The Lowdown

Alright, let’s get into it. We've got some solid surf on the docket, but it's a mixed bag of quality and size. There’s a good window of groundswell from the southwest coming, but the wind is going to be the deciding factor between epic and ordinary. There’s a real standout couple of days here, but also some wild, blown-out stuff that’s only for the hardcore.

We start things off proper on Wednesday the 19th. Long Beach (Western Australia) has the first real push of swell, a clean 8ft of southwest groundswell with a 12-second period. The wind is a gentle offshore breeze, so it’s glassy and clean. The energy is strong, and it’s holding through the afternoon. This is a great way to kick things off. It's a bit of size for the average punter, but the conditions will make it look better than it is.

Thursday the 20th sees the swell jump up to a punchy 12ft on the morning session. The period stretches to 13 seconds, and the offshore wind is light. It’s going to be a serious, powerful day. This is one for the experienced crew, no doubt. The afternoon, the wind swings more southeasterly and picks up, making things a bit messier.

Friday the 21st is a drop in size, down to around 5ft, and the wind is cross-off. It’s still clean, but the energy drops a lot and the quality is just not there. Saturday the 22nd starts poor with onshore winds, before a little bump of 8ft later in the day, but it won't be pretty.

Now, here’s the real standout. Sunday the 23rd. The swell comes back up to a solid 10ft from the west-southwest, with a long 13-second period. The wind is light offshore in the morning, and it’s just clean. This is the pick of the first week. It's powerful, lined-up, and the break will be holding. The afternoon settles into a very good 7ft. A proper day.

Monday the 24th is a bit smaller, but the wind’s good, and it stays clean. A good, fun wave in the 5ft to 5ft range. Tuesday the 25th is compromised by a fresh, cross-off breeze, even though the swell is solid at 8ft and the period is a long 14 seconds. It’s going to be bumpy, hard work.

Wednesday the 26th, the wind drops to nothing. It’s glassy. A clean 6ft of west-southwest groundswell. This is a good, user-friendly day.

Thursday the 27th turns poor again with onshore winds. Friday the 28th looks like another good one. The swell is back up to 8ft, the period is 12 seconds, and the wind is offshore. It should be clean and powerful all day.

The weekend brings a big change. Saturday the 29th is when things get serious. The swell is building, and it's big. Morning is a solid 12ft, and by the afternoon it’s a huge 15ft. The wind is howling, but it’s offshore early, so it will be big and serious. This is big-wave territory.

Sunday the 30th gets even more wild. A near-gale-force wind will be howling, making conditions terrible despite the 10ft swell. Not a paddle. Monday the 31st brings the wind back around, but it's still too strong, and the surf is down. The end of the month is a mess.

Looking into the first week of September, things get chaotic. The 1st and 2nd are blown out with onshore winds, it’s just no good. Then, on Thursday the 3rd of September, the bottom drops out of the charts. A massive 20ft swell with a 14-second period is forecast, but the winds are cross-onshore, so it’s going to be a total mess. That’s a week away, so it’s one to keep an eye on, but the potential is huge.

So, if you’re picking your days, Sunday the 23rd is the clear winner, and Friday the 28th is the other standout. The rest is a case of picking through the scraps.

Information about the Long Beach Surf forecast

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