If you’ll be active

  • Choose light colors and loose, breathable fabrics to stay cool.
  • Hydrate and seek shade at midday — heat and UV both peak in the early afternoon.

If it’s raining

Bring a light rain jacket or umbrella so you don't get soaked. The temperature is still comfortable, so a packable shell over your normal outfit is enough.

Sun protection

At 80°F the sun is usually high and strong, so dress for UV as well as heat: Wear SPF 30+ broad-spectrum sunscreen, reduce midday sun (10 a.m.–4 p.m.), and cover up. Light, loose, breathable fabrics and a wide-brim hat keep you cool while shading the skin that catches the most sun. Check today’s UV Index for your exact burn time.
