The figure below presents a compact representation of key lunar data for August 2021. The horizontal axis is the day, the vertical axis is the hour of the day, and the colored areas indicate when the moon is above the horizon. The vertical gray bars (new Moons) and blue bars (full Moons) indicate key Moon phases. The label associated with each bar indicates the date and time that the phase is obtained, and the companion time labels indicate the rise and set times of the Moon for the nearest time interval in which the moon is above the horizon.
Moon Rise, Set & Phases in August
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 Brewster is rapidly decreasing during August, falling from 22% to 9% over the course of the month.
For reference, on July 25, the muggiest day of the year, there are muggy conditions 22% of the time, while on January 1, the least muggy day of the year, there are muggy conditions 0% of the time.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.
The average hourly wind speed in Brewster is increasing during August, increasing from 9.6 miles per hour to 10.6 miles per hour over the course of the month.
For reference, on April 8, the windiest day of the year, the daily average wind speed is 13.5 miles per hour, while on July 26, the calmest day of the year, the daily average wind speed is 9.5 miles per hour.
Average Wind Speed in August
The hourly average wind direction in Brewster throughout August is predominantly from the south, with a peak proportion of 52% on August 22.

Definitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere).
The growing season in Brewster typically lasts for 5.3 months (160 days), from around April 30 to around October 7, rarely starting before April 11 or after May 19, and rarely ending before September 16 or after October 28.
The month of August in Brewster is reliably fully within the growing season.
Time Spent in Various Temperature Bands and the Growing Season in August
Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F.
The average accumulated growing degree days in Brewster are rapidly increasing during August, increasing by 643°F, from 1,809°F to 2,452°F, over the course of the month.

This report illustrates the typical weather in Brewster, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 5 weather stations near enough to contribute to our estimation of the temperature and dew point in Brewster.
For each station, the records are corrected for the elevation difference between that station and Brewster 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 Brewster is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Brewster and a given station.
The stations contributing to this reconstruction are: Thedford, Thomas County Airport (27%, 58 kilometers, west); Broken Bow Municipal Airport (27%, 60 kilometers, south); Ainsworth Municipal Airport (20%, 72 kilometers, north); Evelyn Sharp Field (16%, 84 kilometers, southeast); and The O'Neill Municipal Airport (10%, 114 kilometers, northeast).
All 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.
All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.
Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.
Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.

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.
