Heat Waves And Extreme Heat Management

Heat waves can occur on many long distance trails, even at elevations that are usually cooler. Sustained high temperatures increase physical stress, change how quickly hikers use water, and can alter the character of a route when reflected heat from rock or sand is added to direct sun exposure.

Educational discussions of heat management emphasize anticipation and flexibility. Hikers may choose to hike during cooler parts of the day, such as early mornings or late evenings, and rest or take extended breaks during the hottest hours. They may also adjust clothing choices, favouring light-coloured, breathable, and sun-protective garments, along with broad-brimmed hats or sun hoodies.

Water planning becomes more conservative during heat waves. Distances between reliable sources, capacity to carry water, and the accuracy of water information on maps or in community reports all need careful review. In many regions, heat waves can coincide with increased wildfire risk and air quality concerns, adding further complexity.

Adjusting mileage goals, re-evaluating exposed sections, and allowing for additional rest days are common responses to extreme heat. In some cases, hikers may decide to skip or delay sections if conditions are beyond their personal comfort level or experience.

Heat-related illness is a medical topic, and any specific concerns about symptoms or management are often directed to health professionals. This article is limited to general planning ideas and is not medical advice.
