Rainfall is a serious cause of attenuation for radio wave propagation at frequency bands above 10GHz. It is important to accurately predict the fading outage due to rain attenuation. Although the prediction method recommended by the ITU-R is suitable for temperate regions, it is not as suitable for tropical and equatorial regions. This is due mainly to the lack of rainfall and rain attenuation data in these regions. Rain attenuation studies have been conducted in the Universiti Teknologi Malaysia (UTM) and Universiti Sains Malaysia (USM). Rain data were collected in four locations: Kuala Lumpur, Skudai, Sri Iskandar and Bota. In this Letter, we present a study of the worst-month statistics, which is of importance to the designers of telecommunication systems. The collected data are used to derive the annual worst-month statistics and its relationship with the average annual distribution. This relationship was found to be close to that anticipated by the ITU-R.
