The Lowdown
Right, listen up. Rusty here, breaking down the Cliffs forecast for the next 16 days.
The first week is a real struggle. We’ve got consistent S groundswell rolling in, with periods from 12 to 18 seconds — that’s long-period groundswell, good shape potential, but the wind is a killer. A strong breeze from the ENE at 25 to 28 mph is blowing cross-off, but it’s just too strong to make the surf any good. The water temp is about 81°, about normal for the season. The combined wave energy hits as high as 925 (moderate) on the 4th, but it’s all marked "poor surf conditions". Don’t bother with those first days.
Saturday the 5th sees a slight improvement. Wind drops to a fresh breeze from the NE at 19 mph, and the swell is 1.5m from the SSW with a 12-second period. The combined energy is 689 (moderate). It’s only "marginal surf forecast or questionable tide conditions", so maybe a longboard session if you’re patient, but nothing to write home about.
Monday the 7th is still messy, but the real standout shows up Tuesday the 8th. Swell jumps to 2.4m from the WSW, period 14 seconds, and the combined energy goes to 3023 (strong). Wind goes to ENE at 12 mph, cross-off, and the report is "marginal" — but with that size and power, this is an expert-only session. It’s going to be heavy and consistent. If you’re not experienced, stay out of the water.
After Tuesday, it drops to tiny. From Wednesday the 9th to the 13th, swell sits between 0.5m and 0.6m, with combined energies as low as 155 (weak). A few days with gentle winds on the 13th give "surfable waves but very ordinary conditions" — only good for a weak knee-high glide.
The second week’s promise comes on Tuesday the 15th afternoon and Wednesday the 16th. Swell builds back to 1.0m from the SW and SSW with a very long 18- to 21-second period. The wind is light, from the NE at 3 to 9 mph, clean offshore or glassy cross-off. The combined energy reaches 763 (moderate). Forecast says "expect very good surf conditions". That’s a beautiful, clean, long-period groundswell — perfect for the reef shelf at Cliffs. Mark that one.
Best on offer: the Tuesday the 8th for experts chasing big, powerful 2.4m WSW swell. For everyone else, the Tuesday 15th afternoon and Wednesday 16th with clean 1.0m SSW at 18 seconds and light offshore wind is the clear winner.

Information about the Cliffs Surf forecast
The above surf forecast table for Cliffs provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cliffs can be found by selecting the local surf guide option on the grey menu. Our Cliffs 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 (Cliffs) 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 Cliffs 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.
Cliffs is 8 km (5 miles) from Honolulu. If you plan a vacation in Oahu, look for hotels and other accommodation in Honolulu. Honolulu has rooms for a wide range of budgets as well as car hire and transport links.
