Early Summer Heat Broils Northern Hemisphere

While the summer has started off relatively cool for the eastern two-thirds of the U.S. many other locations in the world have been broiling the past several weeks. Record or near-record heat has been observed in portions of Germany, Switzerland, Austria, Russia, India, Nepal, China, Japan, Korea, Libya, Chad, and Mexico. Here’s a brief summary of the highlights.

An intense heat wave has developed in portions of Europe the past few days. On June 9th Ihringen in Germany reached 37.9°C (100.2°F). This was close to the all-time German national heat record for the month of June (which was 38.2°C/100.8°F at Frankfurt on June 27, 1947). This time, Frankfurt reached a sweltering 35.0° C (95.0°F), unheard of so early in the summer. Severe storms have broken out along the heat boundary in Germany and France with six storm-related deaths reported so far in Germany. A thunderstorm brought a 150 kmh (93 mph) wind gust to Dusseldorf Airport causing it to close for several hours. In France hail up to 8 cm (3”) in diameter fell in Ile-de France, Paris.



Germans flocked to the beaches during the early summer heat wave this week that saw temperature reach 100°F. Photo Picture-Alliance/DPA.

In Switzerland the temperature reached 36.4°C (97.5°F) at Liestal (also on June 9th), well short of the Swiss June national record of 37.3°C (99.1°F) set at Grono on June 21, 2003, but impressive for this early in the month nevertheless. Temperatures in France topped off at 37.7°C (99.9°F) at Carpentras on June 10th. Climatologist Maximiliano Hererra noted that in northern Italy it reached 38.9°F (102.0°C) at least one (unspecified) location. In Austria, Schaerding hit 35.6°C (96.1°F) on June 10th with Vienna reaching 35.0°C (95.0°F) on the 9th. Elsewhere in Europe unusually hot weather for the early summer was experienced in the Lapland regions of Finland and Sweden last week with temperatures reaching 30°C (86°F) above the Arctic Circle for almost an entire week. In Russia, Moscow saw a daily record high of 28.6°C (83.5°F) on June 4th. This follows the unprecedented mid-May heat wave that struck Russia, Finland, and Estonia in mid-May (see my blog posted in May for details about this event.

Earlier I also blogged about the record heat wave in China, Japan, and Korea during late May and early June but some of the records mentioned therein were beaten more recently. Most impressive was that Sapporo, Hokkaido, Japan broke its June monthly record again on June 4th with a high of 33.7°C (92.7°F). Asahikawa, another major city in Hokkaido, hit 35.9°C (96.6°F) also on June 4th, smashing its previous June record of 34.6°C (94.3°F) set on June 24, 1905 and coming within just 0.1°C (0.2°F) of its all-time any month record of 36.0°C (96.8°F). Records at this site date back to 1889.

In China, a late report from a regional weather station, Nansha, in Yunnan Province claims a temperature of 44.5°C (112.1°F) was attained on May 29th. If accurate, this would be a new all-time national heat record for China for the month of May. It is somewhat verified by a 43.1°C (109.6°F) official temperature at nearby Yuangjiang the same week (on June 3) which was a new official all-time record for any month in Yunnan Province for a first-order site in the Chinese meteorological network.

Elsewhere in Asia, India has seen extreme heat for the past week. At New Delhi’s Palam Airport the temperature reached 47.8°C (118.0°F) on June 8th, the 2nd hottest temperature ever measured at that site. Agra hit a blistering 47.3° (117.1°F) on June 10th and 48.6°C (119.5°F) was reported from Ganganagar on June 8th, the warmest reading so far in the country. In Nepal the temperature peaked at 45.2°C (113.4°F) at Dipayal, just short of the all-time (any month) national record of 46.4°C (115.5°F) set at Dhanghadi on June 16, 1995.

Libya saw a temperature of 48.7°C (119.7°F) reached at the oasis of Jalu on June 3rd, just short of the site’s all-time record of 49.1°C (120.4°F) set back in 1961.

Chad saw a 47.0°C (116.6°F) reading at Faya Iargeau also on June 3rd which was just short of the all-time national record (for any month) of 47.6°C (117.7°F) set at the same site on June 22, 2010.

In Israel, Ben-Gurian Airport near Tel Aviv, reached 42.7°C (108.7°F) on June 4th, a daily record.

Mexico saw some amazing temperatures last week with a site in Sonora State called Moris reporting 51.5°C (124.7°F) on June 4th. This figure, however, is suspicious and not well verified by surrounding stations. A more believable 50.5°C (122.9°F) was registered at El Oregano on June 4th. This is just 1.5°C (2.7°F) short of Mexico’s all-time national heat record of 52.0°C (125.6°F) set at two sites in the Mexicali area in July 1995. The heat in northern Mexico brushed the U.S. Southwest during the first week of June. El Paso, Texas saw a string of four consecutive record-breaking days June 2-5 with a peak of 109°F (42.8°C) on June 3rd. This was the hottest temperature ever measured so early in the summer for the city.



El Paso, Texas got off to a hot start this June with four consecutive record-breaking days June 2-5. So far, the month is averaging 8.0°F above normal. Table from NWS-El Paso.

In Australia it is now late Fall, early winter so the summer days of extreme heat are long gone. However, May was one of the country’s warmest such with a number of late season heat records set. Below is a map pointing out some of the highlights:

Oh, thank your for the round-up of heat reports (somehow frighetning, to be true)! And reading all those numbers I'm really glad that temps in Germany and in my place stayed in the mid thirties (Celsius) and not forties or - forbid! - fifties! Tomorrow our temps will continually normalize *sigh of relief*.


