The Lowdown

Alright, surfers, Rusty here with a look at our local stretch of coast. We’ve got a bit of a mixed bag coming our way over the next couple of weeks, so let's break it down.

We’re starting off with a quiet spell at Broadhaven South. The water is sitting at 64°, which is a touch warmer than we normally see this time of year. For the first week or so, it’s pretty flat and messy. There’s a little pulse of energy on the Monday morning with a 3 ft W swell, but it’s weak (52) and the period’s short at 6 seconds, so not much to get excited about. The wind is offshore from the NW, which is good for clean conditions, but there’s just not enough push. Tuesday sees a bit more size, around 4 ft from the W, with moderate energy (123), but the wind picks up and the quality is just not there. Wednesday the swell gets up to 6-6 ft (energy at 268 and 362), but it’s still plagued by cross-offshore winds and short period, so expect a lumpy, disorganised mess. Thursday morning offers a brief glimmer with some 5 ft swell (219) and light offshore NNW wind, but it's rated as very ordinary. After that, it drops right off again into tiny, weak surf for days. From the 22nd to the 26th, we’re looking at swells under 2 ft with long but weak periods – honestly, not worth paddling out for.

There is a real gap of a few days with nothing rideable, but hang in there because things start to look up towards the end of the month.

The standout window kicks off on Friday, the 28th of August. The morning brings a jump in size to 7 ft from the WSW, with a proper period of 10 seconds and some serious energy pumping in at 853. The wind is light from the WSW, keeping it clean. This is the best on offer by a long shot – a groundswell with good shape, but at 7 ft, it’s pushing into expert territory and may be too much for beginners. The afternoon holds onto 7 ft (786), but the wind goes a bit cross-shore, so grab the morning session.

The next day, Saturday the 29th, the swell backs off a little to 4-5 ft (312 and 302) with a good W direction, but a fresh 19 mph offshore NW wind will have it glassy and clean. It's a solid option if the 28th is too big for you.

Then, on Sunday the 30th of August, we get another solid pulse. The morning is 7 ft from the SW (349) with clean cross-off winds, and the afternoon looks even better with 7 ft from the WSW and energy at 618. The wind stays light offshore, so expect clean, powerful lines.

The very end of the month and into September is a bit wind-affected and on the drop, so the clear winners are definitely the morning of Friday the 28th and the afternoon of Sunday the 30th. Keep your eyes on those windows.

Rusty.

Information about the Broadhaven South Surf forecast

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

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 Broadhaven South 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.
