Alright, Rusty here, lookin’ at the charts for the next couple weeks. Let's get into it.

We’ve got a solid run of surf ahead, but it’s a bit of a mixed bag. The early part of the week is looking clean and fun, but things get wild and messy towards the end of the week before cleaning up again. There’s a big gap of no good surf from the 10th through the 12th, and then again on the 18th and 19th, where the swell just gets too unruly. So, you gotta pick your windows.

The standout sessions are gonna be Tuesday morning, July 7th and Thursday morning, July 9th at Blacks Reef. The water temp is about average for this time of year, nothing wild.

Tuesday morning, July 7th is a real gem. It’s glassy, with a clean 5 ft swell rolling in from the east. The combined energy is solid at 573 (moderate), and with the wind dead calm, it’s gonna be a beautiful, clean session. The period is 9 seconds, so it’s a decent, workable wave. Afternoon stays glassy with a touch more size at 6 ft, but it’s a bit cloudy.

Wednesday, July 8th is a write-off. The wind swings cross-onshore and the waves get choppy. 6 ft of east-southeast swell, but the quality is poor. Not worth paddling out.

Thursday morning, July 9th is your other magic window. Another glassy morning, this time with a 5 ft swell from the east-southeast and a combined energy of 755 (moderate). The wind is light and perfect. It’ll be clean and fun. The afternoon turns to garbage with strong cross-onshore winds and rain.

Then comes the chaos. From Friday, July 10th through Sunday, July 12th, a big southerly swell slams in. We’re talking 16 ft on Friday morning with a combined energy of 5446 (very strong), and it’s getting hammered by strong onshore winds. The setup looks more interesting for kite surfing than paddle surfing. This is a hard pass for anyone. The swell drops a bit but stays big and messy through the weekend.

Monday, July 13th is a nice reset. The swell drops to a clean 4 ft from the southeast, and the wind is glassy again in the morning. Combined energy is a lighter 467 (moderate). It’s a good, mellow session.

Tuesday, July 14th sees the swell drop further to 3 ft. The morning is clean, but it’s small. The afternoon has a better 3 ft with offshore wind, so it’s okay for a longboard.

Wednesday, July 15th is a bit of a tease. A long-period groundswell (14 seconds) from the southeast at 4 ft to 5 ft, but it’s got cross and cross-onshore winds. The long period is great for shape, but the wind will make it bumpy. It’s a marginal call.

Thursday, July 16th looks promising again. A solid 5 ft to 5 ft southeast groundswell with a 14-second period, and the morning has clean offshore winds. Combined energy is moderate (807-932). This is one to watch.

Friday, July 17th is a standout for experienced surfers only. A 10 ft south-southwest swell in the morning, clean and glassy in the afternoon. The combined energy is 2079 (strong). This is a big, powerful wave. Not for the faint of heart. The crowd factor is always a possibility here.

Saturday, July 18th and Sunday, July 19th are another no-go. The swell blows up to 18 ft with strong onshore winds. Combined energy hits 11,003 (extreme). Stay on the beach.

Monday, July 20th is a redemption day. The swell drops to 12 ft from the south-southeast, but the wind is light and cross-off. The forecast says it might be too big for the break, but for experts, the afternoon is clean and excellent. The period is 12 seconds, making it a powerful groundswell.

Tuesday, July 21st is a beauty. The swell is a clean 6 ft from the southeast with a 11-second period, combined energy 933 (moderate). The morning is glassy, the afternoon is clean. This is a perfect cap to the run.

Wednesday, July 22nd is a small, clean finish with a 4 ft southeast swell and offshore winds.

So, to sum it up: Tuesday morning, July 7th and Thursday morning, July 9th are your best bets for clean, fun waves. The big stuff on Friday, July 17th is for the brave. The rest of the time, you’re dodging wind and swell.

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.
