The Lowdown

Alright, let’s break this down.

For Bonza Bay, we’re in for a rough stretch. The first real chance to get wet is Monday the 14th, and it’s a big one. We’ve got 3.0m of east swell rolling in, and the wind is light and cross-shore, which is a big plus. Energy is strong, sitting at 2051. This is solid, powerful stuff. But heads up, this is over the 2.5m mark, so it’s only for experienced surfers. The wave period is 10 seconds, which is decent, but with that size, it’s gonna be a handful.

Tuesday the 15th keeps the same swell, around 3.0m, and the wind stays light in the morning. Similar story – still too big for most, but if you’ve got the skills, it could be on. The afternoon eases a bit to 1.7m, but the wind gets a bit more cross-on, so it loses some shine.

Then the quality just drops off. From Wednesday the 17th through the 22nd, we’ve got mostly poor conditions. The wind is onshore or cross-on, and the swell is smaller, but it’s messy. There’s a slight clean-up on Wednesday the 16th afternoon, but it’s small.

Now, the standout is further down the line. Monday the 28th is the big one. We’re looking at 3.5m to 4.5m of east-southeast swell, and the energy readings are massive – 3182 and 4579. This is serious, heavy water. The wind is cross-shore, which will keep it from being too clean, but with that power, it’s going to be a heavy day. This is purely for the experts. It’s a promising forecast, but that far out, you gotta take it with a grain of salt.

There’s a small window on Saturday the 20th afternoon, with 2.3m and a light cross-shore breeze. But it’s marginal.

Otherwise, it’s a waiting game. The water is 17°, which is 3° colder than usual, so it’s a bit chilly.

No real fun for the average surfer until that big push at the end.

Rusty out.

Information about the Bonza Bay Surf forecast

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