The Lowdown
Alright, let’s break down what’s happening at Blacks Reef. Water temp is running around 55°F right now, which is a bit colder than normal for this time of year – grab a warmer wetsuit.
We get going on Thursday morning (30 July). Surf is around 5ft, coming from the ESE with a 12-second period – a solid groundswell that’ll have wider sets. Wind is a light cross-off from the north at 9 mph, leaving the surface glassy clean. The combined swell energy is 701 (moderate), and conditions are looking primo. This is the best of the early days: clean, fun, and head-high.
Thursday afternoon drops a little to 4ft, still clean and good. Friday morning sees the swell drop to 3ft, still clean, but by Friday afternoon it goes cross-shore and quality fades. It’s small and marginal after that.
Then things go sideways. Saturday (1 August) pumps up to 10ft in the morning and 12ft by afternoon out of the S/SSW, but the wind is howling onshore at 19 mph. Energy jumps to 1363 and 2263 (strong), but it’s blown out and lumpy. That’s a kite-surfing day, not a paddling day. Avoid it.
Sunday (2 August) drops to 8ft from the south, 12-second period, with a light cross-on breeze. Energy is still solid at 1885, but the wind keeps it messy – marginal. Monday and Tuesday have similar issues: plenty of swell (6ft to 10ft) but onshore winds and chop ruining the surface. Tuesday (4 August) has energy over 3000, but it’s straight onshore and ugly.
The mid-week is a write-off. Wednesday (5 August) has 8ft swell and onshore gales at 22 mph. Forget it.
But then – Saturday (8 August). That’s the day. Swell holds at 8ft from the SSE, 9-second period, and the wind goes glassy – dead calm on the afternoon, barely a whisper in the morning. Energy is 1218 (strong), and it’s called excellent for experienced surfers. This is the standout of the whole 16-day window. The sets will be thick and powerful on the reef. Crowds are possible, so get there early. This is for the advanced crew.
Sunday (9 August) drops to 6ft with light cross-shore winds – cleaner but weaker. Monday and Tuesday (10-11 August) are tiny, with waves barely 2-2ft and energy as low as 37. Not worth paddling out.
Late in the window, Thursday and Friday (13-14 August) see a pulse of 6-6ft easterly swell with a 10-second period, but the wind is cross-onshore and fresh at 16-22 mph. It’s choppy and lumpy. Another blank run.
So, the bottom line: Thursday morning (30 July) is a clean, fun start. But the one to really circle is Saturday (8 August) – glassy, strong, and solid. The rest is mostly onshore slop or tiny dribble. Pick your day.

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.
