The Lowdown

Let’s get real. First decent surf hits Monday morning, the 14th, at Blackhead. We’ve got a solid 6ft of south swell with a 12-second period, and it’s glassy. Water’s sitting at 53°F, which is a bit colder than usual for this time of year—so grab the booties if you’re picky. This is the best of the opening stretch: clean, decent size, and the point will handle it. The energy is pumping, around 1131, so there’s real push. Afternoon, though, wind goes onshore and things get messy. Make the most of the morning.

Tuesday the 15th drops to 5ft, shorter period at 10 seconds. Morning’s clean with a slight offshore angle, but it fades by afternoon and gets chopped. Not much going on. Wednesday and Thursday are small—around 2ft—with some clean windows, but honestly, it’s flat-ish and not worth the paddle unless you’re desperate. Friday the 18th jumps back up to 8ft, but it’s short-period, 7 seconds, and the wind is howling from the south at 35 km/h (22 mph). That’s a messy, lumpy day. Not friendly.

Saturday morning, the 19th, is a different story. Swell drops to 2ft, but there’s a 15-second period and light offshore wind. Not big, but clean and lined up. Better than it looks—grab the longboard. Sunday’s a write-off with strong winds and small waves. Skip it.

Now, here’s the big one. Monday the 21st kicks off with 8ft of southwest groundswell at 19 seconds. Energy is a massive 4329. That’s a lot of water moving. The wind is offshore and clean in the morning, but it’s strong—35 km/h (22 mph) in the afternoon with a smaller 6ft. Good size, but tricky—the long period might wall it up at Blackhead. Still, it’s the biggest we’ve seen. Tuesday’s a drop-off, not worth talking about.

Wednesday the 23rd starts pushing again—12ft in the morning, but the period drops to 9 seconds. That’s a lot of short-period energy, over 2100, but it’s messy and the winds are cross. Not clean. But Thursday the 24th is the one to circle. Morning sees 12ft of southwest swell at a very long 16 seconds, with strong offshore winds. Energy is through the roof—9279. That’s a serious, powerful groundswell. Clean, offshore, and big. This is expert territory, no question—over 8ft means it’s not for the faint of heart. Blackhead will be handling it, but you need to know what you’re doing. If you’re not confident, watch from the rocks.

Friday the 25th backs off to 5ft, still south, 13 seconds, with offshore winds in the morning. Much more manageable and still decent. Saturday the 26th is smaller—around 4ft—with a mix of periods and clean winds. Fun, but nothing memorable. Sunday’s small and windy, not worth it.

The final highlight lands on Monday the 28th. Morning has 5ft of south swell, 8-second period, with offshore wind. Not huge, but clean. Then Tuesday the 29th brings it back up—6ft south at 14 seconds, with strong offshore winds in the morning. Energy is solid at 1188. Good, clean, powerful surf for the experienced crew. That’s another one to keep in mind, though it’s still over a week out, so treat it with caution.

So, if you’re picking your sessions: Monday morning the 14th is your first go-to. Then the big one on Thursday the 24th, and Tuesday the 29th as the last standout. Everything else is either too small, too windy, or just messy. Stay sharp and pick your moments.

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.
