Alright, Rusty here. Let’s have a look at the next couple of weeks at Blacks Reef.
We’re kicking off Monday, July 6th, and the early window is actually pretty decent. Monday morning you’ve got a clean 5ft easterly swell with a gentle offshore breeze from the NE – that’s gonna be glassy and fun for the early bird. The energy is moderate at 317, so nothing heavy, but it’s a solid entry point for the week.
The pattern gets a bit messy from Monday afternoon right through to the end of Sunday, July 12th. Winds turn cross-shore or onshore, and the swell jumps up. Wednesday morning July 8th sees a 7ft ESE pulse with an 11-second period and moderate wave energy (1180), but the cross-shore wind will put bumps on it. By Thursday July 9th, it gets bigger and uglier – 8ft to 13ft southerly swell by Friday with strong, fresh onshore winds and energy readings in the thousands. That’s blown-out, lumpy and only for the hardcore if they’re desperate. Honestly, from Monday afternoon through Sunday, it’s a write-off for clean surfing.
Then we get a nice reset. Monday July 13th is still a bit cross-onshore, but by Tuesday July 14th, things clean right up. Tuesday afternoon is the standout: a clean 5ft SE swell with a moderate offshore NE wind at 12 mph, and the period stretches to 12 seconds – proper groundswell energy. The combined energy is moderate at 592. That’s going to be clean, lined-up, and far more enjoyable than the chaos before it. Wednesday July 15th keeps the good trend going: 5ft SE swell, 10 to 11-second period, gentle to moderate offshore NE winds, and clean surf. Energy sits around 570 to 603. That Tuesday afternoon and Wednesday morning are the best bets in the whole outlook.
From Thursday July 16th, the swell starts to fade. You’ve got 4ft on Thursday morning, still offshore and clean, but dropping. By Friday and into the weekend, it’s small – under 3ft – and winds pick up, making it marginal at best. There’s a glimpse of something on Sunday July 19th with a 5ft southerly and a very short period of 5 to 6 seconds, but that’s gonna be weak and bumpy despite the offshore wind.
Overall, grab Tuesday afternoon July 14th or Wednesday morning July 15th. That’s your clean, lined-up window with offshore winds and a proper groundswell. The rest is either too windy, too big and messy, or too small.
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.
