Wind Average, Gust/Lull and Direction*
Each data point displays the average hourly wind speed (red) and the maximum and minimum hourly wind speed (blue shading), along with hourly averages of wind direction (purple, right axis).
Temperature, Dew Point, and Wind Chill*
This graph displays the hourly average temperature (red), instantaneous dew point at the hourly observation (yellow dot), and calculated wind chill (salmon line, right axis). Temperature is taken from an automated sensor and does not represent the summits' official temperature reading. Please refer to our official F6 for daily high, low and average temperatures. Please note that wind chill is only reported if temperature is under 50 degrees and wind speeds are above 3 mph.
Barometric Pressure History*
This graph displays hourly average pressure. The right-hand axis displays pressure in Millibars and the left-hand axis in Inches of Mercury.
