The Observatory recorded an average temperature of 26.24 degrees Celsius last month, making it the fifth-hottest October in the city on record. The average temperature last month was exceeded only by the 26.5 degrees last year, the 26.4 degrees that was recorded in both 1983 and 2006, and the 26.3 degrees in 1891. The Observatory forecasts cooler weather today after a cold front descended on the city from Guangdong province last night.
