Best time to visit Boulder, CO, USA?

  • The best time to visit Boulder is during the month of August when temperatures are still warm but accommodations are more affordable. During this time, expect to pay approximately $155/night for an accommodation for two. That's $25 less than what you would have paid in July. Average temperatures hover in the mid 70s, just a bit colder than the average 80°F you would get during peak season.
  • In Boulder, tourism peaks in the summer so expect higher lodging rates if you go around that time. The CU Graduation week (May 9th - 15th), May 24th - 30th (Memorial Day Weekend) as well as the Ironman week (June 7th - 12th) are also very popular periods, so expect the highest room rates of the year.
  • When visiting Boulder between April and June, don't forget to pack an umbrella since it rains on average 19 days each month.
