The Lowdown

Alright, Rusty here, let's take a look at what's coming down the line for Guillotines.

First up, we've got a bit of a slow start. The forecast is pretty flat for the next few days, with nothing really worth paddling out for until we get past the first few days. It's a bit of a waiting game, but hang in there.

Tuesday morning, the 21st of July, is our first real bright spot. The swell is a modest 4 ft from the ENE with a period of 10 seconds, pushing a moderate wave energy of 312. The real kicker here is the wind: absolutely glassy. That means Guillotines, a point break that is fairly exposed to the swell, is going to be looking clean as a whistle. Water temp is sitting at 63°, which is about normal for this time of year. This is the standout for the early part of the fortnight.

We get another little window on Friday morning, the 24th of July. The swell drops a touch to 4 ft from the S, with a period of 8 seconds, and the energy is moderate at 344. The wind is a light cross-offshore, keeping things clean. It's surfable, but not as good as the Tuesday glass-off.

The pattern stays pretty average through the end of July and into the start of August. The swell is small, the wind is messy, and it's just not doing the break any favours. There's a long gap here with no real recommendations.

Then, on the 4th of August, things get seriously interesting. Tuesday morning is a monster. We're looking at a 10 ft swell from the S, with a very long period of 14 seconds. The combined swell energy is a massive 5170—that's very strong. This is a proper groundswell. The wind is glassy, which is perfect. But listen, this is a significant swell over 8 ft, so this is for experts only. Beginners, stay on the beach. That long period will also mean Guillotines, being a point break, might handle it better than a beach break would, but it's still going to be a serious paddle. This is the true standout of the entire outlook, but it's a week and a half away, so keep your expectations in check.

The afternoon of the 4th of August still has a big 8 ft swell from the SSE, but the wind is a light cross-shore, and the forecast is more marginal.

So, to put it simply: if you're looking for a clean, easy session, hit Tuesday morning the 21st of July. If you're an expert with a big-wave board and a lot of patience, start circling Tuesday morning the 4th of August. Everything else in between is pretty forgettable.

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.
