The Lowdown
Yeah, look, I’m not gonna sugarcoat it. The next couple of weeks are looking pretty flat and sad around here. We’ve got a sixteen-day window, and honestly, there’s nothing on the table that’s worth getting excited about. It’s a real bummer.
We’re looking at a stretch where the swell is just tiny, the winds are mostly onshore or cross-onshore, and the energy is weak. It’s the kind of forecast that has you checking the calendar more than the surf report. There’s a good run of days with absolutely nothing, just small, choppy, blown-out lumps. We’re talking several days of this before we even get a whiff of something with a bit more push.
Harbor House (Big Island) is the only spot on the list, and it’s a breakwater, so it needs a particular kind of swell to work. It’s inconsistent at the best of times, so this kind of flat spell is pretty normal. The water temp on Monday the 10th is at 86°, which is about average for this time of year, so no surprises there.
The first real chance of anything surfable doesn’t show up until around Saturday the 15th. We’ve got a little bump of 3 ft from the SE, but it’s short-period stuff, around 5 seconds, and the wind is a cross-onshore 16 mph. It’s not going to be pretty. The combined energy is a weak 48. It’ll be lumpy and hard to paddle into.
There’s a bit more on offer around Monday the 17th and Tuesday the 18th, with the period stretching out to 8 seconds and then up to 13-15 seconds by the 18th. That longer period is a plus, as it’ll have more push, but the size is still tiny, around 1 ft. It’s the kind of swell that might offer a rare clean wave at a spot like this, but it’s not something you’d build a day around. The energy is still in the weak-to-moderate range (44).
The strongest energy we see all period is on Wednesday the 19th, with a combined energy of 66, but that’s still not saying much. The swell is a weak 1 ft from the E with an 11-second period. It’s promising, but that’s about it.
Going into the second week, things get a bit more interesting in theory, but it’s a long way out. Around the 23rd and 24th, the swell bumps up to 2-3 ft with very short, 4-second periods. That’s just wind chop, not real surf. For a breakwater setup like Harbor House, this looks more like a session for the kite surfers than for us paddle surfers.
So, in short: there are no good surf options in this entire 16-day window. It’s a blank run. But hey, that’s the nature of this place when it’s inconsistent. It doesn’t tend to stay this poor for long, and forecasts can change, so keep one eye on it for the end of the month. But for now, find something else to do with your mornings.

Information about the Harbor House Surf forecast
The above surf forecast table for Harbor House provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Harbor House can be found by selecting the local surf guide option on the grey menu. Our Harbor House 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 (Harbor House) 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 Harbor House 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.
