could it be the weather?

At present, I go for a ride about every other day and cover between 20 and 30 miles on each ride.
We know the weather is going colder and with more winds. My problem is that my legs seem to be permanently tired, not on the ride so much, but afterwards.
Could this be due to the weather going more winterish and affecting one's level of fitness and stamina?

I've just finished googling tired legs! Had a couple of days off riding the bike to see if that was what I was needing but, if anything, felt more heavy legged this morning.
