Solar elevation and azimuth over the course of July 2026. 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).
MoonThe figure below presents a compact representation of key lunar data for July 2026. 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.

Moon Rise, Set & Phases in July in Baton Rouge
The time in which the moon is above the horizon (light blue area), with new moons (dark gray lines) and full moons (blue lines) indicated. The shaded overlays indicate night and civil twilight.
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 Baton Rouge is essentially constant during July, remaining within 1% of 98% throughout. The highest chance of a muggy day during July is 99% on July 23. For reference, on July 22, the muggiest day of the year, there are muggy conditions 99% of the time, while on January 29, the least muggy day of the year, there are muggy conditions 4% 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 Baton Rouge is essentially constant during July, remaining within 0.2 miles per hour of 4.8 miles per hour throughout. For reference, on February 25, the windiest day of the year, the daily average wind speed is 7.7 miles per hour, while on August 8, the calmest day of the year, the daily average wind speed is 4.6 miles per hour. The wind direction in Baton Rouge during July is predominantly out of the south from July 1 to July 20 and the west from July 20 to July 31. Wind Direction in July in Baton Rouge
northeastsouthwest
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).
Water TemperatureBaton Rouge 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 surface water temperature in Baton Rouge is essentially constant during July, remaining within 1°F of 85°F throughout. 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 Baton Rouge typically lasts for 9.5 months (287 days), from around February 20 to around December 4, rarely starting before January 24 or after March 18, and rarely ending before November 11 or after December 26. The month of July in Baton Rouge is reliably fully within the growing season. Time Spent in Various Temperature Bands and the Growing Season in July in Baton Rouge

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 Baton Rouge are very rapidly increasing during July, increasing by 907°F, from 2,981°F to 3,888°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 Baton Rouge is essentially constant during July, remaining within 0.1 kWh of 5.7 kWh throughout. TopographyFor the purposes of this report, the geographical coordinates of Baton Rouge are 30.451 deg latitude, -91.155 deg longitude, and 46 ft elevation. The topography within 2 miles of Baton Rouge is essentially flat, with a maximum elevation change of 43 feet and an average elevation above sea level of 47 feet. Within 10 miles is essentially flat (118 feet). Within 50 miles also contains only modest variations in elevation (440 feet).

Data SourcesThis report illustrates the typical weather in Baton Rouge, 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 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Baton Rouge. For each station, the records are corrected for the elevation difference between that station and Baton Rouge 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 Baton Rouge is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Baton Rouge 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 Baton Rouge 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.
