Climate overview
Temperature
The highest monthly mean temperature is recorded in February, at 26.8 °C. By contrast, the tied coolest monthly means occur in July / August, at 22.1 °C; the monthly-mean figure across the calendar months is 24.7 °C. These measures describe typical month-level temperatures, not daytime maximums or the range visitors may encounter from day to day, so they are best used as broad seasonal-planning context rather than a promise about any particular day's conditions.
Rain
Mean daily rainfall reaches its highest monthly average in January, at 7.19 mm/day, while the lowest is in September, at 0.77 mm/day. The unweighted mean of the monthly figures is 2.73 mm/day. These are daily average amounts, not monthly totals, and the lower figure does not mean that every day in that month is dry or indicate how often rain occurs. The contrast is useful when choosing a rainfall-related planning criterion, but it cannot guarantee conditions for an individual visit.
Sunshine
Mean daily sunshine duration is highest in December, at 11.76 hours/day, and lowest in June, at 9.59 hours/day. Across the calendar-month means, the unweighted figure is 10.62 hours/day per day. These averages can help with broad outdoor-sightseeing plans, but sunshine duration is not the same as day length and does not promise uninterrupted sun on a given day.
Best Travel Time Guide for Port Louis, Mauritius: Ideal Seasons and Weather Insights
If lower average rainfall is your priority, September is the conditional option indicated by the lowest mean daily rainfall, 0.77 mm/day; this does not guarantee dry days or describe rain frequency. For a visit in the month with the highest mean daily rainfall, January at 7.19 mm/day, plan for the possibility of rain and bring suitable protection. These figures are averages, not a forecast for your travel dates. Visitors prioritising cooler monthly averages can use July / August as a guide: its tied monthly mean is 22.1 °C, rather than a prediction of daytime highs or daily variation.
