A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Kimberley varies throughout the year.
The wetter season lasts 5.9 months, from October 18 to April 14, with a greater than 15% chance of a given day being a wet day. The chance of a wet day peaks at 28% on February 5.
The drier season lasts 6.1 months, from April 14 to October 18. The smallest chance of a wet day is 1% on July 14.
Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 28% on February 5.
Daily Chance of Precipitation
To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day of the year. Kimberley experiences significant seasonal variation in monthly rainfall.
The rainy period of the year lasts for 7.8 months, from September 18 to May 11, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around February 12, with an average total accumulation of 2.2 inches.

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 perceived humidity level in Kimberley, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, staying within 3% of 3% throughout.

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 Kimberley experiences mild seasonal variation over the course of the year.
The windier part of the year lasts for 5.6 months, from July 19 to January 6, with average wind speeds of more than 8.3 miles per hour. The windiest day of the year is October 23, with an average hourly wind speed of 9.7 miles per hour.
The calmer time of year lasts for 6.4 months, from January 6 to July 19. The calmest day of the year is March 6, with an average hourly wind speed of 7.0 miles per hour.
Average Wind Speed
The predominant average hourly wind direction in Kimberley varies throughout the year.
The wind is most often from the west for 2.1 weeks, from September 15 to September 30 and for 2.1 months, from October 28 to December 30, with a peak percentage of 35% on December 14. The wind is most often from the north for 4.0 weeks, from September 30 to October 28 and for 8.5 months, from December 30 to September 15, with a peak percentage of 33% on October 23.
Best Time of Year to Visit
To characterize how pleasant the weather is in Kimberley throughout the year, we compute two travel scores.
The tourism score favors clear, rainless days with perceived temperatures between 65°F and 80°F. Based on this score, the best times of year to visit Kimberley for general outdoor tourist activities are from mid February to late April and from early September to late December, with a peak score in the last week of March.
The beach/pool score favors clear, rainless days with perceived temperatures between 75°F and 90°F. Based on this score, the best time of year to visit Kimberley for hot-weather activities is from early December to early March, with a peak score in the first week of January.
For each hour between 8:00 AM and 9:00 PM of each day in the analysis period (1980 to 2016), independent scores are computed for perceived temperature, cloud cover, and total precipitation. Those scores are combined into a single hourly composite score, which is then aggregated into days, averaged over all the years in the analysis period, and smoothed.
Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for fully overcast skies.
Our precipitation score, which is based on the three-hour precipitation centered on the hour in question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 0.04 inches of precipitation or more.
Our tourism temperature score is 0 for perceived temperatures below 50°F, rising linearly to 9 for 65°F, to 10 for 75°F, falling linearly to 9 for 80°F, and to 1 for 90°F or hotter.
Our beach/pool temperature score is 0 for perceived temperatures below 65°F, rising linearly to 9 for 75°F, to 10 for 82°F, falling linearly to 9 for 90°F, and to 1 for 100°F or hotter.
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 Kimberley typically lasts for 9.1 months (278 days), from around August 23 to around May 28, rarely starting before July 28 or after September 15, and rarely ending before April 29 or after June 25.
Time Spent in Various Temperature Bands and the Growing Season
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.
Based on growing degree days alone, the first spring blooms in Kimberley should appear around July 21, only rarely appearing before July 16 or after July 25.

Temperature and Dew Point
There is only a single weather station, Kimberly Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Kimberley.
At a distance of 8 kilometers from Kimberley, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.
The station records are corrected for the elevation difference between the station and Kimberley according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.
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.
