March, April, October, and November are the best listed months, while June, July, and August are toughest.

Plan Tempe around extreme heat and a short comfortable window

  1. Visit in the hottest season and a winter month

    Notice cooling, shade, windows, insulation, power, water, allergies, parking, lighting, and the route from the home to care, groceries, Town Lake, parks, and arts.

  2. Price cooling and power resilience

    Review utility history, cooling, insulation, windows, shade, roof, power planning, water questions, insurance, maintenance, and the household’s plan for 171 hot days.

  3. Pair outdoor and indoor choices

    Compare Town Lake, Tempe Beach Park, Kiwanis Park, public art, arts venues, indoor culture, care, family visits, and extreme heat alternatives.

  4. Keep climate fields distinct

    Use Excellent air quality, 8.2 micrograms per cubic meter modeled fine particle pollution, Very Good allergies, High climate heat and drought, Moderate volatility, and the separate High safety hazard rows.
