Table - best surf conditions forecast for Guillotines over the next 16 days.
The Lowdown
Alright, Rusty here. Let’s break down the windows.
Best bet is Thursday the 13th of August, first light. Over at Guillotines (point), there’s a 7 ft south swell with 8 second period, and the wind is dead flat – glassy as a pond. Combined energy is strong at (756). This is for the advanced crowd, as it’s pushing into the big stuff. It’s an inconsistent break, so you’ll have to wait for the sets, but when they come, they’ll be clean. Water temp is around 64°, normal for the time of year.
The start of the period is slow. Monday and Tuesday are mostly chopped up. Tuesday the 11th has a 4 ft south swell with a 11 second period, but cross-shore wind makes it messy.
After that Thursday peak, it tails off fast. Friday the 14th and Saturday the 15th have tiny 2 to 2 ft swells. Saturday morning is clean with a gentle offshore from the SSW, but the energy is weak (96).
Sunday the 16th through the 18th is a flat stretch. On the 18th, you get a 6 ft SSE swell, but it’s short period (7 seconds) and only so-so.
Later in the month, the 21st has a glassy morning with small 3 ft waves, but again, weak period. The 24th and 25th have some size (5 ft to 6 ft) and fresh offshore winds, but the period stays short and conditions are marginal.
In short, the morning of Thursday the 13th is your one decent session. Everything else is chasing scraps.
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.
