September 2024 Weather Outlook: Above-Normal Rainfall and Warmer Temperatures Expected Across India

Warmer Temperatures Expected Alongside Rain

In addition to the increased rainfall, September 2024 is likely to bring warmer-than-average temperatures to most parts of India. Maximum temperatures are expected to remain above normal across much of the country. However, some regions, such as northwest India, the southern Peninsular area, and parts of east-central India, may experience temperatures that are closer to or slightly below normal.

Minimum temperatures are also expected to stay above normal in most regions, leading to warmer nights. Exceptions include isolated areas in northwest India, the Himalayan foothills, and southern Peninsular regions, where temperatures might stay within normal to below-normal ranges.

La Niña Conditions to Influence September Weather

Adding to the complexity of the weather forecast, La Niña conditions are expected to emerge toward the end of the monsoon season. Currently, the El Niño-Southern Oscillation (ENSO) is in a neutral phase over the equatorial Pacific, but the likelihood of La Niña developing is increasing.

At the same time, neutral Indian Ocean Dipole (IOD) conditions are present and are likely to continue through the remainder of the monsoon period. These oceanic patterns significantly impact atmospheric conditions and are expected to play a crucial role in shaping the weather across the Indian subcontinent as September progresses.
