Sal's suggestions are great!
Another trick I tried when I lived in a climate with a very long and very boring winter was to break the season up into four or six week increments and consciously wear different items depending on which "small" season I was in. So...I had "warm fall" (where fabrics could still be lightweight but colours were fall-like. "Cold fall" (where temps had fallen and I needed winter weight stuff. "Holiday" (where I brought out all my red and white and spangly stuff -- I still do this for about a month each winter!). Then there was "Late winter," which often included one or two new knits, just to get me through the boredom....and finally, "Cold spring," where I still needed warm clothes but they had to be in lighter colours to reflect the change in light.
Could you try something similar for your very long summers?
It sounds as if boredom is only part of the problem, though. I cacn easily imagine that finding business looks that work in tropical heat is extremely difficult, and maybe you're not "mindlessly scrolling" so much as hoping above hope to come up with a kind of formula that would be acceptable to you and also accessible.
What level of dressiness do the business looks need to reach? Are you at peace with the creas (i.e. linen) or not?
Brooklyn's brilliant at outfits for high summer temps, but hers are (these days) more relaxed and casual due to lifestyle changes. In the past, though, she had to dress for an office. In any case, one of her strategies is to find a silhouette that works for her and replicate it in multiple great-for-her colours, and then to accesorize with flair. So the outfit shape might stay the same, but the footwear, bracelets, bag, earrings, necklaces etc. will differ and so will the colours and the combos.
