The figure below shows you a compact characterization of the entire year of hourly average temperatures. The horizontal axis is the day of the year, the vertical axis is the hour of the day, and the color is the average temperature for that hour and day.

In Berri, the average percentage of the sky covered by clouds experiences mild seasonal variation over the course of the year.

The clearer part of the year in Berri begins around July 2 and lasts for 3.7 months, ending around October 25. On September 13, the clearest day of the year, the sky is clear, mostly clear, or partly cloudy 78% of the time, and overcast or mostly cloudy 22% of the time.

The cloudier part of the year begins around October 25 and lasts for 8.3 months, ending around July 2. On June 1, the cloudiest day of the year, the sky is overcast or mostly cloudy 36% of the time, and clear, mostly clear, or partly cloudy 64% of the time.

Berri does not experience significant seasonal variation in the frequency of wet days (i.e., those with greater than 0.04 inches of liquid or liquid-equivalent precipitation). The frequency ranges from 5% to 14%, with an average value of 10%.

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 14% on July 6.

Rainfall

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. Berri experiences some seasonal variation in monthly rainfall.

The rainy period of the year lasts for 11 months, from April 5 to March 8, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around December 7, with an average total accumulation of 0.8 inches.

The rainless period of the year lasts for 4.0 weeks, from March 8 to April 5. The least rain falls around March 26, with an average total accumulation of 0.5 inches.

The length of the day in Berri varies significantly over the course of the year. In 2017, the shortest day is June 21, with 9 hours, 52 minutes of daylight; the longest day is December 21, with 14 hours, 27 minutes of daylight.

The earliest sunrise is at 5:46 AM on September 30, and the latest sunrise is 1 hour, 34 minutes later at 7:19 AM on April 1. The earliest sunset is at 5:04 PM on June 12, and the latest sunset is 3 hours, 19 minutes later at 8:23 PM on January 7.

Daylight saving time (DST) is observed in Berri during 2017, starting in the spring on October 1 and ending in the fall on April 2.

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 Berri, 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 1% of 1% 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 Berri experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 6.8 months, from August 23 to March 16, with average wind speeds of more than 5.3 miles per hour. The windiest day of the year is December 24, with an average hourly wind speed of 6.2 miles per hour.

The calmer time of year lasts for 5.2 months, from March 16 to August 23. The calmest day of the year is May 20, with an average hourly wind speed of 4.5 miles per hour.

The predominant average hourly wind direction in Berri varies throughout the year.

The wind is most often from the north for 3.0 weeks, from May 25 to June 15, with a peak percentage of 30% on June 14. The wind is most often from the west for 3.5 months, from June 15 to September 29, with a peak percentage of 41% on August 10. The wind is most often from the south for 7.9 months, from September 29 to May 25, with a peak percentage of 55% on January 1.

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.

The average daily incident shortwave solar energy experiences extreme seasonal variation over the course of the year.

The brighter period of the year lasts for 3.6 months, from November 2 to February 19, with an average daily incident shortwave energy per square meter above 7.3 kWh. The brightest day of the year is January 4, with an average of 8.5 kWh.

The darker period of the year lasts for 3.4 months, from May 2 to August 15, with an average daily incident shortwave energy per square meter below 3.8 kWh. The darkest day of the year is June 24, with an average of 2.6 kWh.

This report illustrates the typical weather in Berri, 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 is only a single weather station, RAAF Base Edinburgh, in our network suitable to be used as a proxy for the historical temperature and dew point records of Berri.

At a distance of 188 kilometers from Berri, further than our threshold of 150 kilometers, this station is deemed insufficiently nearby to be relied upon as our primary source for temperature and dew point records. Consequently, the station records are blended with interpolated values from NASA's MERRA-2 satellite-era reanalysis , and both are corrected for elevation differences according to the International Standard Atmosphere .

The weight assigned to the MERRA-2 value depends on the distance from Berri to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 43%, making the weight assigned to the weather station 57%.

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , 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.
