May Used To Be Much Hotter In The US

On May 7, 1934 temperatures were over 100 degrees in Nebraska and Iowa. Algona, Iowa was 101 degrees, 27 degrees warmer than today’s forecast.

Prior to fifty years ago, 90 degree days were common on May 7 – with the five hottest years being 1934, 1916, 1952, 1962 and 1954. Since 1962, there hasn’t been a May 7 with more than 10% of the US over 90 degrees. The last two years (NASA’s hottest years ever) had less than 2% of stations over 90F.  2005 and 2013 were the two coolest May 7th’s on record.

For the entire month of May – 1934, 1911 and 1962 stand out as the three hottest years. The least hot May was in 2015, with 2016 close behind (NASA’s two hottest years ever.)

During May, 1934 more than two thirds of the US was in drought.

This year about 10% of the US is in drought, near or at a record low.

Climate experts says that global warming causes Spring heatwaves, but as with everything else in climate science – they are claiming the exact opposite of what the data shows.

      Several years ago we vacationed in Indiana, hitting places Holiday World and Schnitzel Bank.

      It was the mid-late summer, so we expected sunburns at the Holiday World swim park, but we instead got blue lips! The locals said they hadn’t had any summer at all, even their small gardens wouldn’t produce because of the lack of sun and abundance of cold!

    And as for precipitation?
    Average for my area: 5.1″ in May
    Per my own rain gauge we have had almost 10″ already this month.

    You forgot about the heat wave in Phoenix.

  4. AndrewB says:

    I guess all those old thermometers were reading hot.
    Looks to me that any good scientist would want to adjust those old temps down about 30-35 degrees.
    Y’all know we can’t keep any of that foolish data around!!!

    The April Palmer Drought Index showing northwest Connecticut in severe drought is complete bollocks, it’s been extremely wet here.

    • David in Ardmore says:

      Here in North Alabama, the long-term meteorological conditions say were in an extreme drought, but I can assure you everything here is fine, may be a little damp :)

        Hi. I know where Ardmore is ;). I’ve been there. I lived in Huntsville for a year. I’m living a bit south of you and locally this year is wetter than average and will stay that way if we don’t get a very dry summer and early autumn. We’ve gotten 35 inches so far this water year, which started very dry. If the rest of the water year is average, we will end at or above 55 inches.

    I live in one of those severe drought areas. Let me tell you, it isn’t that dry. We did have a couple of relatively dry years. This year is above average.

    Almost never will any year’s (water year) have an average amount of precipitation. The average annual here is 55 inches a year. I think the standard deviation is 5 inches, so 99% of the years will have between 40 and 70 inches of rain. I’ve seen a year with 70 inches, of which 20 inches fell that happened in June. That’s what the dark red on that map in Alabama means. Several years below 55 inches of precipitation. How many people around the world would love to have 40 or more inches of rain a year, pretty much every year, so long as it isn’t mostly in one month or during the normally drier months that correspond with harvest time? /rhetorical.
