon, the swell jumps to 7ft from the south, but the wind switches to a light cross-onshore, so it’ll be a bit bumpy.
Sunday the 13th is a big day for size but the quality takes a hit. The swell hangs around 7-7ft from the south, but the wind is swinging from cross-off to cross-shore, putting a chop on the surface. It’s marginal.
Monday the 14th is the standout of the first week. The morning is glassy – absolute perfection, dead calm from the NNW at 3 mph – and you’ve got a solid 7ft south swell with a 13-second period and strong energy (1314). This is excellent, experienced-surfer territory. The wave is going to have some push, but the glassy conditions will make it a dream. Crowds are sometimes an issue at Blackhead, so heads up.
After Monday, the swell drops and the winds get messy. Tuesday the 15th is small and choppy. Wednesday the 16th through Friday the 18th is a real lull, with waves barely hitting 2ft most of the time and weak energy (under 130). Not worth paddling out.
Saturday the 19th sees a pulse of 6-6ft SSW groundswell (16-second period) rolling in, but it’s coming with a fresh to strong offshore breeze that’ll keep it clean but make it a battle to get out. Combined energy is strong at 1630-1788, so there’s plenty of power, but you’ll be working for it.
Then another gap from Sunday the 20th through Monday the 21st – small, strong winds, not inviting.
The second standout comes on Tuesday the 22nd. Morning brings a 7ft south swell with a 15-second period and very strong energy (2093). The wind is a gentle cross-off from the NNW at 9 mph, keeping it clean. This is excellent surf for experienced surfers. The long period is perfect for a point break like Blackhead – the waves will have shape and punch.
The following days fade out. Wednesday the 23rd and Thursday the 24th drop in size and pick up lumpy wind. Friday the 25th sees a short-period 6ft swell (7 seconds) – weak, punchy, not great. The final weekend, Saturday the 26th, has some moderate 3-4ft S/SSW groundswell (long 15-17 second period) but it’s just okay.
All in all, if you want the best of it, get out Monday the 14th for glassy perfection, or Tuesday the 22nd for a powerhouse clean groundswell session.
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.
