Same thing happened last year in Portugal.
This year we had a usual wet Winter but from October 2004 (Mid Fall) then came Winter and then Spring and until June 2005 (Early Summer) there was about 2 days of rain when there's usually about 3 months of it.
In that year by mid Spring I had already fought about 6 infestations when in a regular year I don't have any worries until Early Summer.
That's climate for us.
