For reference, the year's highest daily chance of a wet day is 15% on May 27, and its lowest chance is 7% on September 25. 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 June in San Julián is essentially constant, remaining about 0.8 inches throughout, and rarely exceeding 1.9 inches or falling below 0.1 inches. The highest average 31-day accumulation is 0.9 inches on June 3. SunOver the course of June in San Julián, the length of the day is essentially constant. The shortest day of the month is June 20, with 8 hours, 11 minutes of daylight and the longest day is June 1, with 8 hours, 26 minutes of daylight. The earliest sunrise of the month in San Julián is 9:15 AM on June 1 and the latest sunrise is 12 minutes later at 9:27 AM on June 25. The earliest sunset is 5:37 PM on June 15 and the latest sunset is 5 minutes later at 5:42 PM on June 30. Daylight saving time is not observed in San Julián during 2024. For reference, on December 21, the longest day of the year, the Sun rises at 5:21 AM and sets 16 hours, 16 minutes later, at 9:37 PM, while on June 20, the shortest day of the year, it rises at 9:27 AM and sets 8 hours, 11 minutes later, at 5:38 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 June 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 San Julián is essentially constant during June, remaining around 0% throughout. 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 San Julián is essentially constant during June, remaining within 0.2 miles per hour of 15.4 miles per hour throughout. For reference, on December 8, the windiest day of the year, the daily average wind speed is 15.7 miles per hour, while on October 1, the calmest day of the year, the daily average wind speed is 14.1 miles per hour. The hourly average wind direction in San Julián throughout June is predominantly from the west, with a peak proportion of 62% on June 19. Water TemperatureSan Julián 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 San Julián is gradually decreasing during June, falling by 3°F, from 47°F to 44°F, over the course of the month. 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 San Julián typically lasts for 7.8 months (236 days), from around September 18 to around May 13, rarely starting before August 24 or after October 15, and rarely ending before April 15 or after June 7. The month of June in San Julián is more likely than not fully outside of the growing season, with the chance that a given day is in the growing season decreasing from 16% to 1% 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 San Julián are essentially constant during June, remaining within 3°F of 1,678°F throughout. 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 San Julián is essentially constant during June, remaining within 0.1 kWh of 1.0 kWh throughout. The lowest average daily incident shortwave solar energy during June is 1.0 kWh on June 22.

Data SourcesThis report illustrates the typical weather in San Julián, 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 is only a single weather station, Capitán José Daniel Vazquez Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of San Julián. At a distance of 5 kilometers from San Julián, 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 San Julián 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. 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.
