Best Time of Year to Visit
To characterize how pleasant the weather is in Hallsville 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 times of year to visit Hallsville for general outdoor tourist activities are from mid April to mid June and from early September to mid October, with a peak score in the first week of October.
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 Hallsville for hot-weather activities is from late May to mid September, with a peak score in the last week of June.
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.

Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Hallsville.
For each station, the records are corrected for the elevation difference between that station and Hallsville 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 Hallsville is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Hallsville and a given station.
The stations contributing to this reconstruction are: Gregg County Airport (52%, 19 kilometers, southwest); Harrison County Airport (33%, 25 kilometers, east); and Gilmer, Fox Stephens Field - Gilmer Municipal Airport (16%, 41 kilometers, northwest).
