But this year the temperature has settled much higher than usual. For instance, Ahmedabad recorded 39.2°C as the day temperature on October 17, which is the highest in last ten years. Earlier record was also 39.2°C, observed on October 2, 2009.
This year many a times the day temperature in the first two weeks of October has crossed 38°C in most parts of the state, making it the hottest October in a decade.
The reason for rising temperature is subdued rain over Gujarat, Rajasthan and Sindh and Baluchistan province of Pakistan. Due to less rains dry and hot northwesterly winds begin to blow over Gujarat. As these winds come from dry regions of South Pakistan and Rajasthan, they increase the temperatures in Gujarat.
The 2015 Southwest Monsoon season had made a fantastic start as the countrywide rainfall by the end of June was surplus by 16%. But thereafter, the El-Nino effect took over and subdued rainfall activity was observed across the country in July and August. Rajasthan and Gujarat however observed good rains this Monsoon season.
