From ToI
1892 year, a year which will be remembered as very dry and hot winters, very dry and hot summers but good monsoon especially in last 2 months of monsoon. Temperature in all winter and summer months were excessively above normal just opposite of its last year 1891 when temperatures were excessively below normal in its winter and summer months. Below image shown are temperature data of various parts of India of January and Feb month (All data is in Fahrenheit. To convert it into Celsius just divide it by 1.8)
Below attached image shows temperature data of March,April,May month of various parts of India. You can see how high the temperature were in 1st 5 months of the year especially in upper and western parts of India. (All data in Fahrenheit to convert it into Celsius just divide it by 1.8)
Temperature in March month itself become so high that it already touched to 43-46c range in most parts of N, W and central parts of India shattering many past records.

In last week of April a small cyclonic storm of considerable intensity formed in Arabian sea and has made landfall over kathiawar (Sauarshtra) just to the west of Mandvi on May 1. The average velocity of wind between 10 am to 1:30 pm in Bhuj almost exceeded 100 miles per hour (161 km/h) causing the massive damage. In whole of Kutch 38 persons were killed while 141 people were wounded. About 98,000 houses were damaged, 30 boats were destroyed. About 1,26,000 trees were uprooted and 5,00,000 trees were much injured.

Jeypore(Rajputana) 45c on 21st

In June month monsoon remained very poor especially the Arabian sea branch and so temperature remained above normal in most parts of upper and western India
(Data given here is in Fahrenheit. To convert it into Celsius just divide it by 1.8.) So straight 6th month temperature remained above normal for upper and western India. Except deccan plateau and Madras whole India received scanty rain
It seems summers is in no mood to leave India as straight 7th month India was under the grip of deadly heat shattering many past records due to massive failure of monsoon.
Dera Ismail khan 49c (10c above normal) shattering 47.5c record of July 1888

Jacodabad 47c. Record not broken (48.6c in July 1878)
Agra 46c(12.5c above normal) shattering 44c record of July 1868
From the last week of July finally monsoon currents became strong and gave bountiful rain in almost all parts of India which continued even in August month
Rainfall was largely in excess in all parts of India in August month as can be seen in above image giving much relief from prolonged heat waves. Many flood events occurred in Punjab and Sindh in August month. Nothing remarkable happened in September and October month.
North East monsoon which gives rainfall to South east coast in November and December month completely failed.
As you can see whole SE coast of India were largely in deficit. Even in December month north east monsoon failed considerably.
