It has to do with solar activity. There have been almost no sun spots recently (more sn spots = more solar activity) so we have been moving into what is called a "solar minimum". I.e. temps are going to slowly drop over the next few years.
It's actually pretty cool, the climate can be very accurately predicted by monitoring sun spots.
Guess I spoke too soon as tonight is kinda cold...had to put on socks, as my toes were getting numb, so maybe cold weather finally arrived. Of course cold weather here just means a long sleeve shirt, zip-up hoodie at worst.
