The Lowdown

G’day, Rusty here. This forecast for Rainbow Bay is a bit of a mixed bag, but there’s one standout session that’ll get your heart pumping. The water temp is sitting at 68°, which is a touch cooler than average for this time of year, so you might want a spring suit.

Alright, let’s get into it. The first real action starts on the morning of August 16th. We’ve got a 6ft SSE swell, but it’s a short period of 7 seconds, with a moderate offshore wind from the south. The wave energy is moderate (374), but the waves are surfable, just ordinary. The wind is offshore, keeping things clean, but the short period means the waves won’t have much punch.

Come August 17th, the swell picks up a bit, hitting 6ft to 7ft from the ESE and SE, with periods of 7 to 8 seconds. The wind is cross-offshore, which is okay, but the conditions are still marginal. The energy is ramping up (509-550), but it’s not a great session.

The real highlight is the morning of Sunday, August 23rd. This is the session to circle. A 7ft SSE swell with a period of 8 seconds, and a clean offshore wind from the south. The energy is solid (676), and the conditions are good. This is a decent push of swell, not too big for a confident intermediate, but it’s got some grunt. The wind is offshore, so the waves will be clean and well-shaped. This is the best on offer.

The week following that is a bit of a letdown. Swell drops off, with a few days of poor conditions and onshore winds. The morning of August 26th is worth a mention: a 6ft SSE swell with a period of 10 seconds, and a fresh offshore wind from the south. The energy is strong (651), but the conditions are only marginal. The longer period (10 seconds) means better-shaped waves, but the wind is howling at 19 mph, which might make it tricky.

From August 28th onwards, the surf gets small and inconsistent, with heights under 3ft and weak energy. The morning of August 30th has a tiny 1ft SSE swell with a 10-second period, but it’s just not enough.

So, for the whole 16-day window, the standout is clearly the morning of August 23rd at Rainbow Bay. It’s the best call for clean, punchy waves. The rest of the period is a mix of average to poor conditions, with some gaps. It’s not a total blank, but if you’re keen, you’ll be chasing that Sunday session.

Stay frothy.
Rusty

Information about the Rainbow Bay Surf forecast

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