World record heat index recorded in Iran. Imagine this. 

If you thought this past week was hot in America, Iran might have set a new record for the hottest Heat Index ever recorded at 182°F! On Thursday July 31, 2025 at about 9:30 AM the air temperature at Qeshm Dayrestan Airport in Iran was 104°F with a dew point of 97°F creating a heat index of 182°F! This would break the previous record of 180°F set at the same location just last year on August 28.

I have not seen a verified dewpoint above 34C - most such readings are from the Persian Gulf region where the sea temperature is around 34C at this time of year.

Surprise there have been no posts about the heavy snowfall across Australia.. snowing even in Queensland. 

Some places have seen the heaviest snowfall in many years. Places seeing up to 40cm.

Since the 20th July the highest dewpoint recorded at Kuwait International Airport has been 16C. Most days at maximum temperature in mid afternoon, the temperature has been 48-50C and the dewpoint typically 10-12C. That yields a typical humidity of 10-15%. The same readings can be seen at Basra in Iraq and Ahwaz in Iran - all around that same area.

Apparently the PDO (Pacific Decadal Oscillation) is at a 170-year record negative value, of -4.0.

Anyone have any ideas if this could have implications for the coming winter?

I can see the logic to a certain extent. Given the high SSTs in the region, they may promote dominant HP cells further north than usual in the Pacific, which would promote deeper Arctic plunges though the central and eastern parts of the continent, but all to play for, as they say.
