Alright folks, Rusty here. We’re looking at Blacks Reef over the next couple of weeks. This is a reef setup that’s exposed to the south, so it picks up most swells, and it’s beginner-friendly when the size is right. The water temperature is sitting at 55.6°, which is about 2.3° cooler than usual for this time of year – definitely a bit colder than average, so you’ll want a good wetsuit.
The week kicks off with some promise. Tuesday morning (July 7) we’ve got a 5.2 ft easterly swell wrapping in with a 9-second period. The combined wave energy is moderate (583), but what makes it special is the glassy conditions – light westerly wind, just 3 mph. That’ll make for clean, smooth faces. The reef handles it well, and crowds are often here, so expect company. It’s a solid choice for a morning session, especially if you’re after something mellow. By afternoon the wind shifts onshore, so the window is tight.
Wednesday and Thursday (July 8-9) see the swell pick up but the wind turns cross-onshore, making things choppy. Thursday morning pushes 6.6 ft from the south at 10 seconds, energy climbing to 1337 (moderate-strong), but the southerly breeze messes with the shape. Thursday afternoon gets ugly: 9.8 ft swell, strong cross-onshore wind at 12 mph, and energy at 2171 (strong). That’s getting into expert territory, and the conditions are poor. Friday (July 10) is a write-off – 14.8 ft swell with 25 mph cross-onshore wind and energy at 3869 (very strong). Don’t even think about it unless you’re after a beating. Saturday (July 11) drops to 8.2 ft but still onshore wind, so still messy.
The turnaround comes Sunday (July 12). The swell drops to 5.6 ft from the southeast, period 9 seconds, and the afternoon goes glassy again – 3 mph southerly wind, dead calm. Energy is moderate (786), and the wave comment says “very good surf conditions.” That’s a legit call. The reef will offer clean, peeling waves. Crowds are often, but with conditions like that, it’s worth fighting for a spot.
Monday (July 13) and Tuesday (July 14) keep the swell around 3.3-3.9 ft, with offshore or cross-offshore winds from the north. These are clean but smaller days, energy dropping to 291 and 220. Good for a longboard or a fun board, but nothing exciting.

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.
