The Lowdown
Alright, folks, Rusty here. Let me level with you. I’ve been staring at the numbers for Timber-Cove, and this 16-day stretch is a tough nut to crack. The whole outlook is pretty much surf-drought material, with only one tiny window that even looks like it might work.
From now through basically all of August and into early September, the swell is weak and the winds are all over the place—cross and cross-onshore mostly. Every report says “poor surf conditions,” and the wave comments are zero after zero. There’s a bump in energy around the middle of the forecast, but the wind just chops it all up.
Here’s the only real chance. On Sunday, August 31st, the morning shows a glimmer of hope. You get a 1.7m swell from the WNW with a combined energy reading 383—that’s moderate. The wind is light and cross-onshore, so the face might hold up. But the period is super short at 7 seconds, so it’ll be lumpy. The report calls it “marginal surf forecast or questionable tide conditions,” so it’s a gamble. It’s not a standout day, it’s just the only day worth looking at.
After that, the first couple days of September have another marginal rating or two, but the wind goes onshore or fresh again, so don’t hold your breath.
This is the kind of quiet run that happens. It’s a big fat blank period. If you’re itching for a paddle, that Sunday morning (August 31st) is your only chance, and even then, keep your hopes ankle-high. Forecasts can always shift, but for now, it’s a waiting game.
Rusty.

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