The Lowdown
Right then, let’s talk about what’s on offer at Gravata. This spot is exposed to the swell and the guide says it likes swell from the southeast, so we’ll be keeping an eye on that.
The week starts off a bit slow. Tuesday the 21st has some small waves around 4 ft from the east-northeast with an 8-second period. The morning is glassy, which is a treat, but the energy is weak (188). The afternoon cleans up with a moderate offshore breeze, making it rideable, but it’s nothing to write home about.
Wednesday the 22nd is similar. Waist-high stuff at 3 ft, east-northeast swell, period around 8 seconds. The morning has a light cross-offshore wind, so it’s clean, but the energy is still weak (179). The afternoon turns cross-on, so it gets messy. Not the best.
Now, here’s where it gets interesting. Thursday the 23rd is the standout of the early window. The swell jumps up – 6 ft in the morning from the south, building to 7 ft from the south-southeast in the afternoon. The period is 9 seconds, giving it some push. The combined energy is strong (696 in the morning, 703 in the afternoon). Morning winds are light offshore from the southwest, making for clean, peeling lines. The afternoon stays clean with a cross-offshore breeze. This is the session to aim for. The water temperature is about average for this time of year.
Friday the 24th gets blown out with onshore winds and rain. The swell is still there at 5-6 ft from the southeast, but the wind is on it, so it’s a write-off. Saturday the 25th is a bit of a mixed bag. The swell drops to 5 ft from the southeast. The morning is crossed-up, but the afternoon has a clean cross-offshore wind. The energy is moderate (344-461), but it’s not the best quality.
From Sunday the 26th through to the end of the month, the conditions take a real dip. Onshore winds dominate, the swell is small and weak, and the scores are low. There’s a brief window on Wednesday the 29th with a glassy morning and a 4 ft northeast swell, but the period is a short 6 seconds, so it’s a bit fat and weak. The energy is moderate (214), but it’s a long way from the quality of the 23rd.
Looking into the first week of August, it’s grim. Strong onshore winds from the north-northeast and northeast, blowing 15-22 mph. The swell gets bigger – 7 ft on the 1st, 6 ft on the 2nd – but with that wind, it’s just a messy, blown-out ocean. The combined energy is strong (819 on the 1st), but the conditions are poor.
Then, on the 5th of August, there’s a late highlight. Wednesday morning shows a solid 8 ft swell from the south-southeast, with an 8-second period. The combined energy is massive (1613). The wind is offshore from the southwest at 16 mph, which is strong but clean. The guide says this is excellent for experienced surfers. At 8 ft, this is expert territory. It’s a long way out, so treat it as a promising possibility, but it could be a real gem if it comes together.
All in all, Thursday the 23rd is the sure bet. The 5th of August is the one to watch for the brave.

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.
