Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023
For Sri Jayawardenapura-Kotte, Sri Lanka, the climate data describe 2013–2023. Monthly mean temperatures remain within a narrow range in the supplied facts, while daily rainfall and sunshine averages show clearer month-to-month variation. These figures give a broad picture of typical conditions, not a forecast for any particular day; the rainfall values are daily means rather than monthly totals, and the temperature values are not daytime highs.
Climate overview
Temperature
The monthly mean temperature reaches its supplied high in April at 27.4 °C, while its supplied low is in December at 25.6 °C. These are averages for each month, not daytime maximum temperatures, so they describe the broad monthly pattern rather than the range visitors might experience from day to day. Across the calendar-month means, the unweighted mean is 26.5 °C. It is a summary of those monthly averages, not a day-weighted annual average.
Rain
Mean daily rainfall is highest in October, at 12.85 mm/day. Visitors considering plans for that month should allow for the possibility of rain and keep arrangements flexible; the daily mean does not show how often rain falls or guarantee a wet day. The lowest monthly mean for daily rainfall occurs in February, at 2.15 mm/day, which can be a conditional option for visitors prioritising lower average rainfall. The unweighted mean of the monthly daily-rainfall means is 7.69 mm/day; none of these figures is a monthly rainfall total or a promise of dry weather.
Sunshine
Mean daily sunshine duration is highest in March, at 10.49 hours/day, and lowest in November, at 7.89 hours/day. These averages may help with outdoor planning, but sunshine duration is not the same as day length and does not guarantee the conditions on a particular day. The unweighted mean across the monthly sunshine averages is 9.28 hours/day hours per day. This is a summary of monthly means, rather than a day-weighted annual figure.
Best Travel Time Guide for Sri Jayawardenapura-Kotte, Sri Lanka: Ideal Seasons and Weather Insights
For visitors prioritising cooler monthly averages, December is the relevant option in the supplied temperature pattern, with a monthly mean of 25.6 °C. This is not a daytime high, and it cannot describe the temperature at every hour, so use it as a broad planning reference rather than a guarantee of how a particular day will feel. If lower average rainfall is your priority, February is the conditional choice, with mean daily rainfall of 2.15 mm/day; that average does not quantify rain frequency or ensure dry days. In contrast, mean daily rainfall is highest in October at 12.85 mm/day, so flexible plans and rain-ready clothing are sensible considerations for travel then. For outdoor sightseeing planned around average sunshine duration, March has the highest supplied mean at 10.49 hours/day hours per day, while November has the lowest at 7.89 hours/day hours per day. These are averages, not guarantees of clear skies or measures of daylight length, and the rainfall and sunshine criteria point to separate considerations rather than a single best month.
