The pan evaporation rate is an important measurement that can be used to derive other meteorological parameter such as the evapotranspiration and drought indices. Learning the trend of pan evaporation rate is useful to pro-ject the possible trends of other important parameters. In this study, trend analysis of pan evaporation rate was conducted at four stations, namely at Station 96471 (Kota Kinabalu), Station 96477 (Kudat), Station 96481 (Ta-wau) and at Station 96491 (Sandakan), to evaluate the effect of climate change on the pattern of pan evaporation rate from January 1985 to Decem-ber 2019. The Mann Kendall (MK) test (assisted by the Sen’s slope estima-tor) and the Holt’s Linear Trend Method (HLTM) were used to perform the trend analysis. It was found that the pan evaporation rate was sensitive to climatic conditions such as drought and rainfall. Generally, the trend report-ed in the MK test and Sen’s Slope estimator tallied with that of the HLTM. However, in some instances, the HLTM was less sensitive as it could not de-tect the trends that were alerted by the MK test and Sen’s slope estimator. Overall, the findings of this study was in agreement with other researchers conducted in similar regions, and therefore could be a useful tool in the deci-sion making process.
