The Lowdown

Alright, let’s get into it.

First up, we’ve only got one spot to look at this period – Cudmirrah Reef. It’s a reliable reef break that needs a south-easterly swell to really light up, and the best winds are from the north-west.

The week starts off pretty ordinary. Sunday the 9th is a write-off, just small, weak waves around 2ft to 3ft from the east with a cross-off breeze. Not worth paddling out for. The water temp is sitting at 63°, which is about average for the time of year, nothing unusual there.

Now, Monday the 10th is where things start to get interesting. Early morning, we’ve got a solid 6ft swell from the east-northeast with a period of 9 seconds and a clean offshore north-northwest wind at 15 mph. This is a standout session. The reef will be handling that size well, offering some proper waves. The combined swell energy is a solid 585 (moderate to strong). The wind stays offshore through the afternoon too, though the swell drops to 6ft and the direction shifts a bit, so the morning is the pick.

Tuesday the 11th is a mixed bag. The morning is small and messy with a cross-off wind, not worth it. But Tuesday afternoon brings a nice little pulse from the south at 4ft, with a 12-second period (that’s a groundswell) and clean offshore west-northwest wind. For a reef setup like this, that longer period will mean good shape and energy, but watch for longer lulls between sets. Combined energy is 442 (moderate).

Wednesday the 12th has a clean, offshore morning with 3ft swell from the south. Nice and tidy, good for a relaxed session. The afternoon turns cross-off and the waves drop, so get it early.

Thursday the 13th gets a bit tricky. Morning has a 5ft south swell but a cross-shore wind, so it’ll be a bit bumpy. The afternoon sees the swell jump to 7ft from the south with a 10-second period, but the wind turns onshore. That’s a lot of water and a lot of push, but the onshore will make it messy. Only for experienced surfers if you’re keen.

Friday the 14th morning is a beauty – glassy conditions with 4ft of south swell. Dead calm, zero wind. That’s a clean, fun session right there. Get on it. The afternoon gets a light onshore, so the morning is the clear winner.

From Saturday the 15th through to Monday the 17th, it’s a bit of a lull. Swells are small, wind is onshore or cross-on, and the waves are poor quality. Not much to get excited about.

Tuesday the 18th and Wednesday the 19th see some improvement. Wednesday morning the 19th has 5ft from the east with glassy conditions – that’s a hidden gem. Combined energy is 227 (moderate). Light rain showers but the wind is dead calm. Clean waves.

Thursday the 20th morning is another glassy session, 5ft from the east-northeast. That’s a solid, clean option. The afternoon sees the swell build to 6ft but the onshore wind kicks in, so stick to the morning.

Friday the 21st and Saturday the 22nd both have consistent 5ft east-northeast swells with cross-off winds, making for clean, fun waves. Saturday morning especially has a combined energy of 604 (moderate to strong) and the wind is light and cross-off. That’s a real standout for the second week.

Sunday the 23rd turns ugly. Strong onshore winds from the southeast at 22 mph, rising to 28 mph in the afternoon with rain. The reef will be a washing machine. Stay out.

Monday the 24th is still poor, with onshore winds and messy conditions. The swell is there at 4-5ft but the wind ruins it.

So, looking at the whole picture, the absolute best sessions are Monday morning the 10th – that’s the big one with 6ft, offshore wind, and plenty of power – and Friday morning the 14th for the glassy, clean conditions. Saturday the 22nd morning is also a top pick for the second week if you’re planning ahead. For beginners, stick to the smaller days like Wednesday the 12th morning or Friday the 14th morning, as the bigger swells (over 5ft) will be too much.

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 Cudmirrah Reef 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.
