Climate overview
Temperature
Monthly mean temperatures peak at July with 30.0 °C, while the coolest monthly mean is January at 8.3 °C. These are averages for each month, not daytime highs, so they describe the broad temperature pattern rather than the range a visitor may experience within a day. The unweighted mean of the monthly temperature means is 19.4 °C; it summarizes the calendar-month averages without weighting them by the number of days in each month.
Rain
Mean daily rainfall is highest in May at 5.67 mm/day and lowest in July at 1.89 mm/day. These are daily mean amounts, not monthly totals, and the lower average does not mean that every day in that month is dry. Across the calendar months, the unweighted mean of monthly mean daily rainfall is 3.53 mm/day. This provides an overall summary, but does not describe how rainfall is distributed from day to day.
Sunshine
Daily mean sunshine reaches its highest level in July at 12.01 hours/day, and its lowest in December at 6.43 hours/day. These figures describe average sunshine duration, not day length, and the unweighted mean across monthly averages is 8.90 hours/day.
Best Travel Time Guide for dallas, USA: Ideal Seasons and Weather Insights
If lower average rainfall is your priority, July is the option indicated by the lowest monthly mean daily rainfall, 1.89 mm/day. That average cannot guarantee dry days or tell you how often rain occurs, so keep plans flexible and check the forecast close to travel. For rain preparation, note that May has the highest monthly mean daily rainfall at 5.67 mm/day; consider packing a lightweight rain layer rather than treating the average as a prediction for any particular day.
Visitors prioritising cooler monthly averages can look to January, when the monthly mean temperature is 8.3 °C. It is an average, not a daytime high or a guarantee of the conditions during a visit, so check the forecast and pack for variable temperatures. For outdoor sightseeing planned around sunshine duration, July has the highest daily mean at 12.01 hours/day, while December has the lowest at 6.43 hours/day. Sunshine hours are not day length, and these different criteria do not establish one universally best time to visit.
