      A study has been carried out by comparing the extreme wind speeds estimated based on NCEP/NCAR reanalysis data for 100 years return period using Fischer Tippet-1 (commonly known as Gumbel)and Weibull distributions for three locations (off Goa,Visakhapatnam and Machilipatnam)in the north Indian Ocean.The wind dataset for Goa is compared with that from ERA-40 data.For higher wind speeds ($12-20 m s^{−1}$ ),NCEP wind speed has higher percentage of occurrence than that of ERA-40.Analysis has shown slight upward trend in the annual maximum wind for location off Machilipatnam with an increase of $1.2cms^{−1}$ per year and a decreasing trend of $−1.3cms^{−1}$ per year in the case of Goa.The Weibull distribution with shape parameter 2 fits the annual maximum wind data better than FT-1 distribution.
