Jharkhand’s monsoon activity is showing signs of gradually weakening, but the rainy spell has not ended completely. Intermittent rain and cloudy conditions continue in several parts of the state, including the capital Ranchi. According to the latest weather forecast, Ranchi may receive light to moderate rain or thundershowers at different times through September 17, while the complete withdrawal of the monsoon from Jharkhand is expected around October.
Weather conditions in Ranchi have remained changeable over the past few days. The sky has at times remained heavily overcast, followed by brief spells of rain before conditions return to normal.
According to the city-wise forecast, Ranchi may receive one or two spells of rain or thundershowers on September 12. Cloudy conditions and the possibility of rain or thunderstorms are also expected on September 13 and 14. One or two spells of rain or thundershowers may continue between September 15 and 17.
A significant rise in temperature is not expected in Ranchi during the next few days. The forecast indicates that the maximum temperature may remain around 28 to 30 degrees Celsius, while the minimum temperature is likely to stay around 22 to 23 degrees.
Rain and cloud cover may cause fluctuations in daytime temperatures, with a combination of humidity and cooler conditions.
Monsoon rainfall during September remains important for agriculture and water sources in Jharkhand. Rainfall during this period directly affects paddy and several other crops in rural areas.
However, excessive rainfall can also lead to waterlogging in fields, flooding in low-lying areas and disruption of movement on rural roads. The amount and distribution of rainfall across different areas will therefore remain important in the coming days.
The subdivision-wise warning issued by the Meteorological Centre, Ranchi, on September 10 forecast heavy rain along with thunderstorms and lightning in Jharkhand on September 10 and 11. A thunderstorm warning was also issued for September 12, while no widespread warning was issued for the state from September 13 to 16.
This indicates that rainfall activity is not expected to end completely, although the spell of heavy rain may weaken.
The latest weather report for Ranchi also forecast cloudy conditions and one or two spells of rain or thundershowers on September 11 and 12. The possibility of clouds and rain remains on September 13 and 14.
One or two spells of rain or thundershowers may occur on September 15 and 16. Light to moderate rain is expected to remain possible in Ranchi through September 17.
According to weather experts, the withdrawal of the monsoon does not occur suddenly on a single day. Several weather indicators are considered, including a reduction in atmospheric moisture, a sustained decline in rainfall activity and changes in wind patterns.
According to the India Meteorological Department, important indicators for declaring monsoon withdrawal include a sustained reduction in rainfall activity over an area, the establishment of an anti-cyclonic circulation at lower levels and a sufficient reduction in atmospheric moisture.
The initial estimate regarding the date of monsoon withdrawal may change. If moisture and rainfall conditions return after rainfall activity declines for several days in an area, the withdrawal of the monsoon may be delayed.
Therefore, the possibility of the monsoon withdrawing around October should currently be viewed as a weather trend.
The monsoon in Jharkhand generally begins to weaken gradually after September, with the withdrawal process accelerating during October. Weather records from previous years have also shown the monsoon withdrawing from the state around the beginning or middle of October.
A weather update in 2024 had also estimated that the withdrawal of the monsoon from Jharkhand would begin around October 12.
If the current weather trend continues this year, rainfall activity may gradually decline during the second half of September. However, this does not mean that rainfall will stop completely across the state after September.
Even as the monsoon weakens, rainfall may continue in some areas because of local weather systems, systems developing over the Bay of Bengal and local convection.
Residents of Ranchi are currently experiencing intermittent rainfall. Conditions have frequently included cloudy skies from the morning, rain during the afternoon or evening and clearing weather after some time.
Rain may also result in water accumulation on roads in some parts of the city and affect traffic. Vehicle drivers may face reduced visibility and slippery roads during rainfall.
The risk of lightning also remains during rain and thunderstorms. In recent days, the weather department has issued warnings regarding lightning and b winds in several parts of Jharkhand.
People are advised to avoid standing in open fields, agricultural areas, under trees or near electricity poles during such conditions. Farmers and people living in rural areas need to closely monitor weather warnings.
The weather in the coming days will remain important for farmers across the state. Rain can be useful for paddy crops, but excessive rainfall can also cause damage through waterlogging in fields.
In areas where water has already accumulated, continued rainfall could worsen the situation. In regions that have received less rainfall, light to moderate rain may benefit crops.
As monsoon activity weakens, the effect of sunshine during the day may gradually increase and maximum temperatures may also rise. Cloud cover and rainfall are currently keeping temperatures in Ranchi under control, but temperatures may rise normally as rainfall activity decreases.
Changes in atmospheric moisture could also affect humidity levels.
After the monsoon withdraws from Jharkhand, another change in weather conditions is generally observed. As rainfall decreases, morning and night temperatures gradually begin to fall.
However, the heat does not completely disappear by the end of September or the beginning of October. Daytime sunshine may feel intense, while nights may become relatively more pleasant. After mid-October, cooler conditions gradually begin to increase.
Residents of Ranchi and other parts of Jharkhand may have to wait for some more time before rainfall ends completely. Light to moderate rain is expected to continue in Ranchi through September 17, while other parts of the state may also receive rain depending on local weather conditions.
Rainfall activity is expected to gradually decline thereafter, but the official withdrawal of the monsoon will be declared only on the basis of the criteria set by the weather department.
Overall, the monsoon has not completely withdrawn from Jharkhand. Clouds and rainfall are expected to affect Ranchi over the next several days, while signs indicate that monsoon activity may weaken during the second half of September. With the possibility of monsoon withdrawal around October, residents will need to monitor local warnings related to rain, thunderstorms and lightning. Farmers, vehicle drivers and people living in low-lying areas will need to take particular care as weather conditions change.
