Temperature trend lines for June, 2010-2017.
(Copyright © 2017 by Wil C. Fry. Some rights reserved.)
June 2017 was cooler than the eight-year average for June, and cooler than the previous June. In fact, of the eight Junes I have lived in Killeen, Texas, the latter four have been cooler than the first four. June was the first month of 2017 that was cooler than the same month in 2016. (May and June were both cooler than average, while January through April were all warmer than average.) June 2011 remains the warmest June in local history, with June 2012 running a close second.
Our high for the month was 102°F, which is about average. Our low for the month was 69°F, which is remarkable — the first time June’s low has been so warm. This is part of the ongoing trend of our lows getting warmer (the area doesn’t cool off as quickly at night as it used to), while our highs have stagnated. It’s the third month this year in which the monthly low was higher than it’s ever been.
We set one daily record this June, 102°F on June 23. Again, we did not set any record lows.
I measured 3.91 inches of rainfall for June 2017, the second-most of the last eight Junes, and the second-highest monthly total in 2017 (behind April). Nine separate days saw precipitation, which is well above average for June. Our rain was spread equally through the month, so our lawn has stayed green without any help from me.
Despite the cooler-than-average* May and June, 2017 is still on track to beat 2012 as our hottest year on record, because of our very warm beginning (our combined January-thru-April HLA has never been this warm).
(* Note: these “averages” are only for the past eight years, during which I’ve kept meticulous records. Based on limited data available from weather services, the most recent eight years have been significantly warmer than the historical average.)
The lows from February, March, and June were warmer than they’ve ever been, and our last freezing day was in the second week of January.
Rain-wise, this is the first year we’ve lived here in which all six of the first six months have seen two or more inches of rainfall. In fact, most years see at least one early month with less than one inch of rain. For the first time, our rain has been spread out evenly through the spring and early summer, instead of coming in bursts separated by long dry stretches. Our year-to-date total is 21.88 inches.
My prediction: we’ll have our second-rainiest year since living here (2015 being the rainiest year with 46.8 inches).
