45°F is about 7°C

45°F is jacket weather with an attitude: fine in the sun, cold in the shade and colder once the wind shows up. My call is a medium-weight jacket, a puffer vest over a hoodie, or a light coat, with long sleeves underneath and closed shoes.

What I think of 45 degree weather

45°F: the weather version of a text that just says “k”.
Forty-five degrees is cold in a way that is hard to explain to anyone who is not outside.
At 45°F the wind does all the work and takes none of the blame.

What to wear running in 45 degree weather?

Runners’ rule of thumb says a run feels about 15 to 20°F warmer than the reading, so 45°F running feels like a 60 to 65°F day: shorts or tights and a long-sleeve top, with light gloves at the start.
