Best time to visit Hawaii?

[Aloha_Shooter]

It depends on what you want from your visit. The weather is NOT the same year-round. Hawaii has a dry season (summer) and rainy season (winter). Temperatures will still be great year-round compared to the mainland because it almost never gets below 55 (and rarely below 60) and almost never gets above 98. Humidity is usually not a problem except when they have Kona winds.

• December/January: Lot of competition with holiday travelers. Temperatures tend to be in the 70s with lows in the 60s but can go down to mid 50s. Locals will be wearing sweaters when temps go down to 60s, Coloradans probably still wearing shorts and a tee shirt. January is very pleasant even with light rains, especially after the holiday travelers are gone, but you can get some monsoon rains that will go on all day -- or even for a few days -- in this season.
• February/March: Tends to be rainy but a great time to watch the humpback whales off Maui. Hawaiian Open and Punahou Carnival occur in February but don't know if they'll still be impacted in 2022.
• April/May: Great weather, no competition with kids on Spring Break. Islands are still green from the winter rains.
• June: Great weather. Summer vacation travel heating up.
• July/August: Mango season. Need I say more? Oh yeah, peak period for mainland morons on summer vacation before school starts. IMO, there is NOTHING like a perfectly ripe mango fresh off the tree (actually picked a couple days before it gets perfectly ripe because the birds will get it if you wait). White Pirie mangos -- don't accept the Indian or Haden crap. Hadens are bigger than Piries but Piries have a better, fuller flavor. (Hadens are actually good compared to the garbage we can get in Colorado but it's like comparing 100% Kona coffee to Starbucks.) https://www.hawaii.com/discover/mango-season-festivals/
• September/October: Kids from the mainland should be back in school. Great weather. Just getting out of dry season so O`ahu is browner than winter or spring.
• November/December: Great time to get away from the weather in Colorado. Hurricane season technically doesn't end until November but really low probability of anything impacting your visit (note: low is not zero).

My usual advice is first-timers should see the typical tourist sites on O`ahu for their first time/week in Hawai`i. They have greater impact (IMO) when you haven't yet seen everything the rest of the islands have to offer and you appreciate the slower pace in Waimanalo or the Neighbor Islands more after seeing the tourist sites. I highly recommend at least 2 days if not 3 to fully appreciate Volcanoes National Park on the Big Island and a full day or more to travel around the entire Big Island. You can hit 4 different climates in that one day with the rainforest on the north end of the island, tundra in the section between Mauna Loa and Mauna Kea, desert in the south end, and even arctic if you want to go to the top of Mauna Kea.

I did just see this item: https://flipboard.com/article/one-of...Fflipboard.com . Haven't had a chance to dig into it so don't know how much of it to believe.

Oh yeah, WRT Guam. I've been to Guam. Any time is a great time to go from Guam to Hawaii.
