Dengue incidence has grown dramatically around the world in recent years. It is transmitted by Aedes mosquitoes. Many climatic factors contributed to the vector densities such as temperature, relative humidity, rainfall and winds. This study is to determine the trend of climatic factor associated with dengue cases. The analysis was performed by using Pearson’s Correlation and Mann-Kendall trend analysis from 2012 to 2016. The Pearson’s Correlation showed that dengue cases in Kuala Lumpur were signifi cantly correlated with temperature, relative humidity and rainfall (p < 0.05). Mann-Kendall trend analysis showed that in both 2012 and 2014, the rise in dengue cases were aff ected by the increases in temperature and wind speed, while the relative humidity and rainfall aff ect the dengue with decreasing pattern. As the conclusion, climate factors such as temperature, relative humidity and rainfall contributed to 4.4% of the dengue cases in Kuala Lumpur from year 2012-2016.
