 note = {From a viewpoint of establishing a rational design formula for wind loads for buildings, the reference wind pressure is not to be based on the largest instantaneous wind speed experienced so far, but on analysis of an annual series of extreme wind speeds. The paper deals with analysis of annual extreme mean wind speeds obtained at seven meteorological stations in topographically isolated islands of Okinawa, and presents a tentative discussion for the reference wind pressure.\nThe series of annual extreme mean wind speeds at each station has shown to be well fitted by double exponential distribution. The statistically expected annual extreme mean wind speeds in 50 years of return period at each station have been calculated, and result in 53.6, 51.5 and 61.0 m/s for Naha, Ishigaki and Miyako, respectively. As a consequence of this study, the reference pressures (kg/m^2) of 120 √^4<h>, 200√^4<h> and 260 √^4<h> (h; height in meter) have been tentatively proposed for Daitoh, main island of Okinawa and Ishigaki, and Miyako, respectively, taking the same value of 2.0 for gust effect factor as in Canadian Code for the consideration of the effects of gusty winds., 紀要論文},
