The Lowdown
Alright, my fellow wave hunters, let’s break down what Inamura Point has cooking. The water’s a balmy 81°, which is running a little warm for the season – you’ll be comfy waiting for waves. But you’re gonna be waiting a while at the start. The first few days through Friday, the 18th, are a total bust. We’re talking ankle-snappers at 0.3 ft to 1 ft, with pretty much zero push. The wave energy is barely a hiccup (combined energy readings as low as 8 to 27). Don’t bother.
The show finally starts to roll in on Saturday, the 19th of September. A solid SE groundswell pushes in, hitting about 5 ft with a 13-second period. The wind is howling offshore out of the north, which is exactly what this reef needs to turn it on. Wave energy jumps into the moderate range (778 and 921 combined energy). This is your first real highlight. Sunday, the 20th, keeps that momentum with 5 ft to 6 ft waves from the SSE, still a clean 12 seconds, and still offshore. It’ll be a fun, powerful wave for the guys who know the lineup.
Monday, the 21st, things get heavy. The swell pumps up to over 8 ft from the SSE, and the combined energy rockets past 1500 – that’s a lot of water moving. The wind is a near gale offshore (31 mph), which will hold the wave faces up, but paddling out will be a mission. This is 100% experts-only territory; it’s going to be a thick, fast wall.
It dies back to near-flat conditions for the next week (0.7 ft to 2 ft), with one glassy morning on Tuesday the 22nd with zero wind, but barely any swell to ride.
Holding out hope, you get another pulse around Monday, the 28th, with waves just over 3 ft from the S with a long 12-second period. The winds stay cross-offshore, so it won’t be perfect, but it’ll be clean. The energy is moderate (over 300 combined). Tuesday, the 29th, sees the swell direction shift more to the SSW with a 14-second interval, adding a bit more push. But for Inamura, that southerly angle isn’t its best direction, so the waves might wall up a bit too straight to be epic. It’s a “maybe” session.
Bottom line: circle Saturday the 19th and Sunday the 20th on your calendar. That’s your best chance at a proper, clean head-high plus swell with the right wind. If you’re a charger with a big board, Monday the 21st is there for you. The rest is pretty lean, so don’t force it.
Catch you in the water.

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