The Lowdown
Alright folks, let’s talk Omaezaki. It’s a beach and reef setup, exposed to the south. Water temp is about 81°F, right where it should be for this time of year – nothing unusual.
We start slow, but Friday morning the 14th is when it wakes up. Swell is 4ft from the east, with a clean offshore wind (ENE at 12 mph). The combined energy is moderate at 383. Not huge, but clean and fun. That’s your morning window.
Saturday the 15th and Sunday the 16th are similar size – around 4ft to 5ft – but the wind is cross-off, making it a bit bumpy. Surfable, but not the pick.
Monday the 17th morning is the first real standout. Swell runs 5ft from the east, 10-second period, with a gentle offshore (ENE at 9 mph). Energy hits 571. Conditions look very good. Circle that one.
Tuesday and Wednesday go flat and weak. On Wednesday the 19th morning it’s glassy with a tiny 1ft from the southwest, but it’s barely a ripple.
Then we hit a dry spell. Thursday and Friday the 20th and 21st bring small, weak swell (2ft to 3ft) and onshore winds. Energy stays below 130. A flat patch.
Saturday the 22nd morning offers a pulse – 3ft from the SSW, clean offshore from the NE at 6 mph, energy 325. A small but clean wave.
But Sunday the 23rd is the beast. Morning: 6ft from the southeast, very long 17-second period, gentle offshore (ENE at 9 mph). Energy is a massive 2443 – strong. This is groundswell for experienced surfers. Afternoon goes 8ft from the SSE, same 16-second period, clean with light breeze. This is the peak. If you can handle size, this is your day.
Monday the 24th gets too big – 10ft to 12ft from the SSE. Over 8ft means experts only, and the forecast says it might be too much for this break. Tuesday and Wednesday the 25th and 26th are even bigger – hitting 13ft to 20ft. That’s heavy, serious water.
Thursday the 27th morning drops to 8ft from the SSE at 12 seconds, with clean light wind. Energy is 5443 – still huge but more manageable for experts. Afternoon swings to 12ft from the WSW with a shorter period and onshore wind, messy.
Friday the 28th drops back to 5ft from the south with a short period and onshore wind. Not worth it.
The standout sessions: Friday morning the 14th for a clean, smaller wave, and that Sunday the 23rd for the big groundswell. The week after the 17th has some promise, but that Sunday is the one to lock in.

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.
