A wide-area wildfire suppression system uses a network of geographically distributed water sprayers, and includes at least one wind sensor and a fire-suppression controller communicatively coupled to the water sprayers and the at least one wind sensor. The at least one wind sensor detects wind direction and communicates wind-direction information to the fire-suppression controller, which uses the wind-direction information to activate at least one of the water sprayers upwind of an asset or area to be protected. Parameters of the water spray, such as flow rate, droplet size, spray pattern, spray direction, spray elevation, or aeration, can be adapted based on wind direction or wind speed.
