The Lowdown

Alright, Rusty here, let’s talk about what’s comin’ up for Omaezaki. This is a beach and reef setup, and it’s exposed to the south swell, so it’ll pick up most of what rolls in. The water temp is sittin’ around 81°, which is pretty much normal for this time of year, so no surprises there.

We’ve got a bit of a slow start, but things pick up. Thursday morning the 13th, we’re looking at a clean 3ft wave from the SSW with a 10-second period. It’s not huge, but the offshore breeze from the ENE will keep it tidy. The combined energy is moderate at 266, so it’s surfable, but don’t expect anything too punchy. The afternoon goes a bit cross-off, so it’s alright but not a standout.

Friday the 14th, the morning cleans up again with a 3.6ft swell from the east, same 10-second period, and a solid 383 combined energy. That’s a bit more juice, and the offshore wind makes it workable. The afternoon gets a bit messy with a fresh breeze, so get it while it’s good.

Saturday the 15th has a risk of thunderstorms, and the swell pushes up to 4.6ft from the east with 558 combined energy—moderate to strong. The wind is cross-off, but the conditions are a bit marginal, so it’s not the best call if you’re picky.

Sunday the 16th through Monday the 17th, we’ve got gentle breezes, clean lines, and swell hanging around 3.6ft to 4.6ft. The energy is still moderate, and the east-southeast direction keeps it consistent. Sunday afternoon and Monday morning are good shouts, with the swell showing some life.

Now, Tuesday the 18th, the swell drops off to 2.3ft on the morning, with only 123 combined energy. That’s weak, and the conditions are just ordinary. Not much to write home about.

Wednesday the 19th, it’s a small 3ft from the SSE with a short 8-second period. The energy is low at 157, and the wind is cross-off, but it’s just not got the power for a proper session.

Here’s where it gets interesting. Thursday the 20th, we get a glassy morning with a 3.6ft swell from the south, 8-second period, and 208 combined energy. The wind is dead calm—glass-off. That’s a real treat, clean as can be. The afternoon goes cross-on, so grab the morning.

Friday the 21st, another glassy morning with 3ft from the south, 9-second period, and 177 energy. It’s small but clean. The afternoon turns cross-on, so again, early is the call.

Saturday the 22nd, risk of thunderstorms, but the morning is glassy with a 4.3ft swell from the SSW, 10-second period, and 380 combined energy. That’s a decent push, and with glassy conditions, it’s a standout window. The afternoon goes cross-off, less ideal.

Sunday the 23rd, the swell drops back to 3ft with a 9-second period, and the offshore wind from the NE keeps it clean in the morning. The energy is low at 168, so it’s a small day.

Monday the 24th, we’ve got a 4.9ft swell from the east, but it’s a short 7-second period. The morning is glassy, and the energy is moderate at 379. It’s a bit of a lumpy short-period wave, but glassy conditions make it workable.

Now, for the real standout. Tuesday the 25th, we’re looking at a 6.6ft swell from the southeast with a very long 14-second period. That’s groundswell, and it’s packing serious energy—1806 combined energy. The wind is light, near offshore in the morning, and glassy in the afternoon. This is a big, powerful swell, and it’s one for experienced surfers only. The waves will be clean, with long lines and plenty of power. For a beach and reef setup, that long period might make it a bit straight at the beach, but the reef sections should handle it.

Wednesday the 26th, the swell drops slightly to 5.6ft from the SE, still with a long 12-second period, and 1067 combined energy. The morning offshore breeze keeps it clean. Still a solid day for the more experienced.

Thursday the 27th, the swell jumps to 11.5ft from the ESE with a 14-second period, and the energy is off the charts at 4711. But here’s the thing—this is too big for Omaezaki. The forecast says it’s too big for this break, so it’s a pass for paddling. That’s more of a big-wave tow or a

Information about the Omaezaki Surf forecast

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

Omaezaki is 1 km (1 miles) from Oyama. If you plan a holiday in Shizuoka, look for hotels and other accommodation in Oyama. Oyama has rooms for a wide range of budgets as well as car hire and transport links.
