Slightly off topic, but since you mentioned deserts, I noted that one of the most extreme places in USA - Death Valley California, had flash floods last week. https://www.iflscience.com/environment/a-giant-lake-has-appeared-in-the-middle-of-death-valley/

The article says Death Valley National Park holds the record for the hottest air temperature ever recorded on Earth 56.7C (134F) which occurred on July 10, 1913, at the aptly named Furnace Creek. It also holds the record for hottest ground temperature, a sizzling 93.9C (201F) on July 15, 1972, and the record for hottest month ever recorded with an average day and night temperature of 42.3C (108.1F) for July 2018 (which broke its own record set the previous July). It has a yearly average rainfall of 6 centimeters (2.36 inches) a year, making it one of the driest places on Earth too.

Visiting Furnace Creek will be on my bucket list if I ever feel the need to make one. Australia's heat records make us look like pikers. Although we still got the record for number of consec days 100 or over at Marble Bar. So that is something

A mild 44C on the day I visited there. I just love geography, geology, weather and climate so loved the whole area. rest of Family ( 2 teenage girls) unimpressed.

I confess to not being a heat lover. At least not humid weather (who is). But I am fascinated by Earth extremes like many are. In late Nov I am taking a trip to the Holy Land. The Dead Sea is on my intinerary as well as a town called Beit She'an in the Jordan Valley south of sea of Galilee. Interestingly enough there is a place not far from Beit She'an called Tirat Zvi which has recorded a recognised 54 in 1942. The Jordan Valley, like death Valley is below sea level. Crazy hot spots

I did get to Death Valley for a brief visit around 13 years ago, and it was a mild 41 deg C. It was still an extreme for me though because the day before we were in Yosemite national park and we had snow there.

I think that is around 250km distance between the two places. Incredible contrast. I wonder what the world record would be for hottest temp and coldest temp 250km from each other.

In a straight line Mount Whitney at 4419m (14,500ft)is not that far from Death Valley. Closer to Death Valle Telescope peak is 3000 odd metres.

We stayed at Bishop in a valley between ranges NE of Death Valley, so rain shadowed in every diraction. I think the place is dryer than most parts of inland Australia, yet is popualr for trout fishing

Certainly dry in the rain shadow of such high peaks. According to wikipedia, the lowest point in north America, Badwater Basin, averages 48mm per annum of rainfall. The evavporation rate is an 3800mm per annum and hence "This is the greatest evaporation potential in the United States, meaning that a 12 ft (3.8 m) lake could dry up in a single year." The Dead Sea by contrast has an evaporation rate of up to 1600mm per annum, whilst Lake Eyre can be up to 2000mm with a lot of water in it.

Not in the 50 class, but was Grafton's sneaky 39.4 a March record today? I say sneaky coz most eyes have been fixed on what Veronica and Trev have been up to.

Presume you mean specifically for Grafton itself? In that case yes. There's been quite a few March records across Australia this month I believe.

Yeh Grafton. I'm only going on the stats on Climate Data Online. The closed pool site has 39 in 2002. Of course, as can happen, there may be some non didged data out there that was hotter. I dunno

Today the warmest March day in Coffs Harbour since 1954. Temps from different sites. But still decent heat for this late in March in that area.

Speaking of heat I believe Rabbit Flat's 115 day run of temps exceeding 39c came to an end yesterday, Prior to that, the previous temp lower than 39c was on the 30th Nov last year !

Sounds like good place for cold frogs to avoid. Would that be some kind of record as far as you know? The longest stretch of 37.8 or over is still 160 days at Marble Bar in 1923/24 (a world record). There were 152 days of 39 or above. The longest straight stretch of those 152 was 90 days. If a pesky 38.3 hadn't punctuated the streak it would have been 127 days 39 or over

Blair can you confirm if Marble Bar still has that record for consecutive days over 37.8C or did Mecca end up beating the record? I recall you talking about them potentially breaking that record a few years ago?

In Jan 2009 a poster floated his opinion that mecca likely had beaten MB record. http://forum.weatherzone.com.au/ubbthrea...lace_#Post72997
Later in 2009 another poster claims to have found info that he believed resulted in Mecca dethroning Marble Bar. http://forum.weatherzone.com.au/ubbthreads.php/topics/91012/2
Blair Trewin seemed convinced that MB was no longer the record holder. Quote: "Could actually be quite a challenge to resolve things now because we don't know what the record is, we just know that Marble Bar doesn't hold it. There's a World Meteorological Organization working group on climate extremes which I'll be referring this to, and I think this would fall within their brief, but I'm not sure how easy it would be for them to find the relevant information." Unquote.
Has this ever been resolved? All I read is that MB is still on the throne.

Mecca certainly had a longer run than Marble Bar's. What we don't know is whether Marble Bar was ever a world record in the first place - the likely other candidates for such a record are in the Middle East and Africa, mostly in countries which have always used the metric system (but often have a less than stellar observations network) so wouldn't have paid much attention to a 100F threshold.

I believe the US record is 154 days at a site in Death Valley (where else?).

Are you saying we don't know if MB was a record streak because there may have been a longer one in places that have no records or have poor record keeping practices? If Mecca was longer why isn't it recorded as a record? Is it still waiting some kind of certification so to speak by the WMO?
