Sun Elevation and Azimuth
The figures below present a compact representation of the sun's elevation (the angle of the sun above the horizon) and azimuth (its compass bearing) for every hour of every day in the reporting period. The horizontal axis is the day of the year and the vertical axis is the hour of the day. For a given day and hour of that day, the background color indicates the azimuth of the sun at that moment. The black isolines are contours of constant solar elevation.
The black lines are lines of constant solar elevation (the angle of the sun above the horizon, in degrees). The background color fills indicate the azimuth (the compass bearing) of the sun. The lightly tinted areas at the boundaries of the cardinal compass points indicate the implied intermediate directions (northeast, southeast, southwest, and northwest).
Lunar Data
The figure below presents a compact representation of key lunar data for July 2025. The horizontal axis is the day, the vertical axis is the hour of the day, and the colored areas indicate when the moon is above the horizon. The vertical gray bars (new Moons) and blue bars (full Moons) indicate key Moon phases. The label associated with each bar indicates the date and time that the phase is obtained, and the companion time labels indicate the rise and set times of the Moon for the nearest time interval in which the moon is above the horizon.
Humidity
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.
Lagos
The chance that a given day will be muggy in Lagos is essentially constant during July, remaining around 100% throughout. For reference, on April 8, the muggiest day of the year, there are muggy conditions 100% of the time, while on January 16, the least muggy day of the year, there are muggy conditions 84% of the time.
Enugu
The chance that a given day will be muggy in Enugu is essentially constant during July, remaining around 100% throughout. For reference, on April 11, the muggiest day of the year, there are muggy conditions 100% of the time, while on January 1, the least muggy day of the year, there are muggy conditions 32% of the time.
Wind
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.
Lagos
The average hourly wind speed in Lagos is gradually increasing during July, increasing from 8.2 miles per hour to 9.0 miles per hour over the course of the month. For reference, on July 31, the windiest day of the year, the daily average wind speed is 9.0 miles per hour, while on December 16, the calmest day of the year, the daily average wind speed is 4.7 miles per hour. The highest daily average wind speed during July is 9.0 miles per hour on July 31.
The hourly average wind direction in Lagos throughout July is predominantly from the west, with a peak proportion of 68% on July 23.
Enugu
The average hourly wind speed in Enugu is gradually increasing during July, increasing from 7.0 miles per hour to 7.6 miles per hour over the course of the month. For reference, on August 2, the windiest day of the year, the daily average wind speed is 7.6 miles per hour, while on November 16, the calmest day of the year, the daily average wind speed is 4.2 miles per hour.
The hourly average wind direction in Enugu throughout July is predominantly from the west, with a peak proportion of 75% on July 29.
The percentage of hours in which the mean wind direction is from each of the four cardinal wind directions, excluding hours in which the mean wind speed is less than 1.0 mph. The lightly tinted areas at the boundaries are the percentage of hours spent in the implied intermediate directions (northeast, southeast, southwest, and northwest).
Surface Water Temperature (Lagos)
Lagos is located near a large body of water (e.g., ocean, sea, or large lake). The average surface water temperature in Lagos is gradually decreasing during July, falling by 3°F, from 80°F to 78°F, over the course of the month.
Growing Season
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 Lagos and Enugu are sufficiently warm year round that it is not entirely meaningful to discuss the growing season in these terms.
Growing Degree Days
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.
Lagos
The average accumulated growing degree days in Lagos are rapidly increasing during July, increasing by 853°F, from 5,789°F to 6,642°F, over the course of the month.
Enugu
The average accumulated growing degree days in Enugu are rapidly increasing during July, increasing by 763°F, from 4,939°F to 5,702°F, over the course of the month.
The average growing degree days accumulated over the course of July, with 25th to 75th and 10th to 90th percentile bands.
Solar Energy
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.

Data Sources and Methodology
This report illustrates the typical weather in Lagos and Enugu, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Lagos
There is only a single weather station, Murtala Mohammed International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Lagos. At a distance of 16 kilometers from Lagos, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records. The station records are corrected for the elevation difference between the station and Lagos according to the International Standard Atmosphere, and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.
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.
Enugu
Enugu 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 Enugu, 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 Algorithms 2nd Edition, 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. 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. Time zones for airports and weather stations are provided by AskGeo.com.

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.
