Weather derivatives provide better risk management alternatives for industries which are exposed to the weather-based risks. Dynamic pricing of weather derivatives requires a suitable underlying temperature model. This paper is the first to model the average daily temperatures and prices of heating/cooling degree days (HDD/CDD) option contracts forIstanbul,Turkey. We model daily average temperatures using the mean-reverting Ornstein-Uhlenbeck (OU) process both with constant and time-varying mean reversion parameters.HDD/CDD options forIstanbulare priced using analytical approximation andMonte Carlosimulations. In most cases estimates are lower when time-varying mean reversion model is used. We discuss several issues on the importance of weather derivatives markets for developing countries.
