Diurnal variability of heat fluxes in the coastal waters of Visakhapatnam has been studied during post-monsoon (Oct, 2006) and winter (Jan-Feb, 2007) seasons utilizing the surface meteorological data and radiation measurements on-board CRV Sagar Sukti and mechanized boats. Estimated values of short and long wave radiation are well comparable with the measured values. Latent (Q sub(LH)) and sensible (Q sub(SH)) heat fluxes are computed from bulk aerodynamic method. Total enthalpy (i.e. Q sub(LH)+Q sub(SH)) was 50-200W/m sup(2) and 10-200W/m sup(2) (on diurnal scale), during post monsoon and winter seasons respectively. The net heat exchange (QN) was 137W/m2 and 92W/m2 under the above seasons. Daily mean values of Bowen Ratio (B) in the study region varied between 0.02 and 0.14,. A simple relationship [(B=0.057(Ts-Ta) sup(0.89); N = 20; r = 0.82; significant at > 99% level)] between Bowen’s ratio (B) and sea-air temperature difference has been proposed for unstable conditions. High correlation (r = 0.87) is found between the values of Q sub(LH) estimated and obtained from the above relationship
