A heat wave blanketing Iran has forced authorities to cut operating hours at various facilities Saturday and order all government and commercial institutions to shutter the following day as hospitals receive over 200 people for heatstroke treatment.

The temperature ranged from 37 degrees Celsius (98.6 degrees Fahrenheit) to 42 C (about 107 F) in the capital, Tehran, according to weather reports.

State-run IRNA news agency said banks, offices, and public institutions across the country would close on Sunday to protect people’s health and conserve energy, due to extreme temperatures and that only emergency services and medical agencies would be excluded.

Babak Yektaparast, Spokesman for the country’s emergency department told the semi-official Mehr news agency 225 people had to seek medical help for heatstroke, adding that some had to be hospitalized.

Mehr also cited Sadegh Ziaian, an official at the National Meteorological Organization, as saying Saturday that the temperature reached over 45 C (113 F) in 10 Iranian provinces, with the highest temperature of 49.7 C (about 121 F) recorded in the last 24 hours in Delgan, the southeastern city in Sistan and Baluchistan province which borders Pakistan and Afghanistan.

He added a drop in temperature was expected Monday, with the heat letting up a bit, but still, he warned that “this does not mean that the air will cool down.”

Authorities also cut working hours on Saturday in many provinces due to the sweltering heat, IRNA reported, adding that high temperatures, over 40 C (104 F), have been registered in Tehran since Friday. Iranian media also warned people to stay indoors until 5 pm local time.

Authorities also said electricity consumption reached record levels of 78,106 megawatts on Tuesday, as the scorching heat persisted and people tried to stay cool.

Nournews, close to Iran’s Supreme National Security Council, reported Wednesday that Iran’s temperature is rising at twice the pace of the global temperature which has increased by more than one degree compared to the long-term average. Meanwhile, Iran has become warmer by 2 degrees over the past 50 years, the agency said.

Last year, Iran ordered a two-day nationwide holiday due to increasing temperatures.

Bull sharks are lingering off Sydney's beaches for longer periods each year as oceans warm, researchers said Friday, predicting they may one day stay all year.

The predators are migratory, swimming north in winter when Sydney's long-term ocean temperatures dip below 19 degrees Celsius (66 degrees Fahrenheit) to bask in the balmier waters off Queensland.

A team of scientists looked at 15 years of acoustic tracking of 92 tagged migratory sharks in an area including Bondi Beach and Sydney Harbour.

Records show the sharks now spend an average of 15 days longer off Sydney's coast in summer than they did in 2009, said James Cook University researcher Nicolas Lubitz.

"If they're staying longer, it means that people and prey animals have a longer window of overlap with them."

Shark attacks are rare in ocean-loving Australia, and most serious bites are from three species: bull sharks, great whites, and tiger sharks, according to a national database.

There have been more than 1,200 shark incidents around Australia since 1791, of which over 250 resulted in death.

Researchers found an average warming of 0.57C in Bondi for the October-May period between 2006 and 2024, said the study published in the peer-reviewed journal Science of The Total Environment.

Over a longer period, remotely sensed summer sea-surface temperatures in the area rose an average 0.67C between 1982 and 2024, they said.

"If this trend persists, which it likely will, it just means that these animals are going to spend more and more time towards their seasonal distributional limit, which currently is southern and central New South Wales," Lubitz said.

"So it could be that a few decades from now, maybe bull sharks are present year-round in waters off Sydney," he added.

"While the chances of a shark bite, and shark bites in Australia in general, remain low, it just means that people have to be more aware of an increased window of bull shark presence in coastal waters off Sydney."

Climate change could also change breeding patterns, Lubitz said, with early evidence indicating juvenile sharks were appearing in rivers further south.

There was some evidence as well that summer habitats for great whites, which prefer colder waters, were decreasing in northern New South Wales and Queensland, he said.

Tagged sharks trigger an alarm when they swim within range of a network of receivers dotted around parts of the Australian coast, giving people real-time warnings on a mobile app of their presence at key locations.
