Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data.Īll data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition, by Jean Meeus.Īll other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis. To get a sense of how much these sources agree with each other, you can view a comparison of Maple Valley and the stations that contribute to our estimates of its temperature history and climate. Stampede Pass (KSMP, 4.8%, 34 mi, east, 3,537 ft elevation change) Pierce County Airport Thun Field (KPLU, 28%, 23 mi, southwest, 118 ft elevation change) Renton Municipal Airport (KRNT, 67%, 10 mi, northwest, -394 ft elevation change).The stations contributing to this reconstruction are: The estimated value at Maple Valley is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Maple Valley and a given station. There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Maple Valley.įor each station, the records are corrected for the elevation difference between that station and Maple Valley according to the International Standard Atmosphere, and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. It connects to BDOS across the rail tracks.This report illustrates the typical weather in Maple Valley, based on a statistical analysis of historical hourly weather reports and model reconstructions from Januto December 31, 2016.

It has more elevation change on its XC trails than other areas, but there aren't very many real climbs or descents to be found. Similar to Lake Sawyer and BDOS, it's a mostly XC area with some more flowy trails. It connects to BDOS at it's main entrance, and to Lake Sawyer across the road.

It has both a freeride park with trails for every difficulty and an XC area, which also contains many high rated trails.

While easily the smallest, it offers the only real downhill and jump trails of the area, such as Gannonball, one of the largest Jump Trails in Washington. Summit Ridge is probably the most famous of the 4. It connects to Summit Ridge, via the 'Connector' trail off Route 66, connects to Henry's Ridge across the train tracks on both Route 66 and Master Link, and connects to Lake Sawyer across the road. It offers mostly more flowy XC singletrack, with some downhill trails. Black Diamond Open Space, or BDOS for short, is a project by Evergreen Mtb Alliance in conjunction with King County parks.

It connects to BDOS & Summit Ridge across a road. Lake Sawyer is an older development, and the largest of the 4, offering mostly twisty, narrow XC singletrack. Maple Valley is home to 4 underrated and expansive mostly XC riding areas.
