A heatwave is period of excessively hot weather that is usually defined as "a period of more than 5 consecutive days where the daily maximum temperature exceeds the average maximum temperature by 5°C or more."
Extreme and abnormal weather phenomenon is becoming very common-usually attributed to the environmental damage.
This year is no different.
Severe heat killed more than 1,100 people in India during the month of May alone.
India recorded its highest maximum temperature of 117°F (47°C) in the state of Odisha.
Shocking as the numbers may be, this isn’t the worst heatwave to hit our planet. Here are some of the worst from around the world in recent years.
In 2014, temperatures in Australia reached up to 111°F (44.2°C). The town of Narrabri located northwest of Sydney saw temperatures as high as 118°F (47.7°C) on Jan. 3. The extreme temperatures caused dozens of bushfires across the country. There were reports of 100,000 bats dropping dead in Queensland and ranchers were forced to slaughter their cattle.

Think of Russia and snow and temperatures as low as -22°F (-30°C) come to mind. But in 2010, the country suffered the worst heatwave in decades giving rise to wild fires and severe drought – the likes of which had not been seen since decades. The temperature went as high as 128.3°F (53.5°C), causing 11,000 deaths in Moscow alone between July and August.
"Our ancestors haven't observed or registered a heat like that within 1,000 years. This phenomenon is absolutely unique," said Alexander Frolov, Head of Russia's weather service.
In 2003, a record-breaking heat wave swept across Europe, killing between 20,000 and 35,000 people, mainly in France. No one was ready to deal with such a large number of deaths and temporary mortuaries were set up in refrigeration lorries. Dr. David King, a scientific advisor to the U.K. government, called it the biggest "the biggest natural disaster in Europe on record."
For seven days temperatures topped 104°F (40°C) in northern France.
The River Danube in Serbia fell to its lowest level in 100 years, revealing bombs and tanks submerged since World War II.
In Portugal 215,000 hectares area of forest were destroyed.
Extreme snow and glacier-melt in the European Alps led to increased rock and ice falls in the mountains.
