Systems and methods for determining an effective wind speed are disclosed. A system includes a first detector, a second detector and a processing unit. The first detector includes a heated temperature-sensing element having a heater and a first temperature sensor, and a first housing at least partially housing the heated temperature-sensing element. The second detector includes a non-heated temperature-sensing element having a second temperature sensor, a second housing at least partially housing the non-heated temperature-sensing element. The processing unit can be adapted to determine the effective wind speed according to a temperature at the heated temperature-sensing element, a temperature at the non-heated temperature-sensing element, and/or a difference between these temperatures and in accordance with an algorithm or table of values. The heated and non-heated temperature-sensing elements and their respective first housing and second housing are collinear, proximal and parallel to the conductor, and protected from precipitation by a shield.
