The Lowdown

Alright folks, it’s Rusty here, and I’ve gotta be straight with you about this one. We’re looking at a pretty tough stretch ahead for Inamura Point. This place is a reef break that needs a good S swell to really work, but for the first week and a half or so, the ocean just isn’t cooperating. It’s going to be a long, frustrating wait for any kind of decent wave.

The whole first week, from Friday the 14th right through to the end of Sunday the 23rd, is pretty much a write-off. The swell is tiny, mostly around 1 ft to 2 ft, and the energy is weak, often with values under 100 (like 37 or 66). The wind is all over the place, switching between cross and onshore, creating bumpy, messy conditions. It’s just not worth paddling out for. The combined energy only starts to nudge up a bit on the 23rd, hitting 143, but with a short period windswell coming straight onshore, it’s a messy, blown-out 4 ft. That’s a hard pass.

Now, the light at the end of the tunnel. Things start to get interesting around the 24th of August. The energy jumps up, with readings of 259 and 270 on Monday, and the swell period stretches out to 14-15 seconds – that’s proper groundswell, the kind that shapes up nicely on a reef like Inamura. But the wind is still onshore, so it’s only a marginal call.

The real standout, and the only time I’d seriously recommend getting in the water, is Tuesday, the 25th of August. This is the one. The morning kicks off with a clean 3 ft swell from the SE, with a 14-second period and a moderate offshore wind (moderate energy of 258). That’s a clean, lined-up wave. Then, get this – Tuesday afternoon looks glassy. Absolutely glassy. With a light wind from the SSE, the sea will be like a mirror, and that 3 ft SE groundswell (energy of 277) will be peeling perfectly down the reef. It’s not huge, but for a surfer who knows the break, that’s a dream session. Water temp is sitting at a warm 81°F, which is pretty average for the time of year, so a spring suit or just boardshorts will do.

The next day, Wednesday the 26th, the swell builds to 4 ft and the energy jumps to 402, which is moderate energy, but the wind swings onshore, so it’s going to be a choppy, blown-out mess again. The following days into the 29th see some size but the wind is never in the right spot, making it mostly poor. So, focus your energy on that Tuesday the 25th – it’s your best and only real shot at something special.

Rusty.

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.
