Yes, sadly for all out guests---it is a miserable day weather-wise here in Paradise. It's not going to be better before tomorrow, most likely.......and that means all of you who expected sun and fun outdoors are in a bad spot. My sympathies--truly. Since Nick is a very smart dog, he suggested I post some "rainy day" ideas and some cautions as well. He's always right (Rule #1 of being owned by a GSD!), so here goes:
Maui Ocean Center will be crowded but is a good option. Next to it is a small shopping center with a few shops and restaurants in which you could while away some time, watching the waves out in Maalaea Bay.
Bailey House Museum, on the approach to I'ao Valley. Then wander down into Wailuku town, maybe eat at Cafe O Lei next to I'ao Theater, walk the 'main drag' and stop in a couple of the quirky stores there.
Queen Kaahumanu Mall--well, that kind of says it......there is a multi movie complex here, plus shops, food court, and separate restaurants. Give Fernando's or Koho's a try.
Kahului Shopping Center-not much here, but if you're up for it, explore Ah Fook's grocery. Very old and local style grocery store. On the ground level of the Lono Building (at the corner of the intersection) is Bistro Casanova. Very good food and drinks.
Maui Mall: again, the name says it....not very big, but has Whole Foods and some interesting little shops. For pet owners, there's a pet shop here......go in and check out the prices of dog food, you'll feel instant heat from the sticker shock! Dragon Dragon restaurant here is good. Also a multi screen theater here.
There's always Costco, Walmart to check too, for gifts and such.
In Puunene, try the Sugar Museum. Then head on down to Kihei and Wailea. If you don't mind getting wet, scoot over to the boardwalk by the Kealia Pond, see: …wikipedia.org/wiki/Kealia_Pond_National_Wil…
In Kihei, most of the strip malls will require some wet moments.....but there are several and plenty of shops and cafes. Try Coconuts Fish Tacos, or Stella Blues, maybe the newer places like 3's, Pita Paradise, etc.
Wailea-bring lots of $$$ and explore the shops, LOL. Tommy Bahama's here has some okay food and drink. Go explore the hotels-they will be happy to have you wander through the public spaces, shops, and restaurants.
Movie theaters down in Kihei too.
West side: Lahaina town-the smaller museums in town can be a good break. Explore Front Street but you'll get wet, not lots of shelter. Go hang out at one of the restaurants-I'd try Lahaina Pizza Company for wonderful (and dry) views over the channel. Plenty of shopping, plus movies at the Old Lahaina Center and the Wharf.
The Cannery Mall will be dry, and has a number of places. If you aren't stuffed-check out the food court. The new Mexican place is good, and Athens Greek & Ba Le are always good.
Whaler's Village-the Whaling museum and more food! Some fun "drooling" shopping here at places like Martin and MacArthur and Totally Hawaiian Gifts.
I'm not listing more places, mostly because you will all find them........and you may also opt for some card games, a good book, or naps........
Please consider the driving conditions. I separated this by area deliberately. We had a rock slide on the Pali Monday night that closed the road for about 90 minutes; there's a VERY strong probability of more slides. So, if you're in West Maui-stay in West Maui. If you're in South Maui-stay on that side.
People may not be used to driving in wet conditions, may be inattentive, and cranky-a bad mix. Last but not least, rocks and trees fall where and when they fall-the ground is very, very soft, and the winds are from the ""wrong" direction. We often have trees uproot when the combo of rain and south winds hits us.
