The Lowdown
Alright, mate. Rusty here.
Look, I’m gonna be straight with you – this forecast for Sharkbay is a tough one. We’ve got a long stretch ahead with very little to get excited about. The first week is pretty much a write-off with poor conditions, and while things look a touch better later on, it’s never going to be firing. There are no two ways about it: the 16-day window starts with a gap of several days of no recommendations. The best we can hope for is a brief window of clean, small waves.
The first real glimmer of hope comes on Tuesday morning, 11th August. For a few hours, we’ve got a tiny 1ft swell rolling in from the WSW with a very long period of 16 seconds. That's a groundswell, so it’ll have some energy behind it, giving the waves shape at this reef and point setup. The wind goes glassy – flat calm. That’s the major positive. It’ll be clean, and the combined wave energy is moderate (224). It won't be big, but for a quiet, small-wave session, it's the best on offer. If you can paddle out then, go. The water temperature is about average for the time of year.
The other standout window is Thursday morning, 13th August, but with a big *if*. The swell picks up to 3ft from the WSW, with a long period of 20 seconds. The energy jumps to moderate (260). The problem is, it’s only marked as a marginal forecast due to the cross-onshore wind. It is a morning session, so you might get lucky if the wind stays light. The period is so long that a beach break might be a bit straight, but at Sharkbay’s reef and point, it could set up nicely.
After that, the surf size slowly builds towards the second week. By Friday morning, 14th August, we’re looking at 3ft swell and a bigger punch of energy (617), but again, the wind ruins it with a choppy, cross-onshore mess. Saturday morning, 15th August is the same story: 4ft swell with moderate to strong energy (553) but light cross-onshore wind making it marginal. It’s a pattern of watching the swell get better, but the wind never really cooperating for clean conditions.
For Sunday, 16th August and Monday, 17th August the mornings stay marginal with cross-shore winds and 3ft to 3ft swell. It’s not surfable in the afternoons when the wind cranks up.
The final weekend, Saturday 22nd and Sunday 23rd of August, the swell drops right back to 1ft. The long period is still there, which is nice, but it’s tiny and the wind is on it.
Honestly, if you don’t have a kite, this is a lean forecast. The Tuesday morning glass-off is your only true shot at something clean, but small. The rest is a battle with the cross-onshore wind.
Rusty.

Information about the Sharkbay Surf forecast
The above surf forecast table for Sharkbay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sharkbay can be found by selecting the local surf guide option on the grey menu. Our Sharkbay 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 (Sharkbay) 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 Sharkbay 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.
Sharkbay is 3 km (2 miles) from Playas. If you plan a holiday in Guayas, look for hotels and other accommodation in Playas. Playas has rooms for a wide range of budgets as well as car hire and transport links.
