Watching the Almanac

Watching the almanac: Starting on January 7th, Birmingham slid into its coldest period of the year according to climate records. From January 7th through January 20th, Birmingham highs and lows average 52F and 32F respectively. But something happens on January 21st. That average high slips back up to 53F. By the end of the month, our daytime highs will be averaging 55 degrees, and overnight lows still just above freezing at 33 degrees.

Those average highs will jump six degrees in February to 62F and eight degrees in March to 70F by the end of the month. April and May will see seven degree jumps. By the end of May, the average high will be 84F. Those average highs will continue to rise until the period between July 15th through August 15th, when they will peak at 91F.

Something else has been afoot lately. Starting on January 15th (really around January 8th, probably,) our sunrise times started to get earlier each morning. Interestingly enough, our sunset times have been getting later since early December. That explanation is beyond the scope of this column. Suffice it to say, that the days are getting longer, and the temperatures will continue to get warmer.