Last day of heat anomalies for Germany - at least for a while, lol -, June 11 ... Source.

BTW, I'm not a member of facebook, but it's a great to follow news and pics of Europe's Severe Weather on this public page (click the pic):


Hail in Paris two days ago.
I'm curious how June's global temperature average will rank.
Quoting 2. BaltimoreBrian:

I'm predicting that summer 2014 will be one for the record books. Reasoning: We're near or at the peak of our current solar cycle, a strong El Nino is imminent over the next several months, and the CO2 level in the atmosphere has exceed 400 ppm: the highest since the Pliocene epoch. All the ingredients are in place for some extended-duration, sweltering temperatures this season.
Why can the temperature reach such hights in the Sonora State of Mexico in June like in Hermosillo or El Oregano? Does the orographical situation provoke calm wind patterns and thus the heat can build up or are there other heat generating patterns like the Foehn winds?


P.S.: speaking of further mexican records: according to Maximiliano Herrera's record temperature site, the worldwide heat record for the month of April was measured in Santa Rosa, Mexico. But I couldn't find the location since there are lot of Santa Rosas in Mexico. I was looking on the site of the Servicio Meteorologico Nacional.
I've been a big fan of your blogs for the last couple of years Chris. Keep the blogs and research on temperature records and worldwide weather extremes going!
Thank, Chris. Those are some amazing stats. Being humans and all, we tend to lazily think what we're feeling in our area is what everyone else is, and that's--obviously--not the case; a normal Florida summer doesn't mean it's normal everywhere else.

I've been reading some disturbing stories about the heat in some places, most notably parts of India, where heat-related civil unrest is building. Let's hope for a respite, and soon...
Mumbai, India set a new record maximum for month of June when temp reached 38 C on the 10th at the Santacruz weather station. Previous record was 37.1 C on 15th June, 1995

It Is near the area of Tamuin. Esta cerca de Tamuin. In April-May there are sporadic very strong downslope winds descending from the mountain range towards the plains/coast. Entre abril y mayo esporadicamente hay fuertes vientos catabaticos que bajan de la Cordillera hacia la costa. Also on 16 April 1998 nearby village of Aquismon recorded 50.0C the earliest 50C ever in the Hemisphere. Tambien el 16 de abril de 1998 el pueblo cercano de Aquismon habia alcanzado los 50C , los 50 grados mas tempraneros de todo el Hemisferio.
I can vouch for the German heat wave. Here in Stuttgart it reached 36.5C (98F) on Monday. I have been here for years and have never seen this in June. As usual, I heard about how high it can get in Florida, Arizona, etc. I grew up in Florida, and I know this, but everything was air conditioned.

Just remember, this is the land of no air conditioning. Most public buildings get very hot, like restaurants, banks, etc. My bedrooms at home were like saunas all night. Luckily, these hot spells do not last long, and it is actually much better today.
Most of the US currently above normal so far this month, and looks the eastern 1/2 of the country will be seeing its first heat wave soon so those numbers should be going up. With all the warmth so widespread + the developing El Nino, I bet this has a good shot at becoming the warmest June on record globally.

Thank you for the explanations! These are very impressive readings and what's also interesting to see is that the readings seem to be connected to El-Nino events. The people living there must be very tough to deal with such kind of weather.
Besides I found in the site of the Servicio Meteorológico the reading of 50C in Aquismon and I found a Santa Rosa in the district of Ciudad Valles (#00024076, operating since 1961) and the highest april reading is 48.5C april the 16th,1998.
Wow, people are overjoyed when temps in India fell below 45C/113F today!

Scattered rains bring joy to Delhi; no heatwave till June 18, says Met Dept
Last Updated: Friday, June 13, 2014, 00:52
New Delhi: After scattered rains and thunderstorms in several parts of the national capital on Thursday brought much needed relief to Delhiites, the MeT department predicted that the capital would be free from heatwave for a few more days.
"There won't be heat wave in Delhi now, people will be relieved from the heat till June", said M Duraisamy, Director, MET Department.
The capital was reeling under blistering heat coupled with long blackouts for over one week.
The MeT department said the city received 0.8 mm of rain till 5:30 in the evening. People came out of their offices and homes to enjoy the rain.
The maximum temperature today was recorded at 41.1 (106F) degrees Celsius, two notches above normal, and down from yesterday's 43.6 degrees. The maximum temperature between June 6 and June 10 was on a record breaking spree as it was 45 degrees and above.
The temperature came down by 4-5 degrees following the rains. The weatherman has predicted partly cloudy sky tomorrow with possibilities of light rain and thunderstorms in some areas.
Apart from the intense heat, people in the city are having a harrowing time with long blackouts ranging up to six hours as authorities are yet to restore many major power transmission lines damaged by the devastating storm on May 30.
Maximum temperature of 41.1 degrees was recorded at Safdarjung observatory, considered to be the official reading for the city. Elsewhere too, temperature dropped significantly and came below the 45 degrees mark.
At Palam, the day temperature was recorded at 43.6 degrees while at Ayanagar and Ridge area, the maximum temperature was recorded at 42.2 and 41.5 degrees respectively.
The minimum temperature in the city today was recorded at 30.5 degrees, three notches above the normal.
Humidity levels remained between 57 and 31 degrees Celsius during the day. The maximum temperature is expected to settle around 41 while minimum may remain as high as 31 degrees tomorrow.

Been there too... about 20 years ago. Can't imagine that temperature in that part of the world...
