For the categories, they were selected randomly. The idea was more visualization so that the user can see what type of destination each dot is.

Climate gets defined based on for example how much it is raining, how hot it is or the amount of sun. I have not fully developed this function yet, so just put it as a visualisation rather than a fact.

I think continental is something where it is a bit colder while subtropical is a bit warmer with the same amount of rain.

The website is a bit mess right now and I have not created the definitions well enough. They were put on randomly. This is something which should be fixed.

I agree with the UI, especially on Greenland where the dots are blending with the map. Sunshine Atlas is a way for me to experiment with design and functions, which I can later use on my other websites.

I think having clear and accessible definitions for these terms will really help. There are multiple ways to do that, including having a “key” block that holds the definitions, or by covering this on a FAQ page, or somesuch.

I could also see a map that can show the equivalent of thermocline lines, so that you know what areas generally fall into which categories. I think that might help people quickly zoom into an area that meets the kind of environment they’re looking for.

But overall, it looks interesting!
