The Lowdown
Alright, grab your wettie, and let’s have a proper look at what’s coming our way for Gravata.
The next week or so is a mixed bag, with some solid swell pulses but a lot of wind and size issues to work around. Water temp is sitting at 64°, which is about 1° cooler than average for this time of year, so it’s pretty standard for the season – no real shock to the system.
The best window for a proper session actually kicks off on Sunday the 6th. We’ve got a S swell pushing 8 ft to 8 ft with a period of 8 to 10 seconds, and a fresh offshore breeze from the SW. The combined energy is decent, hitting 736 on the morning and ramping up to 1110 in the afternoon. That’s a moderate to strong pulse of energy, but the period is a bit short, so the waves will be a little lumpy and lack that long-line power. It’s a solid option for the more experienced crew – 8 ft is starting to get big for beginners.
Monday the 7th drops back to 5 ft with a cleaner 10-second period from the S, but the wind swings cross-offshore and then cross-shore, so the morning might be your best bet. Nothing to write home about, but rideable.
The real standout, and I mean the one you want to circle on the calendar, is Saturday the 12th of September. The morning looks incredible – glassy conditions with the wind swinging light and offshore from the WNW, and a chunky 12 ft ESE swell. The combined energy is huge at 2818, which is strong to very strong wave energy. However – and this is a big however – this swell is predicted to be too big for this break. This is only for experts, and even then, it’s going to be a heavy, powerful beast. The afternoon drops to 10 ft with a cross-offshore breeze, still big, still only for the brave.
Sunday the 13th sees the swell drop to 7 ft, but the wind turns onshore and choppy, so that window closes fast. The next real hope is Tuesday the 15th morning, when a 6 ft SE swell lines up with a moderate offshore from the SW. The energy is moderate at 675, and the forecast says very good surf conditions. This is your second-best bet – a solid, clean wave for the intermediate and above crew.
After that, the end of the second week looks messy. We get a few clean-ish mornings with smaller surf, but the wind and swell direction don’t play nice. The 18th and 19th see a long-period SSE groundswell (15-16 seconds) hitting, but the wind is cross-onshore or onshore, ruining the shape. That long-period swell would be a dream at a point break or reef, but at a beach break like Gravata, it tends to close out and break straight.
So to wrap it up: the standout is definitely the 12th of September morning for experts only, and the 15th of September morning is the best bet for the rest of us. The rest of the time, you’re either fighting the wind or the size. Keep your eyes on the forecast, because it can always shift.

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