The new generation of structures which is flexible, low in damping and light in weight generally exhibits an increased susceptibility to the action of wind. The performance of structures subjected to the action of wind will be adequate during their anticipated life from the standpoint of both structural safety and serviceability.  The aim of this study is to conduct initial wind characteristic study and spatial wind mapping for coastal and delta regions of Myanmar by using geographic information system (GIS). Wind data measured at 10 m height for twenty-six selected stations which are located in Rakhine State, Ayeyarwady Region, Yangon Region, Bago Region, Mon State and Tanintharyi Region are obtained from Department of Metrology and Hydrology, Myanmar. In this study, power law is used to obtain wind profile for different heights above ground level. Weibull distribution for wind frequency and spatial wind mapping using ArcGIS 10.3.1 with Inverse Distance Weighted (IDW) interpolation for years 2008-2017 of selected stations are analyzed. The results of power law reveal that, among the selected stations, Sittwe in Rakhine State, Thaton in Mon State and Kaw Thaung in Tanintharyi Region have higher mean wind speeds than any other selected stations. In addition, Weibull distribution also proves that more stable and higher mean wind speeds of these stations of 2.46 m/s, 1.82 m/s and 1.71 m/s with shape parameters of 3.10, 6.54, and 6.64, respectively. Lastly, spatial wind map shows that wind speed in Mon State is an increasing trend while wind speed in Rakhine State and Tanintharyi Region is a decreasing trend during the ten years study period.
