August-September rainfall likely to be ‘above normal' forecasts IMD, new initiative launched to provide real-time rainfall data for 7,200 blocks
NEW DELHI: Second half of the monsoon season (Aug-Sept) is most likely to receive 'above normal' rainfall over the country as a whole, barring a few regional exceptions, the IMD said on Thursday. Individually, Aug is expected to receive 'normal' rainfall whereas Sept may get 'above normal' rainfall, bringing the total quantitative rainfall to more than 106% of the long period average (LPA). The LPA of rainfall over the country as a whole during Aug-Sept, based on historical data from 1971 to 2020, is 422.8 mm. 'Many parts of northeast and adjoining areas of east India, some isolated regions of central India and south western parts of peninsular India may, however, get 'below normal' rainfall during Aug-Sept,' said IMD chief Mrutyunjay Mohapatra while referring to the regional exceptions. Releasing the outlook for rainfall during the second half of the southwest (summer) monsoon, Mohapatra also announced the launching of a new initiative, block-wise rainfall monitoring scheme (BRMS), that will provide 'real-time rainfall data' for 7,200 administrative blocks across the country. The new scheme will increase the spatial resolution of the forecast by tenfold, greatly enhancing the granularity and usefulness of rainfall data. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Your Finger Shape Says a Lot About Your Personality, Read Now Tips and Tricks Undo Earlier, only district-wise data was available. The key applications of BRMS include agricultural planning, disaster management, water resource management, model validation, policy making and more specific inputs for schemes like crop insurance scheme and MGNREGA. India received 'above normal' rainfall during the first half of the monsoon season (June-July). So far, the country recorded 6% more than normal cumulative rainfall during June 1 to July 31 period with central India recording the highest around 23% more than normal rainfall followed by northwest India at 21% above normal rainfall. On the other hand, east & northeast India recorded 22% deficit rainfall in the first two months of monsoon. The south peninsula also recorded a deficit of 2% during the period. Rainfall over east & northeast India was, in fact, seventh lowest since 1901 and fourth lowest since 2001. 'In northeast India, this is the fifth consecutive year of 'below normal' rainfall. Over the last 30 years, a declining trend in rainfall activity has been observed in the northeastern states,' said Mohapatra. Data show that 76 weather stations reported 'extremely heavy' rainfall events and 624 stations reported 'very heavy' rainfall events in July (most active month of the monsoon season) this year compared to 193 and 1,030 stations, respectively, in 2024. July this year has not seen widespread flooding in many parts like what the country witnessed last year. Except Himachal Pradesh that faced flash floods and landslides, no other states witnessed big rain-linked disasters in July. Good rainfall, so far, in most parts of the country also supported the ongoing Kharif (summer crops) sowing operations quite well, increasing the acreage by 4% till July 28 compared to the corresponding period last year. As far as temperature is concerned, the IMD said the monthly average maximum (day) temperatures are expected to remain "normal to below normal" in many regions in August. On the other hand, the monthly average minimum (night) temperatures are expected to be "normal to above normal" over most parts of the country in the month. "However, below normal minimum temperatures are likely over some parts of northwest India," it said.

Above-normal rains expected in Aug-Sep, likely to boost kharif sowing: IMD
India is likely to receive above-normal rainfall from August to September, further boosting kharif sowing and supporting the broader economy. "The rainfall averaged over the entire country from August to September is likely to be above normal (more than 106% of the long period average or LPA)," said Mrutyunjay Mohapatra, director general of meteorology at the India Meteorological Department (IMD), during a virtual press conference on Thursday. Based on historical data from 1971 to 2020, the LPA for the August to September period is 422.8 mm. According to IMD, during the second half of the monsoon season, normal to above-normal rainfall is most likely over most parts of the country. However, many parts of northeast and adjoining areas of east India, isolated regions of central India and southwestern parts of peninsular India may see below-normal rain, said IMD. Currently, neutral El Nino-Southern Oscillation (ENSO) conditions are prevailing over the equatorial Pacific region. The latest Monsoon Mission Climate Forecast System and other climate model forecasts indicate that the neutral ENSO conditions are likely to continue during the remaining part of the monsoon season. ENSO refers to changes in tropical Pacific sea surface temperatures and atmospheric pressure, which influence monsoon behaviour. In August,averagerainfall across the country is likely to be within the normal range (94% to 106% of the LPA). While normal to above normal rainfall is very likely over many parts of the country, central India, western parts of peninsular India, northeast India and some parts of east and northwest India are likely to receive below normal rains, according to IMD. India received 474.3 mm of rainfall from 1 June to 31 July, exceeding the normal average of 445.8 mm for the period. Most of northwest and Central India recorded above-normal rainfall during the period, while parts of the east and Northeast received below-normal precipitation. The South Peninsula also recorded slightly below-normal rainfall. Meanwhile, favourable monsoon conditions have already begun to reflect in agricultural activity, as kharif sowing has been completed in over 76% of the normal area. As of 27 July,total acreage under all kharif crops stood at 83 million hectares, up 4% from 80 million hectares a year earlier, according to agriculture ministry data. Paddy, the main food grain sown during the kharif season, has seen an over 13% surge in acreage to 24.5 million hectares. Pulses' acreage rose over 3.5% to 9.3 million hectares, while coarse cereals were planted across 16 million hectares, up 3.7% from 15.5 million hectares a year ago. A strong monsoon supports ahealthy crop output and also leads to low electricity consumption. That bodes well for agriculture and water resources. 'This anticipated rainfall forecast indicates restoration of surface water bodies—such as rivers, lakes and ponds—enhancing immediate availability for drinking, agriculture, and industrial needs. Moreover, widespread and timely monsoon showers aid in increasing groundwater levels, addressing the ongoing issue of declining water tables in multiple regions," said Poonam Sewak, VP programs and partnerships, Safe Water Network. The organization works with the private and public sectors to provideclean and safe drinking water, besides the rejuvenation of water bodies.

