The Lowdown
Alright folks, Rusty here. Let’s get straight into it.
Honestly, the next couple of weeks at *Costa Nova* (Costa-Nova) are a tough watch for us surfers. The immediate forecast is a write-off with a lot of weak, short-period slop and onshore wind messing things up. We’re looking at a dry spell right through the weekend and into the start of the new week. There’s a real gap here with nothing rideable until Monday morning, the 27th of July.
So, let’s talk about that Monday morning, the 27th. It’s our first real chance. The wind drops out completely – glassy conditions – and we’ve got a bit of waist-high swell from the NNW, pushing about 4 ft. The energy is moderate (226), but with that glassy surface, it’ll be clean. It’s not a standout, but it’s the best we’ve seen.
Then we get another little window on Tuesday morning, the 28th. Again, we’ve got glassy conditions with a light WSW breeze. The swell is similar, 4 ft from the NNW and a period of 10 seconds, giving it a bit more shape. The energy is moderate (263). It’s a classic dawny.
After that, the winds turn onshore again and the swell drops off into the weekend. There’s a bit of a tease on Friday morning, the 31st. The swell is tiny at 2 ft from the west, but the wind is dead calm and glassy again. It’ll be a knee-high dribbler for the longboard, but not much else.
We have to wait until Thursday morning, the 6th of August, for the next real highlight. This morning looks promising. We’ve got clean, glassy conditions with a NNE breeze, and a solid 4 ft groundswell from the WNW with a 10-second period. The energy is moderate to strong (280). This could be the cleanest, most user-friendly surf in the whole run.
That morning of Thursday, the 6th, is the standout. It’s not big, but the combination of waist-high, clean groundswell and zero wind will make Costa Nova look like a different spot. Get on it early because the afternoon winds will mess it up.
Water temp is sitting at 70°F, which is much warmer than normal for the time of year by over 4 degrees – nice surprise.
Keep an eye on that Thursday morning, lads. The rest of the run is a bit of a grind, but that one session should be worth the wait.
Rusty.

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