The Lowdown
Alright, Rusty here, let’s talk about what’s coming up at Zenith Beach.
The next 16 days are a bit of a mixed bag. We’ve got a few windows that look promising, but also some long flat spells with nothing much to get excited about. The water temperature is sitting about average for the time of year, so you won’t need any extra rubber.
The first real standout comes on Wednesday morning, the 12th of August. Early on, we’ll see a 4 ft swell out of the south with a period of 10 seconds, and the wind is cross-off from the west-northwest at 16 mph. The energy is moderate (400), and the waves are clean. That’s a solid option for a beginner-friendly session. Later that afternoon, the wind swings more offshore out of the west at 12 mph, and the swell drops slightly to 4 ft from the south-southwest, with moderate energy (321). It’s clean and offshore, so it’s a decent pick.
Thursday morning the 13th looks poor – the swell is short period (7 seconds) and the wind is cross-off, so it’s not worth your time. After that, we’ve got a gap of a few days with no good recommendations. Friday morning the 14th has a brief window with a 4 ft south swell and offshore wind from the west-southwest at 9 mph, gentle breeze, clean conditions. The energy is low (222), but it’s a sneaky little session.
The next real highlight is on Saturday morning, the 22nd of August. That’s a week and a half out, so keep an eye on the forecast. The swell is 5 ft from the east-northeast with a long period of 11 seconds, and the wind is cross-off from the northwest at just 3 mph. The energy is strong (630), and the conditions are clean. This is the best on offer in the whole 16-day window – a proper groundswell with good shape and no wind to mess it up. The long period will make for some nice waves at this exposed beach, but it might be a bit strong for beginners.
Monday morning the 24th has a fresh offshore wind of 19 mph out of the west, with a 4 ft east-northeast swell, but energy is low (339) and the surf is marginal. Not a standout.
The last interesting bit is on Wednesday morning the 26th of August. The swell rises to 6 ft out of the south-southwest with a short period, but the wind is offshore from the west at 6 mph, and it’s clean. The energy is moderate (382). It’s a decent option if you’re keen.
But here’s the thing – the afternoon of that same day, the 26th, the swell is predicted to be 13 ft out of the south with a period of 10 seconds, and the combined energy is massive (3139). That’s way too big for this break, and it’s only for experts. The wind is onshore, so it’s messy and dangerous. Avoid that.
Overall, the best bet is Saturday morning the 22nd of August. Mark it in your calendar.

Information about the Zenith Beach Surf forecast
The above surf forecast table for Zenith Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Zenith Beach can be found by selecting the local surf guide option on the grey menu. Our Zenith 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 (Zenith 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 Zenith 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.
Zenith Beach is 12 km (7 miles) from the city of Port Stephens. If you plan a holiday in Newcastle, look for hotels and other accommodation in Port Stephens. Port Stephens has rooms for a wide range of budgets as well as car hire and transport links.
