The length of the day in Fall Branch varies significantly over the course of the year. In , the shortest day is December 21 , with 9 hours, 40 minutes of daylight; the longest day is June 20 , with 14 hours, 39 minutes of daylight. The earliest sunrise is at AM on June 12 , and the latest sunrise is 1 hour, 47 minutes later at AM on November 6.

The vertical gray bars new Moons and blue bars full Moons indicate key Moon phases. 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 muggier period of the year lasts for 3. The month with the most muggy days in Fall Branch is July , with The least muggy day of the year is February 11 , when muggy conditions are essentially unheard of. 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 Fall Branch experiences significant seasonal variation over the course of the year. The windier part of the year lasts for 6. The windiest month of the year in Fall Branch is February , with an average hourly wind speed of 6.

The calmer time of year lasts for 5. The calmest month of the year in Fall Branch is August , with an average hourly wind speed of 3. The wind is most often from the south for 4. The wind is most often from the west for 7. To characterize how pleasant the weather is in Fall Branch throughout the year, we compute two travel scores. Based on this score, the best time of year to visit Fall Branch for general outdoor tourist activities is from early June to late September , with a peak score in the first week of September.

Based on this score, the best time of year to visit Fall Branch for hot-weather activities is from late June to early September , with a peak score in the last week of July. For each hour between AM and PM of each day in the analysis period to , independent scores are computed for perceived temperature, cloud cover, and total precipitation.

Those scores are combined into a single hourly composite score, which is then aggregated into days, averaged over all the years in the analysis period, and smoothed.

Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for fully overcast skies.

Our precipitation score , which is based on the three-hour precipitation centered on the hour in question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 0.

The growing season in Fall Branch typically lasts for 6. 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. Based on growing degree days alone, the first spring blooms in Fall Branch should appear around March 13 , only rarely appearing before March 1 or after March 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 experiences significant seasonal variation over the course of the year. The brighter period of the year lasts for 4.

The brightest month of the year in Fall Branch is June , with an average of 6. The darker period of the year lasts for 3. The darkest month of the year in Fall Branch is December , with an average of 2.

For the purposes of this report, the geographical coordinates of Fall Branch are The topography within 2 miles of Fall Branch contains significant variations in elevation, with a maximum elevation change of feet and an average elevation above sea level of 1, feet.

Looking to the future, fall is likely to only get hotter for everyone with the Southwest leading the way. Researching and reporting the science and impacts of climate change.

Changing winter temperatures directly influence the amount of snow that falls and accumulates, amount of seasonal snowpack, timing of snowmelt runoff, loss of soil moisture through evapotranspiration, and amount of time that lakes are frozen see the Snowfall , Snowpack , and Lake Ice indicators.

Warming in other seasons can also affect daily life in various ways. For example, warmer spring and fall temperatures extend the growing season see the Length of Growing Season indicator , which can benefit some forms of agriculture but also lead to a longer and more intense pollen season for allergy sufferers see the Ragweed Pollen Season indicator. These changes could also extend the wildfire season. A warmer summer likely means more money spent on air conditioning, while a warmer winter could mean less money spent on home heating see the Heating and Cooling Degree Days indicator.

Seasonal warming could also disrupt the timing of events that are important for plants and animals, such as budding, flower blooms, hibernation, egg-laying, hatching, and migration. This indicator examines changes in average temperatures in each season, defined here by calendar month for example, winter is December, January, and February.

The indicator is based on daily temperature measurements from more than 10, weather stations located across the contiguous 48 states. Starting in , this indicator shows annual anomalies, or differences, compared with the long-term average seasonal temperatures from to Figure 1.

Anomalies have been calculated for each weather station. Daily temperature measurements at each site were used to calculate monthly anomalies, which were then averaged for each season to find temperature anomalies for each year. Average anomalies are calculated for areas within each state based on station density and proximity, as well as the topography of the area.

These sub-state-level anomalies are then averaged together in proportion to their area to develop state and national results. Data from the early part of the time period are somewhat less precise than more recent data because there were fewer stations collecting measurements at the time. The overall trends are still reliable, however. Where possible, the data have been adjusted to account for any biases that might be introduced by factors such as station moves, urbanization near the station, changes in measuring instruments, and changes in the exact times at which measurements are taken.
