Guillotines Surf Forecast and Surf Report

Alright, let’s get into it.

The 16-day window starts off with a bit of a waiting game. The first few days are pretty lackluster for Guillotines (Big Island). We’ve got some swell, but the wind is just all over the place, making things messy. The water temp is sitting at 64°F, which is about normal for this time of year, so a good full suit is your friend.

Monday afternoon, the 10th, is a write-off. There’s 5ft of swell but a fresh cross-shore breeze is tearing it up. Nothing to get excited about.

Tuesday the 11th, there’s a slight improvement. The morning shows a jump in energy (706) with a 5ft south swell at 11 seconds, and the wind is light and cross-offshore. It’s clean, but still not quite there. The afternoon drops off again.

The next couple of days are pretty flat and underwhelming. Wednesday the 12th just doesn’t have the size, and Thursday the 13th morning is where things start to get interesting. We see a 7ft south swell, but the period is a short 8 seconds, and the energy is moderate (817). The wind is light offshore, so it will be clean, but that short period might make it a bit walled. Still, it’s the best we’ve seen so far. That afternoon, it drops back down.

Friday the 14th is small and glassy in the morning, but nothing to write home about. The weekend is a bit of a lull, with only small waves. Sunday the 16th morning has a 4ft south swell with a moderate offshore wind, but it’s still not great.

From Monday the 17th through Wednesday the 19th, the surf is small and the winds are fickle. There’s a lot of rain showers around, but the waves are just too weak to bother with.

The following week, the 20th to the 23rd, is a real flat spell. The waves barely crack 3ft, and the energy is weak. It’s a good time to do something else.

The real standout, and honestly the only true highlight in this whole window, is Thursday the 24th. We finally see a decent pulse of south swell, pushing 6ft. The energy readings are strong (604 in the morning, jumping to 847 in the afternoon). However, the wind is light cross-onshore, which will put a bit of chop on it. The period is still short at 7-8 seconds, so it might be a bit lumpy. The 25th has a similar size but the wind is more cross-shore, so it’s not as clean.

So, looking at the whole picture, Thursday the 24th is the pick of the bunch, but don’t expect perfection. It’s got the size and the power, but the wind isn’t ideal. Everything else is either too small, too messy, or just straight-up flat. Keep an eye on that Thursday, as it’s the only real chance for a proper wave.
