Wind pattern and proximity to the water bodies like the Arabian Sea and the Bay of Bengal, does not allow the place to heat up much. The mean average maximum for the month of April is 32.9°C. In the last 10 years Cochin has not recorded more than 35°C but on Monday it broke the record as maximum temperature touched 35.4°C. Day temperature recorded on Wednesday was a shade better at 34.2°C.
By the end of April, temperatures start dropping as thunderstorms pick up and it starts pouring by the first week of June. The monsoon air masses enter Kerala by the first week of June and the average rainfall received in the month is 700 mm. The place receives good pre-monsoon showers as well with an average rain of 94.8 mm in April. This year till now, Cochin has received only 35.4 mm of rain, which accounts for the high temperatures. Inadequate rain has led to temperatures shooting up in the region.
However, according to the latest weather update by Skymet Meteorology Division in India, conditions are favourable for showers and just one spell could meet the deficit for the month. Confluence of air masses from both the water bodies could bring rain.
