The best time to visit Carlsbad, New Mexico, is during the spring (March to May) and autumn (September to October) months.Spring offers pleasant temperatures, typically ranging from the mid-teens to mid-twenties Celsius, and less rainfall. This makes it ideal for exploring Carlsbad Caverns National Park and enjoying outdoor activities comfortably. You'll also find the desert flora starting to bloom, adding a touch of colour to the landscape.Autumn also brings agreeable weather, with temperatures similar to spring. The summer heat has subsided, making it a good time for hiking and other outdoor pursuits. This season often provides clear skies, superb for stargazing, especially after a visit to the caverns.While summer (June to August) is popular due to school holidays, temperatures can be very high, often exceeding 35 degrees Celsius, which can make outdoor activities less comfortable during the day.
