Weather derivatives are contingent claims with payo based on a pre-specied weather index.
Firms exposed to weather risk can transfer it to nancial markets via weather derivatives. We
develop a utility-based model for pricing baskets of weather derivatives in over-the-counter
markets under counterparty default risk. In our model, agents maximise the expected utility
of their terminal wealth, while they dynamically rebalance their weather portfolios over a
nite investment horizon. Via partial market clearing, we obtain semi-closed forms for the
equilibrium prices of weather derivatives and for the optimal strategies of the agents. We
give an example on how to price rainfall derivatives on selected stations in China in the
universe of a nancial investor and a weather exposed crop insurer.
