A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Bolobo varies very significantly throughout the year.
The wetter season lasts 9.0 months, from September 3 to June 1, with a greater than 46% chance of a given day being a wet day. The chance of a wet day peaks at 82% on November 2.
The drier season lasts 3.0 months, from June 1 to September 3. The smallest chance of a wet day is 10% on July 19.
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 82% on November 2.

Sunrise & Sunset with Twilight
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.
Bolobo experiences some seasonal variation in the perceived humidity.
The muggier period of the year lasts for 11 months, from August 20 to July 6, during which time the comfort level is muggy, oppressive, or miserable at least 84% of the time. The muggiest day of the year is April 9, with muggy conditions 100% of the time.
The least muggy day of the year is July 25, with muggy conditions 78% 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 Bolobo experiences mild seasonal variation over the course of the year.
The windier part of the year lasts for 2.8 months, from June 21 to September 16, with average wind speeds of more than 3.1 miles per hour. The windiest day of the year is July 25, with an average hourly wind speed of 3.7 miles per hour.
The calmer time of year lasts for 9.2 months, from September 16 to June 21. The calmest day of the year is November 29, with an average hourly wind speed of 2.6 miles per hour.
Average Wind Speed
The predominant average hourly wind direction in Bolobo varies throughout the year.
The wind is most often from the south for 3.9 months, from January 1 to April 27 and for 3.6 weeks, from June 1 to June 26, with a peak percentage of 47% on March 9. The wind is most often from the east for 1.1 months, from April 27 to June 1 and for 1.5 months, from November 18 to January 1, with a peak percentage of 40% on May 11. The wind is most often from the west for 3.0 months, from June 26 to September 27, with a peak percentage of 64% on August 12.
Best Time of Year to Visit
To characterize how pleasant the weather is in Bolobo 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 time of year to visit Bolobo for general outdoor tourist activities is from early June to early August, with a peak score in the first week of July.
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 Bolobo for hot-weather activities is from early June to mid August, with a peak score in the second 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).
Temperatures in Bolobo are sufficiently warm year round that it is not entirely meaningful to discuss the growing season in these terms. We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year.
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.
Growing Degree Days
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 per square meter does not vary significantly over the course of the year, remaining within 0.2 kilowatt-hours of 4.8 kilowatt-hours throughout.

This report illustrates the typical weather in Bolobo, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Bolobo is further than 200 kilometers from the nearest reliable weather station, so the weather-related data on this page were taken entirely from NASA's MERRA-2 satellite-era reanalysis . 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.
The temperature and dew point estimates are corrected for the difference between the reference elevation of the MERRA-2 grid cell and the elevation of Bolobo, according to the International Standard Atmosphere .
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.
Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.

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.
