The Lowdown
Alright folks, Rusty here. Let’s have a good look at what’s cookin’ at Happys.
Right off the bat, I gotta be straight with ya: the next week or so is a tough slog. The surf is small, the winds are messy, and the energy just isn’t there. We’ve got a long dry spell from Monday the 14th right through until about Tuesday morning the 29th of September where the conditions are just poor or marginal. The wave energy is weak, staying well under 100 (65) for most of that first week, and even when it bumps up a bit mid-week, the wind is cross or cross-onshore and strong, chopping everything up.
The water temp at Happys is sitting at 69°, which is about 1° cooler than average for this time of year – nothing too unusual, just a touch on the cool side.
So, where’s the silver lining? The one true standout in this whole 16-day window comes right at the very end. On the morning of Tuesday the 29th of September, we finally see a break in the clouds. The wind shifts to a light 6 mph from the southwest, giving us a clean, cross-off breeze. The swell is a modest 4 ft from the ENE with a period of 8 seconds, and wave energy climbs into the moderate range (249). It’s not a bomb, but after all that wind, clean conditions will feel like a gift. The combined energy is moderate (249), so there's enough push for a fun session on a longboard or a mid-length. Wait, the guidance says the optimum swell direction for Happys is from the NE, and this is coming from the ENE – it’s a bit angled, but with clean wind, it’ll probably be the best we see.
Honestly, apart from that one Tuesday morning window, the rest of the outlook is pretty bleak. The middle of the second week (around the 23rd to 28th) sees some bigger swells, with heights over 5 ft and wave energy into the hundreds (170-515), but the wind is consistently onshore or cross-onshore, so it’ll be a mess. Not worth paddling out for. For those bigger, wind-affected days, this setup looks more interesting for kite surfing than paddle surfing.
To sum it up: grin and bear the flat, ugly spell. Circle Tuesday the 29th of September on your calendar. That’s your window.
Rusty.

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.
