What is the best time of year to visit Roswell?

Roswell averages 281 sunny days a year, but the best months to visit are during the off season in spring (March to May) and fall (September to November) thanks to smaller crowds and cooler temps. June is the hottest month with average temps around 94°F, so be prepared with sun gear and plenty of drinking water. The average temperature throughout winter (December to February) is 55°F, and although snowfall can occur, it’s a rare experience.
