Japan in Hot Water — Longest Heatwave on Record for Tokyo, Tens of Thousands Hospitalized
This morning, at 10:53 AM local time in Tokyo, the temperature was a sweltering 95.2 F (35.1 C) and climbing…
For six days running thermometers in that city have been above 95 degrees F (35 C). That’s the longest unbroken string of 95 degree + highs Japan’s capital has experienced since record-keeping began 140 years ago in 1875. In other words, parts of Japan are experiencing never-seen-before heat.
All told, recent days have seen fully 25 percent of Japan’s cities and towns hit temperatures above 95 F. It’s a heat that sinks bone deep. That gets into the blood. That makes it hard to keep going outdoors. A heat that causes injury and, sometimes, death. And over this summer more than 35,000 people have been hospitalized throughout Japan due to heat injury. Of those, more than 850 have remained hospitalized for three weeks or more. And from this grim tally 55 have now lost their lives.
Hot Ocean Waters Breed Heat Domes
The record hot air temperatures have come on due to a combination of factors. First, the ocean around Japan is abnormally warm. Recently, near-Japan sea surface temperatures have ranged from 2-5 degrees Celsius above established averages. That’s excessively hot water, especially when one considers that El Nino will typically draw the warm waters south and eastward. But this year is not at all typical with unusual-to-record heat now ranging much of the Pacific Ocean basin.
