On August 16, 2020 Death Valley reached a temperature of 54.4° Celsius, the hottest temperature ever recorded (with proper equipment and procedures) anywhere on Earth.
Not really all that surprising. The ocean has a very large mediating effect because the ocean temperature is highly resistant to temperature fluctuation (water has a very high heat capacity). Thus temperature near a coast is always more mild that the temperature several 10s of miles inland.
Hello to everyone from the front page! Thanks for taking the time to play my quiz today. If you want, feel free to check out some of my other quizzes, there are some good ones out there including a coldest version of this quiz. Have a great day!
It's amazing the effect the ocean has on weather. Florida, the southernmost mainland state, isn't actually that hot because of the weather. Yet, South Dakota, approximately the same Latitude as Southern Russia, is on this list!
The ocean is a very good regulator of temperature. Overall in Florida it is very hot but never to the point of the temperatures in this quiz - in fact, Colorado has more 100°+ days than Florida on average. And because of the high level of humidity, it seems significantly hotter than in places like Arizona, where the air is dry (this is because when it is humid it is more difficult for sweat to evaporate and cool you down) even if the weather in Florida is 10 or 15 degrees "cooler."
The source given is an absolute mess of data --- very few citations, very few dates, no sorting. One cannot verify the vast majority of their stats without going through considerable effort.
Yes, I agree. The original source was bad. The new source is better. In fact, I was so frustrated with the lack of good sources so I made my own website: Extreme Weather Watch.
It would be sort of cool (no pun intended) if the answer grid also displayed the year of that record. (If the info is available.) It would interesting to see how old or recent the record was.
Wow. This seems very bizarre. I am shocked North Carolina didn't make the list, as it has extremely hot summers that will melt your face off. Shocked to see South Dakota or Nebraska up here over NC. Perhaps it is simply because NC has the sweltering humid heat, that is so hot that it is hard to breathe, but doesn't register as high as the dry heat of places like Arizona.
Summers in the midwest are extremely humid. I've lived in Minnesota, Wisconsin, North Carolina, and New York. The worst heat I have experienced was Wisconsin and New York when it was humid. The heat in North Carolina feels hotter because the suns rays are more direct.
The high temperatures in the Dakotas, for instance, relate to the jet stream, which can dip down far south and bring hot air north in the middle of the country. As hot as it can get in the Carolinas, Georgia, and Florida, being on the coast and not being as affected by the jet stream help to keep the temperature more "mild".
The record high for North Carolina is 110 degrees and was set in 1983.
I think it's a combination of the topography and the elevation. What I mean by this is that it's super flat, but also super high up, so, I don't know if that has any effect. I'm probably wrong though.
South Dakota native here. For the record, the climate and geography of the Dakotas is quite varied, and I'd dispute Trombone's assertion that it's "super flat and super high up". The eastern part of the Dakotas are certainly pretty flat, but the western part is definitely not.
SD's high temp record was from the hilly northwest part of the state, but only ~2300 ft elevation. 2006 was a really hot and dry drought year.
I looked up Steele, ND which is where their record is from. ~1800 ft elevation, south central part of the state, pretty flat. Record set in 1936, so likely another drought year during the depression/dust bowl era.
I'll admit that I share your surprise that both of the Dakotas have higher record temps than Texas.
Working on my new site, Extreme Weather Watch, I've learned that the Dust Bowl was insane. All-time record high temperatures from the heat waves of 1934 and 1936 still stand in many places today, even places relatively far removed from the Great Plains such as New York City
The North Dakota record came in 1936, during the Dust Bowl, a very anomalous year with severe droughts that affected the mid-west and turned some of the normally green swaths of prairies and farmland into desert.
I live in a city in Los Angeles called Woodland Hills. The temperature in September 2020 reached 121 degrees F! Broke the record for hottest recorded temperature ever in Los Angeles
Surprised that the Dakotas made the list, for being so far north.
Oklahoma and even Kansas make sense to me, but I would have thought that Nebraska or Iowa got hotter temps that SD or ND. Must have been a freak weather pattern since it's the hottest recorded temps and not the hottest average temps.
The temperature swings in North Dakota are so wide that the state uses concrete for their highways rather than asphalt since the asphalt can't handle it. It makes a lot of sense that the Dakotas would have a higher high temperature than the humid southeast states.
Edit: This record was tied on July 9, 2021.
