The Lowdown
Righto, let’s get into it.
The coming fortnight is a bit of a mixed bag. We’ll see some small windows of decent surf, but there’s a lot of wind and junk to sift through, so you’ll need to pick your moments.
Cudmirrah Reef is the only break on offer here, so all eyes are on it. It’s a reef setup, very consistent, and only for advanced crew. Water temp is sitting at 64°, which is about a degree and a half warmer than usual for this time of year—nothing wild, but you’ll notice it’s a touch more comfortable.
We kick off on Sunday the 13th with small, clean surf. Morning brings a 3ft S swell at 10 seconds, with a light N breeze keeping things cross-off and tidy. The wave energy is moderate (164). It’s not going to blow your mind, but it’s surfable and clean. The afternoon stays similar, with a bit more energy (223), and conditions still looking good.
Monday the 14th starts smaller at 2ft S swell (155 energy), cross-off breeze again. The afternoon flips to a 3ft NE swell, but the period drops to a weak 6 seconds—short-period, wind-affected stuff, only moderate energy (144). It’s rideable but nothing special.
Tuesday the 15th is a write-off. Onshore winds and a building S breeze chop things up. The morning is poor, and by the afternoon, 25 km/h S winds and rain make it a total mess. Not worth paddling out.
Wednesday the 16th gets big, but it’s ugly. We’re looking at 12ft S swell, but with 35 km/h SSW cross-onshore winds, it’s lumpy, dangerous, and only for the absolute die-hard experts. Energy is very strong (1853–2060), but the wind kills any quality. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
Thursday the 17th drops a bit to 10ft S swell, but it’s still cross-onshore and choppy. The afternoon sees the wind ease and swing onshore, with a 7ft SSE swell (685 energy), but the onshore wind and marginal conditions make it a tough call. Not recommended.
Friday the 18th is a standout. Morning has a 5ft SSE swell at 8 seconds, but the real winner is the NNE breeze at just 5 km/h, keeping it cross-off and glassy. Clean, clean, clean. Moderate energy (321). This is your best bet this week. Afternoon stays small but clean.
Saturday the 19th morning is tiny—1ft S swell, but the period is a very long 17 seconds. That’s proper groundswell energy, and with a light NW offshore, it’ll be glassy. Energy is moderate (214). This is another real highlight, but the swell is small, so only for a longboard or a patient soul. The afternoon drops to 1.0ft and loses steam.
Sunday the 20th is flat. 0.7ft swell with no energy (26). Don’t bother.
Monday the 21st sees a pulse of 6ft S swell (433 energy), but it’s onshore from the SSE. Choppy and marginal.
Tuesday the 22nd has a small 3ft S swell in the morning, but the afternoon delivers a 1.0ft S swell with a ridiculous 22-second period—very long period, but tiny. Not much to work with.
Wednesday the 23rd is a write-off again. Onshore winds and rain.
Thursday the 24th brings 3ft S swell in the morning but with 30 km/h SSE onshore winds and storms. Nasty. The afternoon jumps to 6ft NE swell (401 energy), but it’s cross-onshore and choppy.
Friday the 25th stays poor. 6ft NE swell all day, but onshore winds and rain. Choppy and messy.
Saturday the 26th is a standout. Morning has a 5ft NE swell at 9 seconds, with a light NNE breeze at 5 km/h—cross-off and glassy. Clean, clean, clean. Moderate energy (376). This is the best on offer in the second week. Afternoon gets a bit more wind, but the morning session will be magic.
Sunday the 27th morning is small but clean: 3ft S swell (280 energy), light cross-off breeze. Afternoon sees a 7ft S swell with very long period (11 seconds), but light cross-shore winds keep it rideable. High energy (1057), but it’s a bit of a mixed bag.
Monday the 28th finishes off with onshore winds and lumpy 7ft S swell. Not worth it.
Overall, the clear winners are Friday the 18th morning and Saturday the 26th morning at Cudmirrah Reef. Small, clean, glassy windows with proper swell direction. If you’re free, those are your sessions.

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