Hi Daughter of Danu,
Maybe you could have a look at Jerri Totten's tarots, she has one already that is very sunny : The Distant Past tarot. Not tropical, but luxuriant and "hot weather" like. This deck is beautiful, and it gets a lot of love here on the forum. She also is working on a second tarot deck, and it seems that it will have a sun, warm, maybe tropical vibe to it too.
There are also two lenormands that you might like :
- The Jerri Totten (her again ! she is great

) "Zen Lenormand" is full of jungle plants. It has an asian jungle vibe, to me.
- The Kitch Lenormand from the White Rabbit Oracle boutique on Etsy has pink flamingos in it. I do not have this one deck, but I have two other Lenormands from her, they are stunning decks and I love the art, but I dont use them as Lenormands but as Oracles, because the images are not clear enough at first sight for a lenormand, for me. Might work for someone else, but I am peculiar when it comes to Lenormand and I dont use them if some cards might be taken for other at a glance. As oracles they are perfect. I dont know about the Kitch one, it might be different, but I do not have it so I cannot say.
If I think of something else I ll come back !
Good luck !
