Since Hawaii is located closer to the equator as compared to the rest of North America, the amount of daylight time as well as the sunrise and sunset times don’t vary as much. Generally speaking the further north (or south) you go from the equator, you experience wider variation of sunrise and sunset times through the seasons. To illustrate this point, I’ll compare the longest and shortest days of the year for Honolulu, Hawaii to Chicago, Illinois.
|City||June 21 Sunrise||June 21 Sunset||June 21 Daylight Hrs||Dec 21 Sunrise||Dec 21 Sunset||Dec 21 Daylight Hrs|
|Honolulu||5:50 am||7:16 pm||13 hr 26 min||7:05 am||5:55 pm||10 hr 50 min|
|Chicago||5:16 am||8:29 pm||15 hr 13 min||7:15 am||4:23 pm||9 hr 7 min|
Notice that in Chicago, there’s more than a six hour variation of daylight hours from the longest to the shortest day of the year. For Honolulu, there’s less than a three hour difference from the longest to the shortest day of the year.
I should also mention that Hawaii doesn’t observe daylight savings time, but Chicago does. So, when trying to make apples-to-apples comparison of sunrise and sunset times, add an hour to the June times.
