Maharashtra is entering the October-December period with a large part of its water system already under stress, and the India Meteorological Department’s latest outlook suggests that the state may not receive the rainfall needed to ease that pressure. Below-normal post-monsoon rain, above-normal temperatures and declining soil moisture could connect drought conditions in rural districts with tighter irrigation, groundwater and urban water-management challenges.
The IMD has forecast below-normal rainfall across most of Maharashtra during October-December, with the strongest signal covering large parts of the state. It has also projected above-normal maximum and minimum temperatures across most of the state. The combination matters because rainfall deficiency is not the only measure of water stress: higher temperatures can increase evaporation and demand even when the immediate shortfall appears limited.
The forecast comes after a deficient monsoon and drought conditions affecting nearly 70% of Maharashtra, according to the report. The state is therefore not approaching the post-monsoon season with a full hydrological reset. Soil moisture, reservoir storage and groundwater recharge have to carry a larger share of the burden between the withdrawal of the southwest monsoon and the next substantial rainfall cycle.
For cities, this creates a risk that is often obscured by the way water systems are administered. Municipal supply is generally planned around reservoirs, treatment capacity, distribution networks and scheduled releases. But those systems are connected to the wider basin. Reduced rainfall affects catchments, reservoir recharge, groundwater conditions and the demand placed on irrigation sources. A city may continue receiving water for a period while the surrounding water system becomes progressively less resilient.
The IMD has cautioned that below-normal post-monsoon rainfall can affect soil moisture, water availability, irrigation requirements and agricultural productivity. It has also pointed to a higher likelihood of dry spells and reduced recharge of reservoirs and groundwater. These are not separate impacts. Lower soil moisture can increase irrigation dependence, while weaker groundwater and reservoir recharge can reduce the options available to farmers, households and local administrations later in the season.
The forecast also carries a heat signal. Solapur recorded a maximum temperature of 37.7°C, its highest October reading in 20 years, according to the report. The district’s all-time October record was 38.5°C in 1965. Sangli and Satara recorded temperatures above 35°C, while Kolhapur crossed 34°C. These readings do not by themselves establish a statewide heatwave, but they show how warm conditions are arriving alongside rainfall concerns in parts of southern and western Maharashtra.
The IMD official quoted in the report attributed the low prospects for good October rainfall to the influence of El Niño and the absence of favourable conditions for cyclogenesis, or the formation of cyclonic systems that can bring rain. Localised thunderstorms and showers remain possible, but the official said they are expected to be below normal in frequency. That distinction is important for water planning: scattered rainfall can produce short-lived relief without necessarily delivering the sustained, geographically widespread recharge that depleted catchments require.
Pune illustrates the uneven nature of the state’s rainfall position. The city received 64.1 mm of rain in September, its lowest September level since 2018, according to the report. The figure was slightly more than double the 30.3 mm recorded in September 2018, but below rainfall recorded in several other recent years. Shivajinagar recorded 128.5 mm in September 2014, 173.7 mm in 2015, 58.5 mm in 2016, 151.7 mm in 2017 and 287.7 mm in 2019.
This variation shows why annual or seasonal totals alone can be inadequate for understanding urban water risk. Pune’s September rainfall has varied sharply from year to year, and the timing of rain matters as much as the aggregate. Rain that arrives in intense, short episodes may create runoff, while longer gaps can increase soil-moisture loss and demand on stored water. The supplied data does not establish how Pune’s reservoirs or groundwater levels will respond to the October-December forecast, but it does show that the city is entering the period after a weak September.
The institutional challenge is that responsibility is divided. The IMD provides the forecast. State authorities manage drought response and water allocation. Irrigation agencies oversee reservoirs and canal systems, while municipal bodies manage treated water supply and distribution within cities. Groundwater conditions and agricultural demand add another layer. The effectiveness of the response therefore depends not only on the forecast itself but also on whether these institutions use it to coordinate storage, releases, irrigation requirements and urban supply planning.
The report points to increased dependence on irrigation systems and stored water for the rabi season if soil moisture declines further. That has consequences beyond agriculture. Irrigation demand can compete with other users for stored water, while lower groundwater recharge can intensify dependence on borewells and increase the pressure on already stressed aquifers. In urbanising regions, this pressure can affect peri-urban settlements and informal users who may not have the same reliability of piped supply as formally serviced neighbourhoods.
Higher minimum temperatures also complicate the water picture. Warmer nights can limit the period during which the land and built environment cool, while sustained warmth can increase water demand. The supplied material does not quantify the additional demand or establish a direct link between the forecast and municipal consumption. It does, however, identify a combined risk: less rainfall alongside above-normal maximum and minimum temperatures.
The most important evidence in the outlook is therefore not a single rainfall number. It is the interaction between a deficient starting position, a forecast for below-normal rain, elevated temperatures and weaker recharge prospects. Each factor can intensify the effects of the others. A rainfall deficit reduces available moisture; heat can accelerate its loss; and poor recharge narrows the options for the next phase of demand.
There is also a limit to what the forecast can establish. The IMD outlook describes probabilities and broad conditions, not the exact rainfall that every district or city will receive. Localised showers and thunderstorms remain possible. The report does not provide updated reservoir storage figures, groundwater measurements, municipal allocation plans or a district-wise assessment of agricultural losses. Those indicators will be necessary to determine how the forecast translates into actual water stress.
For Maharashtra’s cities, the immediate urban question is how far water planning is linked to the wider hydrological system. Reservoir operations, catchment rainfall, groundwater recharge, irrigation demand and municipal distribution are often discussed separately, although a prolonged dry and warm period can connect them quickly. Pune’s weak September rainfall and the state’s broader drought conditions make that connection especially relevant, even though the available evidence does not yet establish a specific municipal shortage.
The IMD outlook confirms a higher risk of continued moisture stress across Maharashtra during October-December. It also indicates that localised rain may not be enough to reverse the state’s broader deficit. The next signals to monitor are actual October rainfall, reservoir and groundwater recharge, soil-moisture conditions, irrigation demand and the response of state and municipal authorities as the rabi season progresses.
