The extreme heat across India is a sign that the monsoon may start early, but El Niño could eventually hinder monsoonal rain this summer.
New Delhi, India, is one location enduring extreme heat. Temperatures will continue to soar to around 42-44 C (108-112 F) through the end of this week.
The temperature reached 46 C (115 F) in Nawabshah, Pakistan, on Tuesday, the hottest temperature recorded in the region during the heat wave.
This magnitude of heat is occurring a bit earlier than normal but is not unheard of for this time of year. India's hottest weather often occurs before the onset frequent rains, called the monsoon.

The monsoon may be different this year because of the expected upcoming El Niño.
"The monsoon may start on time or even slightly early," stated AccuWeather.com Senior Meteorologist Jason Nicholls. "The current building heat may be a sign for an early start to occur."
"The rainfall during the monsoon season may be less than normal and more sporadic, especially in the north," continued Nicholls. "During the drought that occurred in the summer of 2009, the monsoon started on time and ended late, but rainfall during the season was hindered by the onset of El Niño that summer which again may be the case this summer."
"I anticipate El Niño to kick in and create problems for the monsoon this July and August."
In a normal year, the monsoon begins at end of May in southeast India then slowly builds northward, reaching New Delhi during the second half of June.
