The Lowdown
Alright, let’s get into it. We’re looking at Rosie’s Bay here, and to be honest, it’s a bit of a slow burner for the next 16 days. The water temp is sitting pretty average for the time of year, nothing wild to report there.
The first week or so is pretty lackluster. Sunday morning (23rd August) you’ve got tiny 1 ft waves from the SSW with a 13-second period, and while the wind is glassy from the WSW, the energy is weak (128). It’s surfable but very ordinary. From Sunday afternoon all the way through to the end of the month, we’re stuck in a funk. The swell stays small, mostly 1 ft to 2 ft, and the wind is nearly always cross or cross-on, messing up what little wave there is. There’s a few days in there with marginal conditions, but nothing to get excited about. The combined energy bumps up a bit mid-week, like the 432 on the 29th, but the wind is just too messy.
Then we hit the start of September. Tuesday morning the 1st sees a pulse of 5 ft swell from the west, but it’s short period, just 9 seconds, and the wind is a cross-shore 12 mph from the SE. It’s messy and the energy (571) is moderate, but the quality is poor. Not great for paddling into.
The real standout, and the one to keep an eye on, is the afternoon of Saturday the 5th of September. Rosie’s Bay gets a 3 ft swell from the SSW, period of 17 seconds – that’s proper groundswell – and the wind goes glassy, dead calm from the NE. The energy is solid at 552. The conditions are expected to be very good. That long period stuff will wrap in nicely here, so it’s a clean, fun 3 ft on offer. Just be aware that with a long period like that, the sets will be a bit more spaced out, making the paddle out easier. This is the best bet in the whole outlook.
The following morning, Sunday the 6th, is still okay with cross-on wind, but it’s not as clean as the afternoon before.
So, if you’re thinking about a paddle, lock in that Saturday afternoon. The rest of the run is mostly marginal or poor, but that one window is the real deal.

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