A model to estimate the duration of condensed water on the surface of cocoa pods after sunrise is modified to use readily available meteorological data. Changes in wind speed, air temperature and humidity with height and time in a cocoa plantation are presented. Pod temperature and the amount of condensation calculated from the maximum and minimum temperatures and humidity at 0900h agree well with measured values. The effects on pod wetness of changing pod size, short‐wave radiation and wind speed are investigated.
