The Lowdown
Alright folks, Rusty here. Let’s have a look at what Fall Bay has cooking over the next couple of weeks.
Honestly, this stretch starts off pretty grim. The first few days are a write-off, with weak, short-period windswell and onshore or cross-shore breezes tearing things up. You're looking at a gap of no real surf until early next week, so don’t bother paddling out just yet.
Monday the 7th shows a bit of life. The Monday morning session at Fall Bay is the first thing worth getting a little keen on. We get a jump in energy with a moderate 5 ft swell from the WSW, combined with some proper period at 14 seconds – that’s a groundswell, so it’ll have some push. The wind is cross-offshore from the WNW, and the model says clean. The combined swell energy is solid (1352), a big step up from the weak 74 earlier. It’s not perfect, but it’s the first real window and the water is much warmer than normal at 66°F, a good 5°F above average for this time of year.
Wednesday morning the 9th is passable with 5 ft and clean conditions, but the period drops right off to 8 seconds, so it’ll be weaker and a bit wall-y.
Then we hit a rough patch from Thursday the 10th through Saturday the 12th. Strong winds – 19 to 25 mph – and lumpy, messy conditions with cross-onshore flow. Swell gets as big as 7 ft on Thursday, but it’s blown out. Not for paddling.
The true standout gets here on Wednesday morning, September 16th. That’s the one to circle on the calendar. Ten feet of swell from the WSW with a decent 8-second period, but the combined energy is massive (950 and 1417 on the afternoon). Plus, we’ve got light breezes from the NW, making for clean conditions. This will be a proper session, though at 10 ft it’s only for experienced surfers. It’s still over a week out, so treat that as promising but not locked in yet.
Thursday the 17th keeps some size (7 ft) with cross-shore wind, and Friday the 18th serves up another big 10 ft pulse, but the wind swings onshore and choppy, so that one’s a pass. The energy readings (1253 to 1430) are there, but the wind ruins it.
After that, it fades fast into small, weak surf from the weekend onward.
So for the best on offer: Monday morning, September 7th for the first clean, longer-period swell, and Wednesday morning, September 16th for the real punch of size and clean conditions.

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