Indians weather the heat with smartwatches and cool roofs
It is a little past 10am and the heat is already blazing on the outskirts of the Western
Indian city of Ahmedabad.

Sapnaben Chunara, a 30-year-old mother of three, has just finished her morning chores. She seeks respite from the heat in the shade of a neem tree, a species that can withstand high temperatures and drought.
Chunara spends most of the day outdoors in Vanzara Vas, a low-income neighbourhood of about 800 families, because her tin-roofed house is even hotter. Indoor temperatures can be even higher, especially when outside they climb above 40 degrees Celsius (104 degrees Fahrenheit).
That was once rare but now happens regularly. And this year, high heat started three weeks earlier than in previous years, touching 43 degrees in early April.
'Sometimes it gets so hot, I can't think straight,' said Chunara, sporting a black smartwatch that contrasts sharply with her colourful bangles and sari.

Chunara is one of 204 residents of Vanzara Vas given the smartwatches for a year-long study to find out how heat affects vulnerable communities around the world.

Heat warnings taken to heart as hajj reaches peak
Heat warnings taken to heart as hajj reaches peak Muslim pilgrims pray at dawn on Saudi Arabia's Mount Arafat. Photo: AFP Muslim worshippers prayed on Mount Arafat during the high point of the hajj pilgrimage as authorities urged them to avoid the hottest hours of the day after tragedy struck last year. Thousands of white-robed pilgrims recited Koranic verses from dawn on the 70-metre rocky rise near Mecca on Thursday, where the Prophet Mohammed is believed to have given his last sermon. But numbers thinned by midday following official warnings for pilgrims to stay inside between 10 am and 4 pm. Saudi authorities have taken steps to reduce the risk from heat at the hajj, which has drawn more than 1.6 million pilgrims to one of the world's hottest regions, according to fresh figures published on Thursday. Barring a few years of Covid restrictions, this hajj season has recorded the lowest number of pilgrims in over three decades. The dip comes after 1,301 people died in temperatures that hit 51.8 degrees Celsius last year – most of them illegal pilgrims, according to Saudi authorities, who implemented stringent measures to reduce their numbers this season. Unregistered, non-fee-paying pilgrims lack access to the full amenities offered during the hajj, including air-conditioned tents, making them particularly vulnerable to heat-related health risks. On Thursday, ice packs were handed to people walking towards Mount Arafat, with some placing the small bags on their heads. With temperatures reaching 42 degrees, officials ushered people away if they spent too long in one place near the bouldered hill, which had fans spraying mist and cool air at its foot. (AFP)

UAE tops 50C in highest May temperature on record
UAE tops 50C in highest May temperature on record The record high temperature of 50.4°C beat the 50.2°C seen in 2009. Photo: AFP The United Arab Emirates registered a sizzling 50.4 degrees Celsius on Friday, the highest on record for May, following weeks of sweltering temperatures in the desert nation acutely vulnerable to climate change. Worshippers at Friday prayers reported feeling faint and some residents appeared unsteady on their feet, even in a country that is accustomed to extreme temperatures. The highest temperature was recorded in an area of Abu Dhabi, the capital of the oil-rich Gulf state that lies in one of the world's hottest regions. "The weather was extremely hot today, unbearably so," said one 26-year-old Abu Dhabi resident, who said he arrived at the mosque late and had to pray outside. "I was drenched in sweat by the end of the prayers," he said, preferring not to give his name, adding that he felt like he was "about to faint." The high temperature of 50.4°C (122.7 Fahrenheit) is the hottest in May since records began in 2003, outstripping the 50.2°C seen in 2009, said the National Centre of Meteorology. The UAE, one of the world's biggest oil exporters and host of the Cop28 climate talks in 2023, has just emerged from a record-breaking April with an average daily high of 42.6 degrees Celsius. (AFP)
