Why did Delhi's 'feels like' temperature reach 53.5°C?

Delhi remained under intense heat on Tuesday as the 'feels like' temperature touched 53.5°C, although actual temperatures stayed around 40–41°C. Experts said dry winds from Pakistan and moisture-laden winds from the Arabian Sea increased humidity and discomfort. The interaction between these dry and moist air masses leads to cloud formation, but there isn't enough moisture for widespread rainfall.
