Sun safety in Toronto

Toronto sits at latitude 43°N, so summer UV climbs quickly around the solstice. UV can reach very high levels between May and August, often peaking near solar noon. Health Canada recommends sun protection whenever the UV index is 3 or above, which Toronto regularly exceeds for several hours on clear summer days.

UV categories

  • Low (up to 2): Sun protection not usually needed.
  • Moderate (up to 5): Wear sunscreen, a hat and sunglasses.
  • High (up to 7): Reduce time in the sun 10am-4pm. SPF 50+.
  • Very high (up to 10): Avoid the midday sun. Full sun protection.
  • Extreme (11+): Stay indoors during peak UV hours.
