The Lowdown
Alright, let’s break it down.
The first bit of action we see is Monday the 7th, but honestly, the conditions are rough from the start. The water temp is noted as being about average for this time of year. The waves will be there, but the quality is not.
Monday morning the 7th, Honokohau Harbour (Big Island) sees a 4ft SSW swell, long period of 17 seconds. That long period groundswell with a bit of a cross-on breeze will make for some straight, crumbly lines across this reef set-up. It’s a consistent spot but the energy is moderate to strong (1282), yet the wave comment calls it marginal, so don’t get your hopes up. The afternoon pushes up to 5ft SW, period drops to 13 seconds, still cross-on. Not a standout.
Tuesday the 8th is a write-off for quality-- 8ft SW swell in the morning with 11 second period, fresh cross-shore wind turning the surface into lumpy cross-chop. That’s a lot of water (1768 combined energy) but it’s messy. Too big for beginners and no fun for anyone else with that wind. Afternoon drops to 6ft but the wind is still cross-shore.
Wednesday the 9th, the swell fades fast. 3ft SSW, 14 seconds in the morning, gentle cross-on, and the score is a flat zero. The energy drops to 459, weak. Afternoon has a brief window with onshore wind and 3ft SSW, but still marginal.
From Thursday the 10th all the way through to Tuesday the 22nd, we get a long stretch of tiny surf. Most days are 1ft to 2ft, with periods ranging from 13 to 23 seconds. That 23-second period on Monday the 14th is huge period but with only 0.7ft swell, there’s nothing to ride. The combined energy sits well under 500, often under 200, which is weak. Wind is mostly light cross-on or on, but the swell just isn’t there.
Honestly, this is a rough outlook. The only time we see any size is early on Monday and Tuesday the 7th and 8th, but the quality is trashed by wind and poor conditions. If you’re desperate, maybe Monday afternoon the 7th at 5ft SW with light cross-on is the best you’ll get-- but it’s still only a marginal call. The rest of the 16 days is flat to tiny. The consistent nature of the break keeps it from being a total dead zone, but this run looks like a real test of patience.
Hang in there, check back-- forecasts change.
