Dallas Love Field · daily data Aug 1, 1939 – Sep 29, 2026
87 years of Dallas weather
Hot, and getting hotter. Dallas has reached 112 °F and fallen to 0 °F. A normal year has about 20 days of 100 °F or more and 38 inches of rain, but single years have brought 73 such days and anywhere from 18 to 68 inches. Through it all the city has warmed by about 0.4 °F a decade.
Every chart on this page is drawn from one file: the 31,837 daily readings (high, low, rain, snow, wind and thunder) taken at Dallas Love Field since August 1939 and published by NOAA. Each is a Holochart example that runs live in your browser and doubles as a visual regression test. Drag to zoom, hover for the day's numbers, and use the toggles above a chart to switch what it shows. Love Field is not the official Dallas/Fort Worth station (that is DFW Airport, 25 km west), so a record here can differ by a degree or two from the one in the news.
2026 so far
The year through Sep 29, 2026 against the 1991–2020 average for the same part of the year: 54 days of 100 °F or more, a hottest day of 109 °F and 23.7 inches of rain.
Each bar is one day, from its low to its high, over the usual range for that date (darker band) and the record range (pale band). Switch the year to see the summers of 1980 and 2011 or the freeze of February 2021.
The same year as a calendar, one square per day, colored by the high.
The whole record
Every daily high and low since 1939 in one chart, more than 63,000 points. It opens on the last five years; drag the slider or use the buttons to move between one year and the whole record.
Each year's hottest day and coldest night. The hottest day is much the same every year; the coldest night is not.
The record book
The ten hottest days, coldest nights and wettest days. The wettest brought 6.90 inches on Mar 19, 2006.
Heat
Days of 100 °F or more in each year. 2011 had 73 and 1980 had 70; some years have none. Switch to freezing nights for the other end of the thermometer.
The longest unbroken runs of 100 °F days.
Every 100 °F day on record, grouped by decade and year. The area of a tile is the number of such days that year.
Four famous spells
The freeze of February 2021, the summers of 1980 and 2011, and the cold of December 1983, day by day against what is normal for those dates.
The seasons
The normal year: two wet seasons, in May and October, and a dry, hot July and August.
The year as a clock, with January at the top: the average high and low of every calendar day, and the records outside and inside them. Record lows stray much further from the average than record highs.
The spread of daily highs in each month. A January day can be almost anything; a July day is nearly always in the 90s.
Every day of the record by its low and its high. Summer days bunch together in one bright patch, while cool-season days spread widely.
Every day sorted by season, by how warm it got, and by whether it rained.
The freeze-free season
The last freeze of spring and the first of fall in each year, with the growing season between them.
Getting warmer
One stripe per year, blue if cooler and red if warmer than the long-run average.
The same numbers as bars, with a ten-year average and the trend: about 0.39 °F per decade.
Every month since 1940. Switch to "Difference from normal" to take the seasons out and see the unusual months.
Daily highs in the first and the last 30 years of the record. The whole distribution has moved to the right.
Summer afternoons and winter nights by decade.
Which part of the year warmed
The average high through the year for three 30-year periods, and the change from the first to the last.

The record in 3D
86 years of weekly highs as a landscape. Every year is one wave, so the summers line up as a ridge running through the decades. Drag to turn it.
Every month since 1940 as a spiral, once round per year, pushed outward when the month was warmer than normal. Single months swing far more than the climate has shifted, so the widening toward the top is faint.
Rain
Rain per year. 2015 was the wettest with 68.0 inches and 1963 the driest with 17.5. The years 1997 and 1998 are left out because the rain record has gaps.
Each line is one year's rain adding up from January 1. Flat stretches are dry spells and jumps are storms.
Rain of every month since 1940.
A normal year of rain
How a normal year adds up, month by month.
The same year by season. Click a season to zoom in.
Average monthly rain in each decade: the May and October ridges and the summer valley run through all of them.
How it rains
Most rainy days bring little: more than half have under a quarter inch.
It rains on about one day in five, and heavy rain is rare.
Dry spells
The twelve longest runs of days without measurable rain. Most began in summer.
Dry summers are hot summers: each summer's rain against its average afternoon high.
Storms, snow and wind
Days with thunder in each month. Spring is storm season.
Snowfall per winter. Many winters have none; the shaded years have no snowfall record.
Wind
Where the day's strongest wind comes from, since 1997: mostly the south, and the north behind cold fronts. Switch the season to see the winter northers.
One dot per day, more than 10,000 of them, placed by the direction and speed of the day's fastest wind.
Spring is also the windy season.
Years compared
Each line is one year across seven measures. Drag along an axis to pick out years; the recent ones (red) run warmer, with fewer freezes.
Four yearly measures against each other. Warm years have fewer freezing nights, and dry years have more 100 °F days.
