Weather in Cairns on december ?

Hello everybody,

I plan to come back in Australia for 2 weeks in next december. However, last time i went in Cairns was in april 2001 and it was like shower… but now i saw that wet season was from november to february… so i don’t understand 😮 !

Do you thing december can allow to do snorkelling or diving anyway ? I’ll stay not more than 3 days in east cost so i don’t want to waste time under rain. 😕

Thanks in advance for your help.

Nicolas.
