Wyoming weather is highly variable and can be extreme. Warm days and cool nights are the norm in the summer. There is little shade on hiking trails so make sure to bring extra water, hats, and sunscreen. However, even when it's in the 80s in the daytime, it can cool down into the 30s at night. Light frosts are common on summer nights and it can snow even in July. Thunder and lightning storms commonly roll through on summer mornings or evenings. If visiting in the spring, fall, or winter, come prepared for snow and varying winter conditions.
