The Lowdown

Alright, let's have a look at what's on offer. The next couple of weeks are a bit of a mixed bag, but there's some serious firepower coming through for the experienced crew.

We're kicking off with Blackhead, a point break that's exposed to the south-east. For a beginner-friendly spot, it's inconsistent, so you gotta pick your moments. The water temp is about average for this time of year, nothing wild.

The first real window opens up on Monday the 24th. The morning starts clean with a moderate offshore wind from the WNW, pushing into a 2ft SSW swell. The energy is moderate (203), so it's not pumping, but it's a nice, clean little wave to get wet. The afternoon is where it gets interesting. That swell jumps to 8ft from the SSW with a long 13-second period, and the energy goes nuts (1695). This is excellent for experienced surfers only – 8ft is getting too big for beginners. The wind stays offshore and clean.

Tuesday the 25th is a bit of a letdown. The morning has cross-offshore wind, and the swell drops back to 4ft. The period is still long at 12 seconds, but the conditions are poor. The afternoon picks up with a fresh offshore breeze, but it's a marginal call.

Wednesday the 26th brings a return to clean conditions. Moderate offshore wind all day with a 3ft to 3ft SSW swell. The period is very long at 15-16 seconds, which means good shape and long lulls. Energy is moderate (575 and 402), making for very good surf on Wednesday morning.

Now, Thursday the 27th morning is a proper standout. You've got a 6ft SSW swell with a very long 18-second period, delivering strong energy (2277). The wind is light from the NW, making it a cross-offshore, and the conditions are clean. This is excellent for experienced surfers. The afternoon gets a bit messy with a cross-onshore breeze, so don't sleep on that morning session.

Friday the 28th morning is another good call. Clean conditions with a light cross-offshore breeze, a 5ft S swell at 13 seconds, and moderate energy (767). Very good surf.

Saturday the 29th is solid all day. Moderate offshore wind, a 3ft to 5ft S swell, and clean conditions. The afternoon has very good surf potential.

Sunday the 30th keeps the offshore wind, but the swell drops to 4ft and then 3ft. Good, clean waves, but nothing to write home about.

Monday the 31st is a write-off with marginal conditions.

Tuesday the 1st of September morning looks promising. Light cross-offshore wind, a 5ft SSW swell with a 15-second period, and very good surf potential (895 energy).

Wednesday the 2nd morning is a big one. A 8ft S swell with a 16-second period and massive energy (3372). It's marginal due to the size, but the conditions are clean. This is only for experts. The afternoon gets cross-shore and messy.

Thursday the 3rd is poor with onshore winds.

Now, hold onto your board, because Friday the 4th of September morning is absolutely monstrous. A 13ft S swell with a 20-second period – that's a very long period groundswell. The energy is astronomical (16947). The wind is light from the NNW, making it cross-offshore and clean. The catch? It's predicted to be too big for this break, so unless you're a seasoned charger looking for a beast, it's a no-go.

Saturday the 5th morning is still big at 8ft S swell, but it's clean and excellent for experts.

Sunday the 6th morning settles down to a clean 5ft S swell with very good surf.

After that, it tails off into small, ordinary conditions for the start of the second week.

So, to cut to the chase: the absolute standout sessions are Thursday the 27th morning for that 6ft clean groundswell, and then the big Friday the 4th morning if you're an expert after a challenge. For the everyday surfer, Wednesday the 26th morning and Saturday the 29th afternoon are your best bets for clean, fun waves.

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.
