Methods of controlling tint of a tintable window to account for occupant comfort in a room of a building. Some methods include receiving weather feed data from one or more weather services (or other data sources) over a communication network, determining a weather condition based on the weather feed data, and determining a tint level for the tintable window based on the weather condition and based on whether a current time is within a time delay period at sunrise or sunset.
