Contents:
Periodic water temperature data for 254 New Zealand flow recorder sites for which more than thirty measurements have been made are assembled. For each site, best-fit sine curves have been fitted to the observations, to show how mean daily temperature varies through the year. Plots of the temperature data and the best-fit curves for all 254 sites are presented, and the parameters of the curves, together with minimum and maximum recorded temperatures, are tabulated. Easily measured catchment characteristics have been used in an effort to develop a simple statistical model which may be employed to predict the temperature regime at a site for which no data are available. Mean temperature is predictable from catchment latitude and mean elevation, and the phase shift coefficient of the sine curve has a remarkably constant value throughout the country. However, no simple model can predict either the amplitude of or the scatter of points around the sine curve; these must be estimated from inspection of the plots presented in the report
