March Temperatures
March’s 10-year temperature average is 62.74°F, a little warmer than the average November. (Occasionally, March is cooler than the same year’s November, though not by much.) The warmest March on record for Central Texas was in 2012, but that was surpassed by March 2017 with an average of 68.0°F. I couldn’t find when the coldest March was, but the coolest recent one was in 2014, averaging 58.44°F.
According to a variety of sources I searched, the coldest temperature ever recorded in March was 17°F, on March 3, 2014, while the warmest temperature March has ever seen was 93°F, on March 11, 1967. During my 13-year record-keeping period (2010-22), the warmest March day was March 26, 2022, hitting 93°F. Only three daily record lows occurred during the past 13 years, compared to 15 daily record highs.
March averages 1.0 freezing days per year — days in which the low is 32°F or cooler — the least of the five months that ever see freezing days. Sixty percent of the time, March does not see freezing days.

Precipitation
Rainfall in March varies from none (0.02 inches in 2011) to 10.73 inches (2012), with no discernable pattern.
March averages 9.27 days per month that exhibit precipitation, with a maximum of 15 days (2020) and a minimum of one (2011).
Trends And Patterns
In the eleven years I’ve been keeping track, March’s temperatures seem to follow a regular up-and-down pattern — a couple of years rising and then a couple of years falling (with minor aberrations). It is also a fairly good predictor of the whole year’s outcome. If March is warmer than average, the whole year will be, and vice versa. (This is true for nine of the ten years I’ve covered — the exception being 2018.)
But March’s precipitation is not related to the overall year, nor the surrounding months.
There is only a slight correlation between rainfall and temperature: if the month is warm, it tends to have more precipitation — but this doesn’t always hold true.
