RainfallTo show variation within the season and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day. The average sliding 31-day rainfall during the summer in Tarumizu is very rapidly decreasing, starting the season at 12.5 inches, when it rarely exceeds 21.3 inches or falls below 5.8 inches, and ending the season at 7.9 inches, when it rarely exceeds 15.5 inches or falls below 2.6 inches. The highest average 31-day accumulation is 16.8 inches on June 20. SunOver the course of the summer in Tarumizu, the length of the day is rapidly decreasing. From the start to the end of the season, the length of the day decreases by 1 hour, 14 minutes, implying an average daily decrease of 49 seconds, and weekly decrease of 5 minutes, 43 seconds. The shortest day of the summer is August 31, with 12 hours, 50 minutes of daylight and the longest day is June 21, with 14 hours, 12 minutes of daylight. The earliest sunrise of the summer in Tarumizu is 5:11 AM on June 11 and the latest sunrise is 40 minutes later at 5:52 AM on August 31. The latest sunset is 7:26 PM on June 30 and the earliest sunset is 44 minutes earlier at 6:42 PM on August 31. Daylight saving time is not observed in Tarumizu during 2024.

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 the summer of 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 Tarumizu is very rapidly increasing during the summer, rising from 38% to 94% over the course of the season. The highest chance of a muggy day during the summer is 100% on August 6. For reference, on August 4, the muggiest day of the year, there are muggy conditions 100% of the time, while on December 25, 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 Tarumizu is essentially constant during the summer, remaining within 0.5 miles per hour of 10.4 miles per hour throughout. For reference, on February 3, the windiest day of the year, the daily average wind speed is 12.8 miles per hour, while on September 18, the calmest day of the year, the daily average wind speed is 9.7 miles per hour. The highest daily average wind speed during the summer is 10.8 miles per hour on June 26. The wind direction in Tarumizu during the summer is predominantly out of the east from June 1 to June 9 and from August 3 to August 31 and the west from June 9 to August 3. Water TemperatureTarumizu 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 Tarumizu is rapidly increasing during the summer, rising by 9°F, from 73°F to 82°F, over the course of the season. The highest average surface water temperature during the summer is 83°F on August 17. 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 Tarumizu typically lasts for 9.7 months (295 days), from around February 26 to around December 17, rarely starting before February 1 or after March 16, and rarely ending before November 28 or after January 4. The summer in Tarumizu is reliably fully within the growing season. 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 Tarumizu are very rapidly increasing during the summer, increasing by 2,630°F, from 1,269°F to 3,899°F, over the course of the season.

Data SourcesThis report illustrates the typical weather in Tarumizu, 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 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Tarumizu. For each station, the records are corrected for the elevation difference between that station and Tarumizu 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 Tarumizu is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Tarumizu 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 Tarumizu 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.
