On average, Singapore experiences 168 thunderstorm days per year. This refers to the number of days in which thunder is heard over Singapore, and gives an indication of lightning activity (as thunderstorms are associated with lightning). The monthly distribution of mean thunderstorm days as recorded at the climate station at Changi is shown below. More thunderstorm days are observed during the Inter-Monsoon months of April and May and October and November. The months of January and February in the later phase of the Northeast monsoon experience the least number of thunderstorm days."
