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.
Lubbock experiences some seasonal variation in the perceived humidity.
The muggier period of the year lasts for 4.0 months, from May 27 to September 27, during which time the comfort level is muggy, oppressive, or miserable at least 4% of the time. The muggiest day of the year is July 3, with muggy conditions 17% of the time.
The least muggy day of the year is December 9, 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 Lubbock experiences significant seasonal variation over the course of the year.
The windier part of the year lasts for 5.0 months, from January 29 to June 29, with average wind speeds of more than 11.0 miles per hour. The windiest day of the year is April 1, with an average hourly wind speed of 12.9 miles per hour.
The calmer time of year lasts for 7.0 months, from June 29 to January 29. The calmest day of the year is August 25, with an average hourly wind speed of 9.1 miles per hour.
Average Wind Speed
The predominant average hourly wind direction in Lubbock varies throughout the year.
The wind is most often from the south for 8.1 months, from March 10 to November 12, with a peak percentage of 74% on July 21. The wind is most often from the west for 3.9 months, from November 12 to March 10, with a peak percentage of 39% on January 1.
Best Time of Year to Visit
To characterize how pleasant the weather is in Lubbock throughout the year, we compute two travel scores.
The tourism score favors clear, rainless days with perceived temperatures between 65°F and 80°F. Based on this score, the best time of year to visit Lubbock for general outdoor tourist activities is from mid May to early October, with a peak score in the first week of September.
The beach/pool score favors clear, rainless days with perceived temperatures between 75°F and 90°F. Based on this score, the best time of year to visit Lubbock for hot-weather activities is from mid June to late August, with a peak score in the third week of July.
For each hour between 8:00 AM and 9:00 PM of each day in the analysis period (1980 to 2016), 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 0.04 inches of precipitation or more.
Our tourism temperature score is 0 for perceived temperatures below 50°F, rising linearly to 9 for 65°F, to 10 for 75°F, falling linearly to 9 for 80°F, and to 1 for 90°F or hotter.
Our beach/pool temperature score is 0 for perceived temperatures below 65°F, rising linearly to 9 for 75°F, to 10 for 82°F, falling linearly to 9 for 90°F, and to 1 for 100°F or hotter.
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 Lubbock typically lasts for 7.3 months (222 days), from around March 31 to around November 8, rarely starting before March 10 or after April 21, and rarely ending before October 20 or after November 27.

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.
Based on growing degree days alone, the first spring blooms in Lubbock should appear around February 11, only rarely appearing before January 31 or after February 27.

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 4.2 months, from April 8 to August 14, with an average daily incident shortwave energy per square meter above 6.7 kWh. The brightest day of the year is June 11, with an average of 7.6 kWh.
The darker period of the year lasts for 2.9 months, from November 7 to February 4, with an average daily incident shortwave energy per square meter below 4.0 kWh. The darkest day of the year is December 23, with an average of 3.1 kWh.

This report illustrates the typical weather in Lubbock, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Lubbock.
For each station, the records are corrected for the elevation difference between that station and Lubbock 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 Lubbock is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Lubbock and a given station.
The stations contributing to this reconstruction are: Lubbock International Airport (70%, 10 kilometers, north); Reese Air Force Base / Lubbock (29%, 18 kilometers, west); and Winston Field (1.5%, 130 kilometers, southeast).
All 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.

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.
