16degC sounds positively balmy to me. We got 14deg and solid rain for the past two days here.
Try to be positive and think that your fridge is not having to works so hard to keep it's contents cool.
I took this thought a step further in winter when it was -12 for weeks.

And diversified to make tequila and orange avec les icicles.

It was hard to believe I was actually putting stuff in the fridge to keep warm!
