This report illustrates the typical weather in Port Louis, based on a statistical analysis of historical hourly weather reports and model reconstructions from Januto December 31, 2016. Our beach/pool temperature score is 0 for perceived temperatures below 65☏, rising linearly to 9 for 75☏, to 10 for 82☏, falling linearly to 9 for 90☏, and to 1 for 100☏ or hotter. Our tourism temperature score is 0 for perceived temperatures below 50☏, rising linearly to 9 for 65☏, to 10 for 75☏, falling linearly to 9 for 80☏, and to 1 for 90☏ or hotter. Our precipitation score, which is based on the three-hour precipitation centered on the hour in question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 0.04 inches of precipitation or more.

Those scores are combined into a single hourly composite score, which is then aggregated into days, averaged over all the years in the analysis period, and smoothed. The beach/pool score (filled area), and its constituents: the temperature score (red line), the cloud cover score (blue line), and the precipitation score (green line).įor each hour between 8:00 AM and 9:00 PM of each day in the analysis period (1980 to 2016), independent scores are computed for perceived temperature, cloud cover, and total precipitation.
