In Wete, the wet season is mostly cloudy; the dry season is mostly clear; and it is warm, oppressive, and windy year round. Over the course of the year, the temperature typically varies from 72°F to 86°F and is rarely below 70°F or above 88°F.

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 Wete, the average percentage of the sky covered by clouds experiences significant seasonal variation over the course of the year.

The clearer part of the year in Wete begins around May 20 and lasts for 5.5 months, ending around November 5. On September 1, the clearest day of the year, the sky is clear, mostly clear, or partly cloudy 76% of the time, and overcast or mostly cloudy 24% of the time.

The cloudier part of the year begins around November 5 and lasts for 6.5 months, ending around May 20. On March 16, the cloudiest day of the year, the sky is overcast or mostly cloudy 71% of the time, and clear, mostly clear, or partly cloudy 29% 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 Wete varies very significantly throughout the year.

The wetter season lasts 2.3 months, from March 20 to May 28, with a greater than 33% chance of a given day being a wet day. The chance of a wet day peaks at 62% on April 21.

The drier season lasts 9.7 months, from May 28 to March 20. The smallest chance of a wet day is 4% on August 29.

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 62% on April 21.

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. Wete experiences extreme seasonal variation in monthly rainfall.

The rainy period of the year lasts for 9.6 months, from September 26 to July 13, 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 6.1 inches.

The rainless period of the year lasts for 2.4 months, from July 13 to September 26. The least rain falls around September 6, with an average total accumulation of 0.3 inches.

The length of the day in Wete does not vary substantially over the course of the year, staying within 25 minutes of 12 hours throughout. In 2017, the shortest day is June 21, with 11 hours, 50 minutes of daylight; the longest day is December 21, with 12 hours, 25 minutes of daylight.

The earliest sunrise is at 5:55 AM on November 11, and the latest sunrise is 36 minutes later at 6:31 AM on July 19. The earliest sunset is at 6:12 PM on October 22, and the latest sunset is 31 minutes later at 6:44 PM on February 1.

Daylight saving time (DST) is not observed in Wete 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 Wete, 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 100% 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 Wete experiences significant seasonal variation over the course of the year.

The windier part of the year lasts for 5.0 months, from April 26 to September 27, with average wind speeds of more than 7.0 miles per hour. The windiest day of the year is June 25, with an average hourly wind speed of 9.3 miles per hour.

The calmer time of year lasts for 7.0 months, from September 27 to April 26. The calmest day of the year is March 25, with an average hourly wind speed of 4.7 miles per hour.

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

The wind is most often from the south for 6.6 months, from April 2 to October 22, with a peak percentage of 100% on June 24. The wind is most often from the east for 5.3 months, from October 22 to April 2, with a peak percentage of 52% on January 1.

Wete is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water.

The average water temperature experiences some seasonal variation over the course of the year.

The time of year with warmer water lasts for 2.2 months, from February 24 to April 29, with an average temperature above 83°F. The day of the year with the warmest water is March 28, with an average temperature of 85°F.

The time of year with cooler water lasts for 3.1 months, from July 4 to October 6, with an average temperature below 79°F. The day of the year with the coolest water is August 15, with an average temperature of 78°F.

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 some seasonal variation over the course of the year.

The brighter period of the year lasts for 2.3 months, from August 30 to November 9, with an average daily incident shortwave energy per square meter above 6.8 kWh. The brightest day of the year is October 6, with an average of 7.2 kWh.

Temperature and Dew Point

There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Wete.

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

The stations contributing to this reconstruction are: Mombasa Airport (58%, 115 kilometers, north) and Abeid Amani Karume International Airport (42%, 141 kilometers, southwest).

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.

Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database .
