Climate - Elevations in the ANRA range from 8,200 to 11,000 feet. For summer, expect warm days and cool to freezing nights, especially in the high country. Many of the points of interest in the highest elevations remain inaccessible until early or mid-July. Be prepared for both warm and chilly weather. The rainy season lasts from mid-July through August, when afternoon thunderstorms should be expected. The first snow can fly any time after the first of September! Although the skies are often sunny, winter temperatures can be very cold. Abundant snowfall accumulates, which supports many winter activities found on the forests.
