Summer (June - August): a fleece or light jacket, long pants, rain shell for
afternoon thunderstorms, sunglasses, sunscreen, and water. Mornings can be cool enough for a
sweatshirt even when Las Cruces is over 100°F.
Fall (September - October): add a warmer mid-layer and a hat. Aspen color
usually peaks late September into mid-October, depending on the year.
Winter (November - March): warm coat, hat, gloves, traction footwear, and
anything you would normally bring for a snow day. Tire chains are sensible if you are not in
an all-wheel-drive vehicle.
Spring (April - May): highly variable. You can get sleet, snow, sun, and wind
in a single afternoon. Layer.
