The Lowdown
Alright crew, Rusty here. Let’s break it down. We’ve got a 16-day window, but it’s a slow start with a big gap of poor conditions before anything even looks rideable.
The first real chance is on Thursday, July 23rd, but it’s a marginal call. Blacks Beach is the spot. The swell is small, about 4 ft from the W, with a short period of 7 seconds, so it’s not holding much energy. The combined energy of all swells is weak to moderate at 203. The wind is offshore from the WSW at 10 km/h, which is a good sign, but the water is 74°, which is a massive 7° warmer than normal for this time of year — that’s very unusual. Still, it’s only a marginal forecast.
We roll through a stretch of mostly cross-onshore winds and small surf. Friday, July 24th through Sunday, July 27th stay in the marginal zone. Swells are small, 2 ft to 4 ft, mostly from the SSW or SW, with periods from 13 to 21 seconds. That 21-second groundswell on Saturday morning brings some promise, but the wind spoils it. The combined energy rises to 1091 that morning, which is solid moderate energy, but it’s wasted on a bumpy surface. The water stays very warm, but the wind is consistently cross-on or light cross-onshore.
The best of the entire window is Monday, July 27th and Tuesday, July 28th at Blacks Beach. Swell sizes hit 4 ft from the SSW, with periods of 17 to 19 seconds — that’s real groundswell. The combined energy is strong, hitting 1205 and 1269 on Monday, and 1128 on Tuesday morning. That’s a lot of power. But the wind is cross-on from the SW or SSW at 15 km/h, so it’s never clean. For an exposed spot like Blacks Beach, which is consistent and often has crowds, this is a session for locals who don’t mind a bit of chop. The 4 ft is fine for most surfers, but it’s not beginner-friendly with the wind.
After that, it fades fast. Wednesday, July 29th through Friday, August 1st drop off quickly. Swell heights shrink to 4 ft and then down to 0.3 ft by August 1st. The combined energy crashes to 15 or 20, which is nothing. There’s a big flat gap from Friday, August 1st afternoon through Sunday, August 2nd, with nearly no surf. Monday, August 3rd and beyond are a bust — short period, weak energy, messy winds.
If you’re looking for the best of it, Monday, July 27th and Tuesday, July 28th are the standouts. The swell is there, the period is long, and the energy is strong, but the wind holds it back. Don’t expect perfection. And for the rest of the run, it’s mostly a waiting game.
Rusty.

Information about the Blacks Beach Surf forecast
The above surf forecast table for Blacks Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Blacks Beach can be found by selecting the local surf guide option on the grey menu. Our Blacks Beach 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 Beach) 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 Beach 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.
