How Hot Was the Hottest Summer in Las Vegas History?

I keep seeing that Las Vegas just got through its hottest summer in history. Lots of records fell. Can you please give us a rundown of those records to show us exactly how hot it was?

We've been keeping track of the records all summer, so we're happy to compile them all in one place. Especially now that it's nice and cool hereabouts.

It wasn't a record, but our first 100-degree day was on May 17 compared to the average first date, May 24. The earliest Las Vegas ever hit 100 was on May 1, 1947.

Beyond May 17, Las Vegas temperatures surpassed 100 degrees on 112 days, beating the previous record of 100, also set in 1947. Between 1991 and 2020, the average number was 78 days.

In addition, this summer, 36 days went over 110 degrees. The previous record, again set in 1947, was 29 days. The average is nine.

The meteorological summer, the three-month period that begins on June 1 and ends on August 31, was the hottest on record with an average high temperature of 107.6 degrees. The normal average is 105.6.

On August 23, Las Vegas had experienced 64 consecutive days with temperatures 100 degrees and above. That day, the official high registered at the airport was 96, ending the triple-digit streak that started on June 19. The previous record of 66 days was set in 1944 and remained intact after 80 years. (Better luck next year!)

Finally, last month was the hottest October on record. The average temperature was 76.5 degrees, beating the previous record set in 2003 at 75.3 degrees. October's average temperature is 70.4. That record was helped along between October 2 and 6, when a late-season heat wave broke the high-temperature records five days in a row. And October 6 was the latest day in the year ever to hit 100. Once again, the prior record was set in 1947 on Oct. 4. The average last date for triple-digit temperatures is Sept. 18.

Early July heatwave

I know that the whole summer in Vegas can be considered a heatwave, but no mention specifically of early July this year?  It hit 120!?!?  Wasn’t that the ALL TIME high!  It made the week of 115+ degree days around it seem refreshing.

Las Vegas was a Sea

And once upon a long time ago, Las Vegas along with much of the southwest desert was a shallow sea. True!

Global drying anyone?

This little blip in temps in Las Vegas temps is statistically nothing vs what our world has gone through over eons of time. From MIT:

https://climate.mit.edu/ask-mit/has-there-been-climate-change

"The Earth’s climate and atmosphere have changed drastically over the last 4.5 billion years. Today’s global average temperature is around 59°F, but scientists estimate it has been as low as 10°F (during “snowball Earth” events) and as high as 95°F or above2 (so hot the Arctic North resembled today’s tropics). The atmosphere has changed too: Earth used to have very little oxygen, until the first cyanobacteria (or “blue-green algae”) showed up and started producing it. Today, oxygen is the second-most common element in the atmosphere."

1940's Global Warming

Thanks to Democrat Presidents Truman & FDR in the 40's we got global warming under control. Then the Eisenhower and other Republicans came in.

politics?

I thought Anthony said politics was off limits and such posts would be deleted, ie "burned"????

Re: Kookmeyer

They came in, where its air-conditioned, to escape the heat. Right?

My thought exactly.  Tired of hearing all the p&m about politics!

Eileen

Really gets old, yes! 

Anthony several times posted here saying he was going to delete any further political responses, made a definitive response not so long ago. His platform in the end but given there's no follow up by him or LVA staff to deleting the R and D mentions like he said he would once again, it appears political discussion is allowed and a-ok.

Sigh.

People running boards or forums where comments can be posted have two choices.  Review every post before it goes up and listen to people complain how long it takes for their comments to appear.  Or let the comments go through immediately and edit/delete inappropriate material later when someone gets a chance to review them.  Having 24/7 coverage is obviously not practical for a forum like this with a relatively small audience.  So be careful what you wish for (option one) because you may get it.  Frankly I find all the complaining and bickering more annoying and just ignore it.

Sometimes you gotta let them speak and be seen so everyone can see how dumb they are and then move on.
