The Lowdown

Alright, surfers, Rusty here. Let’s cut through the noise and get straight to what matters. We’ve got a 16-day window on the cards, but it’s not going to start with a bang. The first few days are looking pretty grim, so don’t be in a hurry to wax up just yet.

The opening stretch through Wednesday the 5th and into Thursday the 6th is basically a write-off. We’re looking at tiny, weak waves with poor conditions. The energy is barely registering, with values down at 15 to 17. It’s flat, it’s messy, and the wind isn't doing us any favors. This is the kind of spell where you’re better off checking the tide pools or fixing a ding. We've got a real gap here, a few days of nothing to bother with.

Things start to look a little more promising around Friday the 15th. That’s when the ocean finally wakes up. We see a solid push of swell coming out of the south, with the energy jumping up to 560. The morning is looking the cleanest, with a light offshore wind at Guillotines (Big Island). It’s a point break that doesn’t break all that often and is inconsistent, so this is one of those times you want to be there when it does. The swell is hitting 6ft, and it’s coming from the south, which is not its absolute optimum, but it’s plenty. This is a standout for the window, make no mistake. It’s still over a week out, so don't book your flights yet, but this is the one to circle on the calendar. Saturday the 16th also has some fun surf, with clean conditions and a solid 4ft from the south.

The following week, starting Sunday the 17th, keeps the energy alive. We’ve got consistent, clean surf on offer for the start of the week. Monday the 18th looks particularly good, with a 4.5ft south-east swell and clean offshore winds. Even into Wednesday the 20th, there are fun waves on tap, with a long-period swell (12 seconds) coming from the southeast. This long period is great for a point break like this, keeping the lines lined up and giving you some proper push. The energy values for this run are all in the 300-400+ range, so there's plenty of power there.

So, to sum it up: the next week is a bust. Don’t bother. But starting next Friday the 15th, and running through the following Wednesday, we’ve got the best surf on offer. The standout is definitely the 15th and 16th, with those bigger southerly swells and clean winds. The later run is a bit smaller but more consistent and cleaner. Get your boards ready, because it’s going to get good.

Catch you in the water.

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.
