Alright, let’s put it in feet and miles per hour.
Same story: first few days are flat. Nothing happening.
Then Friday July 11 starts to show life, but it’s still small—around 1 ft from the west, period 14 seconds. Clean but ordinary. The Saturday afternoon brings a bump to about 2 ft from the southwest with an 18-second period. That’s a long-period groundswell starting to roll in.
Monday July 13 afternoon is where it gets good. Swell hits about 3 ft from the west, 17-second period. Combined energy is strong (533). Winds are a light cross-off breeze around 9 mph. Clean, lined-up waves at Polihale (Kauai).
Tuesday July 14 morning is the best: 3 ft west swell, 16-second period, combined energy at 609—very strong. Wind is almost glassy, just a slight air from the ENE at 3 mph. That’s as good as it gets.
Wednesday July 16 morning is also excellent: 4 ft west swell, 16 seconds, energy at 692. Still clean with cross-off winds.
After Thursday July 17, the swell drops. Friday morning is still tidy: 2 ft west swell, 14 seconds, and glassy calm winds. Then it fades into small, ordinary surf through the 20th.
The sweet spot is Monday July 13 afternoon through Thursday July 16 morning. Long-period groundswell, clean winds, solid energy. Polihale is the call.

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