The state of Kerala is experiencing a clear change in weather with unusual early signs of typical monsoon activity. The amount of cloud cover has increased significantly, as has the moisture content of the atmosphere, and there are now sporadic occurrences of pre-monsoon showers, suggesting that the transition from the dry season to wet season (monsoon) may happen much earlier than has been expected.
What’s Changing in Kerala’s Weather?
The weather in the state of Kerala is steadily changing within its atmospheric conditions. Generally, monsoon season begins in early June; however, due to moisture being transported from the Arabian Sea and slow-moving areas of weather, it appears that we may see an early premonsoon as well.
Currently, the state can expect:
– Several districts to have intermittent rains
– increased cloud cover in the afternoons
– thunderstorms with strong winds
– lower daytime temperatures because of rain
Why Is This Happening Early?
The early onset-like conditions are primarily linked to:
1. Build-up of moisture over the Arabian Sea
Air has been made uncharacteristically humid with large amounts of moisture entering into the atmosphere from water evaporating off the Arabian Sea (where the temperature of the ocean has increased dramatically).
2. Atmospheric instability
The temperature differential between the land surface and the Sea Surface is causing atmospheric instabilities. These instabilities are resulting in thunderstorms and precipitation.
3. Pre-monsoon circulation pattern
Circulation patterns indicating the southwest monsoon system’s establishment are leading to pre-monsoon conditions earlier than usual.
Impact on Daily Life
Rainfall is changing how people live and work in Kerala:
Weather Relief
Temperatures are lower because of the rain, and this will provide some relief from the heat wave that was building up for some time now.
Traffic Disruption
During short bursts of heavy rain, traffic can become really slow due to all the water on the road, particularly in cities like Kochi and Thiruvananthapuram.
Agricultural Advantage
Early rains can help farmers get their soil properly prepped with enough moisture before the actual monsoon season arrives.
What to Expect in the Coming Days
As seen in the previous forecast graphic, they expect to see sunshine, clouds and rain in Kerala over the next 7 days. Rainfall may be intermittent, but when it does it will likely come down in bursts towards the end of the day.
Is This the Actual Monsoon Arrival?
No, not yet. The southwest monsoon does not actually start until the Meteorological Department has determined that certain local and global weather conditions exist. Rainfall in Kerala now, is just a type of “Pre-Monsoon” rainfall that usually occurs about a month or two (… and sometimes longer) before the actual arrival of monsoon season.
Final Thoughts
The “Early Weather Change” in Kerala shows how weather patterns are getting more dynamic with time. It relieves people from excessive heat and will support many farmers, but people must continue to be ready for sudden and unexpected weather changes, wherever they may live.
FAQs
1. Has the monsoon officially arrived in Kerala?
No, these are pre-monsoon conditions. The official monsoon onset is usually declared in early June.
2. Why is Kerala getting rain early this year?
Increased moisture from the Arabian Sea and atmospheric instability are triggering early rainfall.
3. Will the rain continue throughout the week?
Rain is expected in intermittent spells, mainly during afternoons or evenings.
4. Is this good for agriculture?
Yes, early showers help improve soil moisture and prepare for the main monsoon season.
