The Lowdown
G’day, Rusty here. Let’s break down what’s ahead for Hiriketya Left.
Honestly, the next 16 days look grim. Plenty of swell rolling in – some of it packing serious punch – but the wind is relentless and ruining every session. There’s no day where it all comes together, so if you’re keen, you’ll be settling for the least messy option.
First surfable window is Thursday morning, August 6. Hiriketya Left has a solid 5ft SSW groundswell with a very long 17-second period, carrying strong wave energy (1940). That’s proper power and long waits between sets – perfect for a reef break – but the wind is a fresh 30 km/h westerly, cross-onshore, and lumpy. Not a morning to rush for. Afternoon drops to 6ft, still SSW, 16-second period, but a moderate cross-shore breeze keeps it chopped and marginal.
Friday August 7 is similar. Swell sits at 5ft from the south, 14-second period, energy still strong (2029 in the morning). Wind is cross-shore and fresh, so lumpy and messy. Afternoon is a repeat with moderate cross-shore chop.
Saturday August 8 morning bumps to 6ft S swell, 16-second period, energy strong (2116), but wind swings cross-onshore again, fresh and lumpy – poor. Afternoon settles to 4ft SSW, but still moderate cross-shore chop.
Sunday August 9 through Tuesday August 11 is rinse and repeat. Swell between 4ft and 6ft, periods from 14 to 19 seconds, energy strong to very strong (over 2300 on Sunday afternoon and Tuesday morning), but wind stays cross-onshore, moderate to fresh, choppy and lumpy. No go.
From Wednesday August 12 into the second week, the swell drops. Heights fall to 3ft to 5ft, periods shorten to around 11 to 16 seconds, energy drops to moderate (889 to 1278). Wind remains cross-onshore or cross-shore, so still poor to marginal. August 15 afternoon clears up – clear skies, 4ft SSE swell, 12-second period, but cross-shore wind keeps it choppy.
Around August 18 we see another pulse: 4ft to 7ft SSW swells, periods 16 to 18 seconds, energy very strong (up to 2807 on August 19 afternoon). But every session is cross-onshore, moderate to fresh breeze, and poor. Even the bigger 7ft to 7ft days on August 19 are blown out. Swell direction is perfect for this reef (SW is the optimum), but without clean wind, it’s not worth it.
Best bet? Honestly, no true standout. If you had to pick, the Saturday August 15 afternoon has clear skies and just cross-shore wind – that’s your least ugly window, with 4ft SSE swell and moderate energy (865). Still marginal. Crowds are possible here sometimes, but with conditions like this, you might have it to yourself.
Water temp is about average for the time of year, nothing unusual.
Keep an eye on that pulse around August 19-20 – serious size and power, but unless the wind changes, it’s kite country, not paddle.
Rusty.

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