Delhi records high heat index as humidity levels rise
Delhi has recorded "feels like" temperatures reaching 53.5 degrees Celsius due to a combination of dry and humid air masses. While actual measurements remain in the low 40s, increased moisture from the Arabian Sea is significantly increasing the perceived heat.

Delhi has experienced significant spikes in perceived temperature as humidity levels rise across the capital. News18 reported that while actual temperature readings reached approximately 40 degrees Celsius, the "feels like" measurement peaked at 53.5 degrees Celsius.
According to News18, these conditions are driven by the interaction of two distinct air masses. Dry westerly winds from Pakistan have maintained high temperatures in the region, while southwesterly winds originating from the Arabian Sea have introduced significant moisture into the atmosphere. This combination of dry and humid air has increased humidity levels, which significantly impacts how residents experience the heat.
Livemint reported a "feels like" temperature of 48.4 degrees Celsius on Saturday. Their report noted that this figure was considerably higher than the actual maximum temperature recorded at that time, which was 41.3 degrees Celsius. The minimum temperature during this period was recorded at 30.8 degrees Celsius.
Forecasts for the capital indicate a shift in weather patterns starting soon. Livemint reports that rainfall is expected to begin on Monday, which may provide relief from the current high temperatures and humidity levels.
Why this matters
The discrepancy between actual temperature and "feels like" measurements highlights how humidity influences urban environments during seasonal transitions. These conditions demonstrate why heat index figures are a critical metric for public safety and local planning rather than relying solely on raw temperature data.
What's confirmed / what isn't
Both news outlets confirm that Delhi's perceived temperatures are significantly elevated due to high humidity. They report different specific figures for these measurements, with News18 reporting 53.5 degrees Celsius and Livemint reporting 48.4 degrees Celsius on Saturday.
Background
A "feels like" temperature, or heat index, is a measure that combines air temperature and relative humidity to determine how hot it feels to the human body. This metric is often used by meteorologists to provide a more accurate assessment of heat-related risks.
