What to Wear in Phoenix
Phoenix is the hottest major US city. Summer highs cross 110°F. The dry air makes the heat slightly more bearable than humid heat but no less dangerous. The right wardrobe is built around sun protection, dry-air comfort, and a different cool-season approach.
What to wear in Phoenix today
Today's answer depends on today's conditions, so the specific outfit comes from the live reading for Phoenix rather than from this page. Check what to wear right now, or read on for what stays true here whatever the date.
Three things move the answer in Phoenix more than the forecast number does: the feels-like temperature rather than the air temperature, how long you will be outside, and whether you run warm or cold. Desert (hot) conditions make that gap wider here than the daily high suggests.
Dry heat behaves differently than humid heat. Sweat evaporates instantly. You can be dehydrated without feeling sweaty. Hydrate aggressively. Sun protection is non-optional year-round.
