The Lowdown
G’day, Rusty here. Look, I’m gonna level with you – for the next sixteen days around Happys, it’s a tough stretch. There’s no real standout swell window, and the conditions are mostly fighting against us. The water’s sitting at 69°, which is about 2° cooler than what’s normal for this time of year, so nothing too unusual there.
We start off this Sunday the 13th with a weak, short-period ESE swell bumping around 4ft, but it’s carrying a weak energy reading (134) and that onshore SE wind at 12 mph is making a mess of it. Choppy, poor conditions – not worth paddling out for.
Monday the 14th drops to 3ft from the east, period still a short 6 seconds. Morning has a light onshore breeze, but by the afternoon the wind turns directly onshore from the east at just 6 mph, which is light, but the wave energy is low (64). Still nothing.
Tuesday the 15th morning gives a moment of hope – glassy conditions with 3ft easterly swell, but the energy is tiny (56). The wave state says “poor surf conditions,” so that glass is just on flat, bump-less water.
Wednesday the 16th afternoon sees a jump in size to 6ft from the SE with moderate energy (191), but that SE wind is howling at 22 mph. It’s fresh and lumpy – absolutely blown out.
Thursday the 17th morning has 5ft and a solid 316 energy reading from the SE, but the south wind at 16 mph keeps it cross and lumpy. Not clean.
Friday the 18th is the closest we get to something interesting. Morning has 5ft SE swell with a nice increase in period to 10 seconds and strong energy (544). But the wind is cross from the SSE at 12 mph, so it’s still messy. By the afternoon the period stretches to 12 seconds with energy hitting 749 – that’s strong groundswell potential. But the wind is cross-onshore from the ESE at 9 mph, meaning it’s fairly choppy. This break is a sheltered point that likes a NE swell direction, so this SE swell is coming in at a bad angle and the offshore wind is W, which we never get. It’s just not clicking.
Saturday the 19th morning has a trace of clean-up with a NE breeze at 3 mph and 4ft ESE swell at 12 seconds (443 energy), but the wind is still cross-onshore, and the system gives it a “marginal” call.
From Sunday the 20th all the way through the following weekend, the swell fades to nothing – under 4ft, periods dropping, and energy readings below 150 most days. The 21st morning is glassy but with only 1ft of swell – flat as a tack.
Then by Saturday the 26th, a new ENE pulse shows at 4ft with 7-second period and moderate energy (144), but the wind from the NNE at 6 mph is cross-shore. Still ordinary.
Finally, on Sunday the 27th morning, we get a glimpse of something better: 4ft from the NE, period 7 seconds, glassy conditions, with 115 energy. The wave comment says “surfable waves but very ordinary conditions.” This is the best of a bad bunch. But it’s only Sunday morning; the afternoon sees a cross-onshore breeze ruin it.
Honestly, there isn’t a single stand-out session in this 16-day window. The forecast confidence is decent for the first week, but it’s just poor surf. For a sheltered point that really needs a NE swell and W offshore wind, we’re getting the opposite. If you’re a beginner, most of this is small enough, but the wind will ruin it. For experts, there’s nothing to get excited about. Kite surfers might find the Thursday the 17th and Friday the 18th afternoons more interesting with that strong cross-onshore wind and moderate swell.
That’s the story. Hang tight – sometimes these blank runs happen, and forecasts can change. Rusty out.

Information about the Happys Surf forecast
The above surf forecast table for Happys provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Happys can be found by selecting the local surf guide option on the grey menu. Our Happys 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 (Happys) 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 Happys 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.
Happys is 2 km (1 miles) from Caloundra. If you plan a holiday in Sunshine Coast, look for hotels and other accommodation in Caloundra. Caloundra has rooms for a wide range of budgets as well as car hire and transport links.
