The Lowdown
Alright, this is Rusty, and I’ve got the lowdown for our little corner of the surf world. Let’s get into it.
Right off the bat, things are pretty quiet. We’ve got a long, slow run of small to marginal waves through the end of July. The first standout doesn’t arrive until Monday, August 3rd, so you’re looking at about a week and a half of mostly flat or ordinary conditions before that. There’s a glimmer of hope on Tuesday morning, July 21st, but it’s tiny.
The only serious game in town is Guillotines. This is an advanced, inconsistent point break with a pretty decent exposure to the swell, but it needs the stars to align. The water is sitting at 63°F, which is about average for the time of year.
Let’s take it week by week.
Week One (July 20 – July 26):
It’s a tough stretch. Monday the 20th is a write-off – messy onshore wind and a poor surf forecast. Tuesday the 21st morning is the best of a bad lot: glassy conditions with a clean 4ft swell from the ENE and a period of 10 seconds. The combined swell energy is low-moderate at 312, but it’s a surfable wave if you’re desperate. After that, it’s a slow fade. Wednesday and Thursday are ordinary with dropping sizes (3ft down to 2ft). Friday the 24th through Sunday the 26th is a messy mix of cross-onshore winds and underpowered, short-period slop. Honestly, you can leave the boards at home.
Week Two (July 27 – August 4):
Still a lot of nothing. Monday the 27th through to Sunday, August 2nd is a grim run of tiny, weak surf with plenty of onshore chop. Swell heights mostly sit below 2ft, and the combined energy is often in the double digits – we’re talking barely a ripple (44 to 82). It’s not worth paddling out.
The Standout (August 3rd and 4th):
Finally, a pulse. Monday, August 3rd, is the clear winner. We get a solid 12ft swell from the south, with a long-period groundswell of 12 seconds. The combined swell energy is a strong 5394. This is big, powerful stuff. For an advanced crew only – if you don’t know what you’re doing, this will hurt you. The wind is light from the north, so it’s just a light cross-onshore, not ideal but workable for the crew who can handle it. Tuesday the 4th offers a bit more size to play with (7ft swells) but with a cross-shore wind, it won't be as clean. Still, it’s the only real action on the whole chart.
So, bottom line: we’ve got a solid, expert-only session arriving on August 3rd. For the rest of the forecast, it’s a waiting game.
Stay frosty.
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.
