how hot?

This weekend, the San Francisco Bay Area is having an historic heat wave. In the City, temperatures reached 106°F, while out here in Concord, we have seen 116°. On September 2, Concord was hotter than Bangkok and Death Valley! Since Weather Underground has great data, I thought I’d take a look at the trend.

First, here at our house: We have a weather station in the backyard that reports data to Weather Underground. It tells us the following about the period from Memorial Day through today this year:

  • 96° – the average maximum temperature
  • 77° – the average of the 24-hour mean temperatures
  • 56 – the number days where the maximum temperature exceeded 95°
  • 33 – the number days where the maximum temperature exceeded 100°
  • 24 – the number of days where the maximum temperature exceeded 105°

Yes, it’s been hot, but has this year been hotter than others? I looked at the historical data for Buchanan Airfield (KCCR) for the past 30 years and I came up with a few interesting charts. (Click on these to see a bigger version.) Traditionally, summer runs from Memorial Day through Labor Day: that’s the period covered in these graphs.

The “mean temperature”, which is the overall temperature in a day, was at an all-time high this year. From 1988-2014, the range was 69° to 72°. 2017 has been higher than that: the average mean temperature has been 75°

one tough chicken

 

This is Madison, our Blue Laced Red Wyandotte. She is a champ when it comes to laying, giving us around 300 eggs over the past 12 months, rarely taking a day off. (The day off happens because her laying cycle is more than 24 hours, so eventually she runs up against the night. Chickens don’t lay at night.) This week, she proved admirable in another way.
