We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

The chance that a given day will be muggy in Bonney Lake is essentially constant during January, remaining around 0% throughout.

For reference, on July 31, the muggiest day of the year, there are muggy conditions 0% of the time, while on January 1, the least muggy day of the year, there are muggy conditions 0% of the time.

Temperature and Dew Point

There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Bonney Lake.

For each station, the records are corrected for the elevation difference between that station and Bonney Lake according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

The estimated value at Bonney Lake is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Bonney Lake and a given station.

The stations contributing to this reconstruction are:

  • Pierce County Airport Thun Field (KPLU, 81%, 7 mi, southwest, -36 ft elevation change)
  • Seattle-Tacoma International Airport (KSEA, 17%, 19 mi, north, -207 ft elevation change)
  • Stampede Pass (KSMP, 2.2%, 40 mi, east, 3,383 ft elevation change)

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands.

We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
