This year PUEO is hosting the first annual #LāhaināNoonChallenge. For this challenge, we want you all to film and document this tropics-only phenomena as it takes place in each of your locations! Post your videos or pictures on Facebook, Instagram, and Twitter and make sure to tag us and use the hashtag #LāhaināNoonChallenge.
The goal of this challenge is to document this special day and better understand the seasonal nature of the Sun’s journey here in our island state
Lāhainā noon marks the day when the Sun becomes our zenith star, so no shadows are cast when it reaches zenith (the point directly overhead). Over the next few days/weeks: #getoutdoors and observe the shadows each day around noon and try to observe this phenomenon for yourself!
Latitude determines when youʻll experience lāhainā noon. Since the Sun is currently progressing north in its journey, the first location that will experience this event is #SouthPoint, Hawaiʻi Island on Friday, May 14th. One of the last places in the island chain to experience the first of the lāhainā noon pairs will be Lihuʻe, Kauaʻi on May 30th. Then the cycle will reverse, and Lihuʻe, Kauaʻi will experience its second lāhainā noon on July 14th, and South Point, Hawaiʻi will experience the last lāhainā Noon event in the state on July 27th.
