Strong winds can create wind chill that dramatically lowers the perceived temperature, and intense sunlight at high altitudes can lead to sunburn and dehydration. Furthermore, knowing the weather helps you decide the appropriate gear to bring, the best trails to hike, and whether to postpone your trip.

Examples & Use Cases

Case Study: A Summer Hike Gone Wrong

A group of hikers planned a summit attempt in mid-summer, assuming clear skies and warm temperatures. Despite checking the forecast, they underestimated the rapid weather changes on the mountain. As they neared the summit, a sudden thunderstorm rolled in, bringing heavy rain, hail, and high winds. The hikers, ill-prepared for such a drastic change, struggled to maintain their body temperature and visibility. They were forced to turn back, cold, wet, and shaken. This highlights the importance of thorough preparation and the need to adapt plans based on real-time weather conditions.

Use Case: Planning a Photography Trip

A photographer planned a trip to Mt. St. Helens to capture the sunrise over the crater. They meticulously researched the forecast, monitoring cloud cover and wind conditions.
