Manoa Falls weather at a glance

For the most part, Hawaii, being in the tropics, has a fairly stable range of temperatures from low 60 degrees Fahrenheit to the mid 80 degrees Fahrenheit.

Manoa Valley though, has its own microclimate and tends to be cooler and wetter due to its elevation and forests.

In fact, it’s classed as a rainforest, which means that even when it’s completely dry in nearby Waikiki, it could be raining and misty at Manoa Falls. This means that you are very likely to see a rainbow or two on the Manoa Falls Hike!
