A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Marneuli varies throughout the year.
The wetter season lasts 3.0 months, from April 6 to July 4, with a greater than 16% chance of a given day being a wet day. The chance of a wet day peaks at 26% on April 30.
The drier season lasts 9.0 months, from July 4 to April 6. The smallest chance of a wet day is 6% on January 11.
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 26% on April 30.
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. Marneuli experiences some seasonal variation in monthly rainfall.

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.
Marneuli experiences some seasonal variation in the perceived humidity.
The muggier period of the year lasts for 3.5 months, from June 8 to September 24, during which time the comfort level is muggy, oppressive, or miserable at least 4% of the time. The muggiest day of the year is July 23, with muggy conditions 18% of the time.
The least muggy day of the year is December 5, when muggy conditions are essentially unheard of.

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 Marneuli experiences mild seasonal variation over the course of the year.
The windier part of the year lasts for 8.1 months, from January 17 to September 22, with average wind speeds of more than 6.0 miles per hour. The windiest day of the year is March 12, with an average hourly wind speed of 7.0 miles per hour.
The calmer time of year lasts for 3.9 months, from September 22 to January 17. The calmest day of the year is November 28, with an average hourly wind speed of 5.1 miles per hour.
Average Wind Speed
The predominant average hourly wind direction in Marneuli varies throughout the year.
The wind is most often from the east for 8.7 months, from February 23 to November 14, with a peak percentage of 61% on July 27. The wind is most often from the west for 3.3 months, from November 14 to February 23, with a peak percentage of 57% on January 1.
Best Time of Year to Visit
To characterize how pleasant the weather is in Marneuli 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 Marneuli for general outdoor tourist activities are from late May to early July and from mid August to late September, with a peak score in the second week of September.
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 Marneuli for hot-weather activities is from late June to late August, with a peak score in the last week of July.
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 Marneuli typically lasts for 8.0 months (245 days), from around March 19 to around November 19, rarely starting before March 1 or after April 9, and rarely ending before October 31 or after December 9.

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 Marneuli should appear around March 28, only rarely appearing before March 10 or after April 14.

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 19 to August 21, with an average daily incident shortwave energy per square meter above 6.3 kWh. The brightest day of the year is July 5, with an average of 7.4 kWh.

Temperature and Dew Point
There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Marneuli.
For each station, the records are corrected for the elevation difference between that station and Marneuli 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 Marneuli is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Marneuli and a given station.
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.
