Voyager IRIS brightness temperature measurements of Titan at a wavelength of 530 cm−1are crudely indicative of ground or lower tropospheric temperatures and indicate 93 K for the equator and 91 K for both northern and southern high latitudes. The symmetry between north and south is unexpected for the time of Voyager encounter (Northern Titan spring). We show that this near‐symmetry can arise naturally in a model where the poles are "pinned" year‐round at the dew point of CH4‐N2lakes or, more probably, a CH4‐N2rich surface layer on a deep ethane‐rich ocean. For a polar temperature of 91 K, the model implies that the atmosphere contains somewhat less than 8% mole frac
