Graphical Climatology of Dallas / Ft Worth: Daily Temperatures and Rainfall, by Year (1948 – Present)
The following is a graphical climatology of Dallas-Fort Worth Int'l Airport Temperatures, precipitation, and various other variables, from 1948 into the present year 2026. Presented are daily climatological overview charts (temperature), annual time-series (temperature and precipitation), “climograms” (hour-by-month depictions of temperature, humidity, winds, fog, blowing sand/dust, and thunderstorms), followed by year-to-year graphs that depict daily max/min temperature, daily mean temperature anomalies, and daily rainfall, . Data were obtained courtesy of the Utah Climate Center and the NWS-Dallas/Fort Worth online site.

Year-To-Year Graphs - Interpretation
The top chart for a given year’s page (accessed by the links below) are “floating-bars” of the year's daily maxima and minima temperatures. Superimposed on the bars are two line traces, the upper one connecting long-term (1948-2020) mean daily maxima, the lower one mean daily minima.
Second chart down depicts the day-to-day mean temperature anomalies (daily mean temperature less the corresponding long-term 1948-2020 climatological mean). Departures extending upward in red from the zero line indicate warmer than average means for the day, those extending downward in blue indicate below average ones. Greatest single-day departure of either sign is -42 F on 15 Feb 2021 (daily temperature range: 14 F/4 F), the second-most, -40 F, on the very next day 16 February (daily temperature range: 18 F/-2 F )
(Note: Clicking on the floating-bar charts a second time after they appear on the screen will enlarge them further).
Year-To-Year Graphs — OLDER YEARS
The third chart down shows the second chart’s daily mean temperature anomalies in deseasonalized (“standardized” or "z-scores") form . Those of plus or minus 3.0 z are the "extremes of the extremes", comprising just 0.23% (or 63 individual days' cases) over the entire DFW history. All but two of these are negatively signed. Greatest positive standardized departure is +3.12 z for 25 Dec 2016 (80 F/69 F daily temperature range), the greatest negative –4.03 z for 24 Aug 1966 (72 F/64 F temperature range, a day with 1.64" rain).
The bottom chart depicts daily precipitation totals, as high as 5.85 inches (24 Sept 2018).
Links To Some Of The More Interesting Year-To-Year Graphs, With Accompanying Notes
The links below depict daily temperature and precipitation patterns for years that were eventful in some way: individual day, months, and annual basis extremes, along with patterns which are just interesting display for their own sake. Dallas- Fort Worth is noteworthy for its great variability in temperature progressions, especially over the non-summer months, and many of the charts linked below, not to mention others not in the list, have visually striking patterns.
Second wettest year in history (55.97"). September and October combined with 28.35".
Annual Mean (69.9 F) surpasses 2006 by 0.5 F for warmest year to date.
Wettest Year to date (62.61"). May records 16.96", most for any calendar month in history.
August (93.4 F) warmest calendar month in history. Warmest Summer (90.5 F).
Warmest year to date (69.4 F).
Driest year (18.97") since 1956 .
Surpasses last year as warmest year to date (68.6 F)
Surpasses 1954 by 0.1 F as warmest year to date (68.3 F).
Great day-to-day variability in daily max temps over Jan & Feb. Mean figure (10.2 F) - highest for any two-month adjacent segment in history.
Minus 1 F on 23 December.
Coldest year in history (63,3 F). Very cold December (34.9 F - 3.8 standard deviations below average).
Striking daily mean temperature departure pattern over course of year.
