The Köppen–Geiger climate classification made simpler (I hope so)

Well I already started

It's been a while I haven't used Qgis.
Here's a basic map for July showing the area with precipitations above 500ml.

I was going to subdivided the precipitations in 5ml categories but the highest value is 2381 ml.
Yep almost 2,4 m of rain in a single month. Almost 4 times what London receive in a year.
The maximum in January is barely over 900 ml. July is much more rainy world wide.

I'm trying to find a threshold where I can stop adding new categories. Beyond a point where increase in precipitation don't have any impact. Stopping at 300 ml still give 62 categories. That might still be too much unless I increase the resolution.
