The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid run of swell on the cards for Lefthanders, kicking off Wednesday morning, July 22nd. This is a very consistent reef break, exposed to the swell, and it handles a westerly-southwesterly direction best. The water’s sitting at 67°, which is a touch warmer than normal for this time of year – you might not even need the thickest rubber.
The first standout is Wednesday morning, July 22nd. Yeah, it’s a big one. We’re looking at a solid 12ft swell from the southwest, with a long 15-second period pushing a massive amount of energy (5896). The wind is a light offshore breeze from the ESE, making for clean conditions. Now, this is a beginner-friendly reef, but that size is well over 8ft, so it’s expert territory only. The waves will have serious power.
Wednesday afternoon holds similar, with an 12ft SW swell at 14 seconds, energy still high (4932), and a light cross-offshore wind from the SE keeping things clean. Again, too big for the average surfer, but a dream for the experienced crew.
Thursday morning, July 23rd, drops to 8ft SW at 14 seconds, but the wind picks up to a moderate cross-offshore from the NE, so it’s still clean. Still a punchy wave for strong paddlers. Then Thursday afternoon is a real gem: the swell drops just a touch to 8ft, but the wind goes glassy, absolute zero from the NNE. The energy is still there (2125), and the conditions are perfect. This is the best window for the experienced surfer who wants clean, powerful waves.
Friday, July 24th, the swell backs off to 6ft and 5ft, still a clean SW groundswell, 12-second period, with light cross-offshore winds. The energy is dropping into the moderate range (964 and 912). This is more manageable, but still a good wave.
Saturday morning, July 25th, gets a bit messy. The swell is 6ft, but the wind swings to a moderate cross-shore from the north, creating a chop. By the afternoon, it’s a fresh cross-onshore from the NW, making it poor. Sunday, July 26th, is a write-off. Swell bumps up to 15ft and 13ft, but with a strong breeze from the SW and SSW, it’s a messy, blown-out mess. Not worth a look.
Monday, July 27th, the energy comes back in a big way. We’ve got 12ft and 10ft SW swell, long 13-14 second periods, and a clean cross-offshore breeze from the SE. The energy is very strong (3697 and 4562). Again, it’s too big for beginners, but for the experts, it’s a clean, powerful reef.
Tuesday, July 28th, is another standout. The morning is 10ft SW with a moderate cross-offshore from the NE, clean. The afternoon is the best of the day – 8ft SW, glassy conditions from the NNE, and energy still strong (3117). This is excellent, clean surf for experienced surfers.
The second week gets a bit more mixed. Wednesday, July 29th, drops to 7ft and 5ft, but with a very long period of 17 seconds. That’s a lot of energy for the size, but the wind is a fresh cross-offshore, so it’s clean. The energy is still significant (2285 and 1561). The long period will make it wall up nicely at this reef, but the sets will be spaced out. Thursday, July 30th, starts to get messy with cross-onshore winds, and by Friday, July 31st, we get a massive 16ft SW swell with a powerful 15-second period and insane energy (11258), but the wind is a strong cross-onshore, making it ugly. The first weekend of August is a complete loss with near-gale winds and huge, blown-out swell.
Then, Tuesday, August 4th, is a potential late standout. The swell is 7ft SW with a 15-second period, and the wind is glassy from the east. The conditions will be perfect, and the energy is moderate (1812). A great window for experienced surfers who can wait it out. The forecast for Wednesday, August 5th, brings another massive pulse (18ft) but with strong cross-onshore winds, so it’s not on.
Overall, the best windows are Wednesday morning, July 22nd, and Tuesday afternoon, July 28th, for the experts. The glassy Thursday afternoon, July 23rd, is also a prime pick. For the second week, the glassy Tuesday morning, August 4th, is the most promising, but it’s a long way off.
Rusty.

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