The Lowdown

Howdy, Rusty here. Let’s get into it.

Alright, the next couple of weeks are bringing a solid run of swell to Fourth Beach, but you’ve got to choose your windows. The water’s sitting at about 62°, a touch warmer than usual for this time of year – not bad for a late winter paddle.

The big standout is Thursday, September 3. Early morning at Fourth Beach, we’ve got a 12-foot SSW groundswell with a long 15-second period. The combined energy is powerful at 5037 (moderate to strong). Wind’s a light 9 mph northerly, offshore. That’s clean, pumping surf, but it’s for the advanced crew only – beginners, stay on the sand.

Later Thursday afternoon, the swell drops to 10 feet, still from the SSW and 15 seconds. Light cross-offshore breeze keeps things tidy. Still expert territory.

Friday, September 4, is a washout. Crazy strong westerly winds near 31 mph and a big 12-15-foot swell. Messy, blown-out, dangerous.

Saturday, September 5, bounces back. A 10-foot SSW swell (14 seconds) and a 9 mph offshore northerly in the morning – clean and powerful. Again, expert zone.

From Sunday the 6th through Wednesday the 9th, it’s mostly poor. Strong onshore winds, big messy chop, and 10-foot+ swells.

Thursday, September 10, gives a nice break. Swell drops to 6 feet SSW at 15 seconds, with glassy conditions in the afternoon – just 3 mph southerly, dead calm. Energy is 1350 (moderate). Fun for a wider range of surfers.

Friday, September 11, has a clean morning: 6 feet SSW at 14 seconds with a light cross-offshore.

The next highlight is Saturday, September 12. A 7-foot SW groundswell, 13 seconds, and a fresh 16 mph offshore northerly. Clean, punchy, manageable for strong intermediates. Energy is 1714 (moderate). This is a top pick.

The following week gets more inconsistent. Thursday, September 17, has an 8-foot SSW swell with offshore N winds in the morning, then glassy afternoon – good quality. Friday, September 18, finishes with a 6-foot SSW groundswell and clean offshore winds.

Overall, the best sessions are Thursday, September 3, and Saturday, September 12. The Thursday morning has the biggest, cleanest groundswell – a true standout for experts. Saturday the 12th is your best bet for slightly smaller, still clean and powerful waves.

Crowds at Fourth Beach are “sometimes,” so expect a few others out on the good days.

Pick your moments, and stay safe.

Rusty.

Information about the Fourth Beach Surf forecast

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