Table - best surf conditions forecast for Blacks Reef over the next 16 days.
Hey there, I'm Rusty. Let's have a look at what Blacks Reef has in store for us over the next couple of weeks.
Alright mate, the outlook starts a bit rugged. We've got a solid run of surf coming through, but the opening days are a write-off for quality. From Wednesday the 8th through Saturday the 12th, it's mostly messy, with cross-onshore winds and lumpy conditions. The swell is already showing up – around 7ft on Wednesday morning, but that combined energy is moderate at 891, and it's a short-period windswell at 10 seconds. By Thursday the 9th, it gets big and ugly: a 13ft to 16ft southerly swell with a howling 28 mph cross-onshore wind, so that's a hard pass.
The first real standout window arrives on Sunday the 12th. It's still a bit of a wait, but that morning looks glassy with a light wind from the west-southwest. The swell drops to a clean 5ft from the southeast, with a period of 9 seconds. The combined wave energy is still moderate at 710, but that glassy surface is a major positive, making for a clean surf. This is a reef break, remember, so that shorter period isn't ideal, but for a beginner-friendly spot like this, the conditions will be really welcoming.
Another promising stretch opens up on Monday the 13th and into Tuesday the 14th. Clean, offshore winds from the north-northeast on Monday, with a 3ft swell from the east-southeast (350 combined energy). It's small, but clean is clean. Tuesday stays with a gentle offshore breeze and a 3ft swell.
Wednesday the 15th brings a real treat: a 4ft swell from the east-southeast, but with a very long period of 14 seconds. That's groundswell energy, and combined energy is 711. Offshore winds from the north-west in the morning keep things clean. This is one of the best on offer for the first week – cleaner, more powerful waves, but remember that long period can make it break a bit straight at a beach setup, but for a reef it'll be proper.
Now, for the second week, we're looking at a big gap. From Friday the 17th to Monday the 20th, the forecast is grim – poor surf conditions and choppy seas. Then things get really interesting. On Tuesday the 21st morning, we have a standout: glassy conditions with a 6ft south swell at a very long 14-second period. The combined energy jumps to a strong 1538. This is excellent surf for experienced surfers. The offshore wind is light, and it's glassy – the definition of a clean session. But watch out for the Tuesday afternoon, as the swell is predicted to be too big for this break at 12ft (5477 energy).
Finally, on Thursday the 23rd, we have a promising end to the outlook. Offshore wind from the north, a clean 6ft south swell with a long 14-second period, and the combined energy is strong at 1191. This is an excellent morning for experienced surfers, too.
So, the best windows are Sunday the 12th morning for a fun, glassy session, and then the standout is Tuesday the 21st morning for experienced surfers with glassy, powerful swell. Keep an eye on the second week – it looks promising but less certain. The temperature is about average for the time of year.
Rusty.

Information about the Blacks Reef Surf forecast
The above surf forecast table for Blacks Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Blacks Reef can be found by selecting the local surf guide option on the grey menu. Our Blacks Reef 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 (Blacks Reef) 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 Blacks Reef 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.
Blacks Reef is 50 km (31 miles) from the city of Gisborne. If you plan a holiday in Gisborne and Mahia, look for hotels and other accommodation in Gisborne. Gisborne has rooms for a wide range of budgets as well as car hire and transport links.