Kerala likely to get below-normal rain in August, September
Although Kerala received normal rainfall halfway through, a lean phase appears to be looming over the State during the remaining two months of the southwest monsoon season. The State received 1,190.5 mm of rain during the first two months of the season against the average of 1,301.7 from June 1 to July 31, the peak southwest monsoon in Kerala. The rainfall in the seasonal half is 9% short of normal rainfall. However, a deviation of up to plus or minus 19% is considered normal rainfall by the India Meteorological Department (IMD). The IMD warns of below-normal rainfall for Kerala in August and September, suggesting that Kerala is likely to end up with a deficit season this year. Couple of intense spells Speaking to The Hindu, Neetha K. Gopal, IMD Director, Thiruvananthapuram, said the southwest monsoon is likely to slip into a weak phase during the remaining half of the season. 'This doesn't mean that the rain will keep away. We expect a couple of intense spells, and the latest one to be around August 8 for two days, but cumulatively the overall rainfall will be in the below-normal category,' said Ms. Gopal. Traditionally, Kerala receives the highest average monthly rainfall in July (653.5 mm), followed by June (648.3 mm), August (445 mm), and September (271 mm). Though the monsoon trough now runs at mean sea level at its normal position, it will soon shift to the north of its position, closer to the Himalayan foothills, leading to scanty rainfall or a 'break in monsoon' in south India and heavy spells in northern India. Further, the prospects of forming monsoon systems over the Bay of Bengal with a position favourable to the Kerala and Konkan belt seem to be bleak for the time being. This, along with a poor monsoon surge from the Arabian Sea and weakened westerly wind flow, may reduce the rainfall activity over the State. The speciality of the healthy monsoon rain Kerala received so far was its almost even distribution without any major extreme spells. The appearance of the offshore trough along the west coast, one of the main features of the intense monsoon rainfalls in Kerala, was seen only a few days in the first half of the season. Instead, the cross-equatorial flow propelled the widespread and somewhat even distribution of the rain in Kerala. Similarly, most of the days, northwesterly winds were seen along the coast of Kerala, instead of westerlies. The westerly wind blowing into the State straightaway from the Arabian Sea towards the Western Ghats normally leads to heavy spells, while the change in direction of the wind will deprive the State of its orographic advantage, according to experts.

IMD predicts above-normal rainfall in India for August-September 2025
India is likely to receive above-normal rainfall during the second half of the monsoon season (August and September), the India Meteorological Department (IMD) said on Thursday. Most parts of the country, except the Northeast and adjoining areas of eastern India, are expected to record normal rainfall in August, said IMD Director General Mrutyunjay Mohapatra during an online press conference. Rainfall in September is likely to be above normal, he said. India received above-normal rainfall during the first half of the monsoon season (June and July), with some states, particularly Himachal Pradesh, experiencing flash floods. "Overall, above-normal rainfall (106 percent of the Long Period Average of 422.8 mm) is most likely over the country during the second half of the southwest monsoon season," Mohapatra said. "Geographically, normal to above-normal rainfall is most likely across most regions, except for many parts of the northeast and adjoining eastern India, isolated regions of central India and southwestern areas of the peninsular region, where below-normal rainfall is expected." Mohapatra said subdued rainfall is expected over the next two weeks; however, the conditions do not meet the criteria for a "break monsoon phase", which refers to a temporary lull in rainfall during the monsoon when the trough shifts toward the foothills of the Himalayas. The country received 474.3 mm of rainfall against a normal of 445.8 mm from June 1 to July 31, a surplus of six per cent. The country recorded 624 very heavy rainfall events and 76 extremely heavy rainfall events, the lowest figures in the last five years, the IMD chief said. "In Northeast India, this is the fifth consecutive year of below-normal rainfall. Over the last 30 years, a declining trend in rainfall activity has been observed in the northeastern states," he added. According to Mohapatra, good rainfall in July was due to favorable Madden-Julian Oscillation (MJO) conditions in the latter half of the month and the formation of six low-pressure systems spanning 28 days. Of these, four systems intensified into depressions. Among them, three formed over land and moved from Gangetic West Bengal/Northern Bay of Bengal to Rajasthan, triggering frequent heavy to very heavy rainfall and even extremely heavy rainfall on some days, the IMD said. ENSO-neutral conditions are currently prevailing and are expected to continue until October. Post-monsoon, weak La Nia conditions may develop, the IMD said. In May, the IMD forecasted that India would receive 106 percent of the long-period average rainfall of 87 cm during the JuneSeptember monsoon season. Rainfall ranging between 96 and 104 percent of this 50-year average is considered "normal". The monsoon plays a critical role in India's agriculture sector, which supports the livelihood of around 42 percent of the population and contributes 18.2 percent to the national GDP. It is also crucial for replenishing reservoirs used for drinking water and power generation.
