PCT Temperature Data

The purpose of this page is to provide a snapshot of what daily temperature range you might expect along different points of the trail at the time of year when thru hikers are typically near that point on the trail. The data below, obtained from wunderground.com, show the same daily temperature trend no matter where you are on the trail.  As you might expect, the lowest temperature is observed in the early morning hours just before the sun rises and the highest temperature is observed in the early afternoon. 

Minimum temperatures at higher elevations are typically much lower due to what meterologists call the "lapse rate," or a cooling effect when air rises:  the higher your elevation, the lower the temperature.  The typical lapse rate is a reduction of temperature by 3.6 degrees Fahrenheit for every 1000 feet in elevation gain (6.5 degrees Celsius for every 1000 meters in elevation gain).  As you would expect, it is not uncommon to experience 100 degree (Fahrenheit) temperatures in the low elevation desert and temperatures far below freezing in the high elevation mountains.  Most PCT hikers carry a sleeping bag rated at 15 degrees Fahrenheit to accomodate these colder nights. 

Expect to see an extreme temperature variations as you hike the PCT.
