The latest sunrise of the fall in Dana is 7:52 AM on November 2 and the earliest sunrise is 59 minutes earlier at 6:53 AM on November 3.

The latest sunset is 7:55 PM on September 1 and the earliest sunset is 2 hours, 39 minutes earlier at 5:17 PM on November 30.

Daylight saving time (DST) starts at 1:00 AM on November 3, 2024, shifting sunrise and sunset to be an hour later.

For reference, on June 20, the longest day of the year, the Sun rises at 6:14 AM and sets 14 hours, 33 minutes later, at 8:47 PM, while on December 21, the shortest day of the year, it rises at 7:34 AM and sets 9 hours, 46 minutes later, at 5:21 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.

The figure below presents a compact representation of key lunar data for the fall 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.

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.

The chance that a given day will be muggy in Dana is very rapidly decreasing during the fall, falling from 42% to 0% over the course of the season.

For reference, on July 25, the muggiest day of the year, there are muggy conditions 67% of the time, while on November 26, the least muggy day of the year, there are muggy conditions 0% of the time.

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.

The average hourly wind speed in Dana is increasing during the fall, increasing from 3.7 miles per hour to 5.1 miles per hour over the course of the season.

For reference, on March 7, the windiest day of the year, the daily average wind speed is 6.1 miles per hour, while on July 31, the calmest day of the year, the daily average wind speed is 3.4 miles per hour.

The wind direction in Dana during the fall is predominantly out of the east from September 1 to September 16, the north from September 16 to November 27, and the west from November 27 to November 30.

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).

The growing season in Dana typically lasts for 6.5 months (198 days), from around April 10 to around October 26, rarely starting before March 23 or after April 29, and rarely ending before October 7 or after November 14.

During the fall in Dana, the chance that a given day is within the growing season is very rapidly decreasing falling from 100% to 0% over the course of the 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 Dana are rapidly increasing during the fall, increasing by 796°F, from 2,810°F to 3,605°F, over the course of the season.

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.

The average daily incident shortwave solar energy in Dana is very rapidly decreasing during the fall, falling by 3.1 kWh, from 5.8 kWh to 2.7 kWh, over the course of the season.
