The annual number of tropical cyclones moving into Thailand over 69 years from 1951 to 2019 were studied. The aim was to evaluate preliminary data and determine best-fit distribution. Results were that mean annual number of tropical cyclones moving into Thailand was 2.8986 units, with a standard deviation of 1.9937 units. The data was well represented by negative binomial distribution. The maximum likelihood estimation (MLE) was used for parameter estimates. Estimated values for r and parameters were 8.9991 and 2.8986, respectively.
