The Lowdown
Alright, Rusty here, and the local scene is looking pretty flat for a while. We've got a long stretch of nothing special in the water.
Water temp is about 55°F, pretty standard for this time of the year.
The first thing worth mentioning is Thursday the 27th morning at Guillotines. It's an advanced-only point break that's a rare one to see working. For a split second, we get a glassy 5ft swell from the S. The energy is weak (328), and the period is short at 7 seconds, so the waves will be a bit lumpy. But with that glassy surface, it's your only real window for a couple clean ones.
Friday the 28th afternoon gives you another look. The wind is light and cross-offshore, with a 3ft SSE swell and a longer 10-second period (270 energy). It's not going to be epic, but that longer period will help the waves set up better at this point. That's the pick of the week.
Then the faucet pretty much turns off. From Saturday the 29th all the way to Sunday the 7th of September, it's mostly tiny dribble with onshore wind. You'll see glassy mornings on the 29th, 30th, and 31st, but the swell drops to 1ft or 2ft. Not worth the wetsuit.
Right at the tail end, Tuesday the 8th of September morning shows a pulse of 6ft swell from the S with a short 7-second period. The energy is moderate at 443, and the wind is light and cross-shore. The period is short, so it'll be a bit crumbly. It's a long way off, so take that as a maybe.
Bottom line: the surf is poor to marginal for most of this run. Don't hold your breath.
Rusty.

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