For reference, the year's highest daily chance of a wet day is 44% on January 1, and its lowest chance is 2% on August 9. RainfallTo show variation within the month and not just the monthly total, we show the rainfall accumulated over a sliding 31-day period centered around each day. The average sliding 31-day rainfall during September in Serrezuela is increasing, starting the month at 0.5 inches, when it rarely exceeds 1.3 inches, and ending the month at 1.0 inches, when it rarely exceeds 2.3 inches or falls below 0.1 inches. SunOver the course of September in Serrezuela, the length of the day is increasing. From the start to the end of the month, the length of the day increases by 53 minutes, implying an average daily increase of 1 minute, 49 seconds, and weekly increase of 12 minutes, 44 seconds. The shortest day of the month is September 1, with 11 hours, 30 minutes of daylight and the longest day is September 30, with 12 hours, 23 minutes of daylight. The latest sunrise of the month in Serrezuela is 7:36 AM on September 1 and the earliest sunrise is 36 minutes earlier at 7:00 AM on September 30. The earliest sunset is 7:06 PM on September 1 and the latest sunset is 16 minutes later at 7:22 PM on September 30. Daylight saving time is not observed in Serrezuela during 2024. For reference, on December 21, the longest day of the year, the Sun rises at 6:15 AM and sets 14 hours, 8 minutes later, at 8:23 PM, while on June 20, the shortest day of the year, it rises at 8:18 AM and sets 10 hours, 10 minutes later, at 6:28 PM. The figure below presents 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. MoonThe figure below presents a compact representation of key lunar data for September 2024. 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.
HumidityWe 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 chance that a given day will be muggy in Serrezuela is essentially constant during September, remaining within 1% of 1% throughout. For reference, on February 22, the muggiest day of the year, there are muggy conditions 53% of the time, while on July 13, the least muggy day of the year, there are muggy conditions 0% of the time. WindThis 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 Serrezuela is gradually increasing during September, increasing from 7.7 miles per hour to 8.7 miles per hour over the course of the month. For reference, on November 6, the windiest day of the year, the daily average wind speed is 8.8 miles per hour, while on June 13, the calmest day of the year, the daily average wind speed is 5.9 miles per hour. The hourly average wind direction in Serrezuela throughout September is predominantly from the east, with a peak proportion of 49% on September 29. Growing SeasonDefinitions 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 Serrezuela typically lasts for 11 months (328 days), from around July 27 to around June 21, rarely starting after August 26, or ending before May 21. The month of September in Serrezuela is more likely than not fully outside of the growing season, with the chance that a given day is in the growing season gradually increasing from 94% to 100% over the course of the month. 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. The average accumulated growing degree days in Serrezuela are increasing during September, increasing by 438°F, from 503°F to 940°F, over the course of the month. Solar EnergyThis 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 in Serrezuela is increasing during September, rising by 1.1 kWh, from 4.8 kWh to 6.0 kWh, over the course of the month.

Data SourcesThis report illustrates the typical weather in Serrezuela, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Temperature and Dew PointThere are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Serrezuela. For each station, the records are corrected for the elevation difference between that station and Serrezuela 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 Serrezuela is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Serrezuela and a given station. The stations contributing to this reconstruction are:
To get a sense of how much these sources agree with each other, you can view a comparison of Serrezuela and the stations that contribute to our estimates of its temperature history and climate. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data. Other DataAll 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.

Weather data is prone to errors, outages, and other defects. We assume no responsibility for any decisions made on the basis of the content presented on this site. 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.
