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

The clearer part of the year in Sivas begins around June 1 and lasts for 4.0 months, ending around October 1. On August 1, the clearest day of the year, the sky is clear, mostly clear, or partly cloudy 99% of the time, and overcast or mostly cloudy 1% of the time.

The cloudier part of the year begins around October 1 and lasts for 8.0 months, ending around June 1. On December 24, the cloudiest day of the year, the sky is overcast or mostly cloudy 55% of the time, and clear, mostly clear, or partly cloudy 45% of the time.

A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Sivas varies throughout the year.

The wetter season lasts 8.0 months, from October 15 to June 15, with a greater than 16% chance of a given day being a wet day. The chance of a wet day peaks at 29% on May 1.

The drier season lasts 4.0 months, from June 15 to October 15. The smallest chance of a wet day is 3% on August 3.

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 29% on May 1.

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. Sivas experiences some seasonal variation in monthly rainfall.

The rainy period of the year lasts for 9.5 months, from September 17 to July 2, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around May 1, with an average total accumulation of 1.7 inches.

The rainless period of the year lasts for 2.5 months, from July 2 to September 17. The least rain falls around August 14, with an average total accumulation of 0.2 inches.

Snowfall

We report snowfall in liquid-equivalent terms. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. Colder, drier snow tends to be on the higher end of that range and warmer, wetter snow on the lower end.

As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day of the year. Sivas experiences some seasonal variation in monthly liquid-equivalent snowfall.

The snowy period of the year lasts for 3.3 months, from December 6 to March 15, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around January 29, with an average total liquid-equivalent accumulation of 0.3 inches.

The snowless period of the year lasts for 8.7 months, from March 15 to December 6. The least snow falls around July 17, with an average total liquid-equivalent accumulation of 0.0 inches.

The length of the day in Sivas varies significantly over the course of the year. In 2017, the shortest day is December 21, with 9 hours, 21 minutes of daylight; the longest day is June 21, with 14 hours, 59 minutes of daylight.

The earliest sunrise is at 5:03 AM on June 14, and the latest sunrise is 2 hours, 50 minutes later at 7:53 AM on January 5. The earliest sunset is at 5:07 PM on December 8, and the latest sunset is 2 hours, 57 minutes later at 8:04 PM on June 27.

Daylight saving time (DST) is not observed in Sivas during 2017.

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 Sivas, 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, remaining a virtually constant 0% 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 Sivas experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 4.9 months, from November 22 to April 18, with average wind speeds of more than 4.6 miles per hour. The windiest day of the year is February 9, with an average hourly wind speed of 5.5 miles per hour.

The calmer time of year lasts for 7.1 months, from April 18 to November 22. The calmest day of the year is May 25, with an average hourly wind speed of 3.8 miles per hour.

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

The wind is most often from the north for 5.7 months, from April 28 to October 19, with a peak percentage of 85% on July 26. The wind is most often from the south for 6.3 months, from October 19 to April 28, 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 3.0 months, from May 26 to August 27, with an average daily incident shortwave energy per square meter above 7.1 kWh. The brightest day of the year is July 6, with an average of 8.4 kWh.

This report illustrates the typical weather in Sivas, 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 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Sivas.

For each station, the records are corrected for the elevation difference between that station and Sivas 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 Sivas is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Sivas and a given station.

The stations contributing to this reconstruction are: Sivas Airport (93%, 12 kilometers, northwest) and Malatya Erhaç Airport (7%, 173 kilometers, southeast).

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.
