Hawaii Weather in August

Every Island – and even districts on an island – is slightly different

LocationPrecipitation (in)Avg Temp (F)Max Temp (F)Min Temp (F)
Big Island-East11.1676.583.170.3
Big Island-West0.5281.487.575.6

30-32°C (86 – 90°F) is the average high during the days, with it usually holding steady around 31°C (88°F). Clear to partly cloudy skies are the norm 73% of the days of August. There is about a 35% chance of rain, but it’s almost always light – just like the other months we’ve covered so far. Humidity stays at 80% for highs and winds are from the same N-NE and East 77% of the time. It’s good to have tradewinds during the hot days.

If you don’t mind the heat, August is a great time to plan your vacation. Spend a lot of time in the water and you’ll be fine!
