For me it seems so...here in Cali it takes me more effort to run a 5:30 in chillier weather (such as now) than it does in the warmer months (August-September, when its not really hot like in June or July).
Is this the same for you guys? Colder weather = slower times in general?
Depends how cold, and the length of the race/effort. 40-50 F seems perfect for me, but I don't mind it being much warmer for a sub-5K race. Colder than mid 20s F (cold by my standards), and I would expect to be slowed down. Cold air often is dry air, which can make breathing tough for me. Also, if I have to bundle up a bit against the cold I don't do well.
Colder air is more dense, so you run slower.

It takes me 2 to 4 days to adapt to a big drop in temperature but things go back to normal after that.

Colder air has more oxygen, so as long as it is not freezing weather you can reap the benefits of the O2.
What the freezing weather does is that it solidifies the moisture so the air becomes drier.
I know I'm likely crazy, but I feel when its really cold out and I wear shorts (say below 30F), my quads don't every cooperate.
I have decided it's because the blood retreats from the surface to keep warm, thereby depriving me of full use of the muscle.

I tend to run faster in the cold. I feel like I'm running with an extra lung.
slow's me down but I can get in more miles...summer is hell
First off it was 60-70 this weekend for the majority of CA so you must live in the mountains? That's not cold.
Secondly you can look this up in Daniels book I believe. But there is an ideal temperature for distances 5k and up, somewhere around 45. The key is you are not using blood to cool the body. Also not using energy to increase temperature.
With a proper warm up, leaving sweats on until the start I think you'll find with a Bernie and gloves that 45 is a perfect temperature. You'll warm up quickly and toss them away.
But kids, it's not the density of air, it's body temperature. You aren't running as fast because you don't warm up properly. A mile run should be a 45-60 min intensive warm up. You should not be cold on the starting line.
If you run a few laps and go you got it wrong.
