The figure below presents a compact representation of key lunar data for 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. 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 4. The month with the most muggy days in Memphis is July , with The month with the fewest muggy days in Memphis is January , with 0. 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.

To characterize how pleasant the weather is in Memphis throughout the year, we compute two travel scores.

Based on this score, the best time of year to visit Memphis for hot-weather activities is from early June to mid September , with a peak score in the last week of August. 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 Memphis typically lasts for 8. 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 Memphis should appear around February 13 , only rarely appearing before January 29 or after March 2. Climate Past Weather Predictions.
