Will I be cold?
Will I be cold in Denver in May?
Verdict
Maybe — Chilly at times.
Lows near 44°F — cool mornings and evenings, comfortable afternoons. Big diurnal swing (26°F) — layers matter more than one warm coat.
Day vs. night
Day
70°F
Comfortable
A T-shirt and a light overshirt is enough.
Night
44°F
Cold
Cold enough that a hat and gloves become mandatory.
Why
Denver in May averages highs of 70°F, lows of 44°F, 10 rainy days.
Layering wins here. A packable puffer plus a base layer handles the cool end without overheating in the middle of the day.
The day-to-night temperature swing is 26°F, which is the real story here — the average number hides how different midday and midnight feel.
