Voyager IRIS brightness temperature measurements of Titan at a wavelength of 530/cm are 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). It is shown that this near-symmetry can arise naturally in a model where the poles are 'pinned' year-round at the dew point of CH4-N2 lakes or, more probably, a CH4-N2 rich 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 percent mole fraction of CH4.
