Why do climbers climb at night?

Climbing at night is not the norm for most climbers, as daylight provides better visibility and safety. However, there are certain situations or specific types of climbing where climbing at night may be preferred or necessary. Here are a few reasons why climbers might choose to climb at night:

Temperature and weather: In hot and arid regions, climbing during the cooler nighttime temperatures can be more comfortable and reduce the risk of heat exhaustion or dehydration. Additionally, climbing at night can help avoid storms or extreme weather conditions that may occur during the day.

Crowds and congestion: Popular climbing areas can become crowded during peak times, leading to long wait times for routes. Some climbers may opt to climb at night to avoid the crowds and enjoy a quieter experience on the wall.

Time constraints: Long multi-pitch climbs or big wall routes can take several hours or even days to complete. Climbers may start these climbs in the evening, aiming to climb through the night and finish the route by morning to stay within their time constraints.

Photography and aesthetics: Climbing at night can offer unique photographic opportunities, especially with a well-lit moon or stars in the background. Some climbers enjoy the aesthetic beauty and the different atmosphere that climbing at night provides.
