For calculations of evaporation losses by mass transfer techniques, and for many other research and operational applications, it is necessary to know the mean patterns of surface water temperature. The work of Millar [1952] has been widely used whenever such information is required for the Great Lakes. This paper presents preliminary patterns of monthly mean surface water temperatures for Lake Ontario based on 36 airborne radiation thermometer surveys over a three‐year period. Temperature values at each of the 89 points in a grid have been plotted against calendar date, and an annual temperature curve has been produced for each point. Values for the middle of each month have been determined by interpolation, and used to produce a pattern for each month. The patterns are briefly compared with Millar's. Over the next few years as the airborne radiation thermometer (ART) surveys continue to add to the data bank, it is planned to update these analyses. Therefore these monthly values must be considered tentative at this time.
