Kalymnos crowds?

Hi there, Was just wondering if anyone knew how big the crowds are in certain months? I imagine there are far more climbers now in April than there will be in June? And from what I've seen so far do people typically stick to the crews they came with? Haven't really seen much cross-group socializing outside of the crags. Additionally, I'll be in Kalymnos until mid June so if anyone wanted a partner send me a message!
