Colombo Future Trends
Sri Lanka · Asia · Trend-based projections to 2050
This page uses Colombo's own 50 year weather record to project one trend line forward to 2030, 2040 and 2050, with a Best and Worst scenario range built from the trend's own statistical uncertainty. For where that trend has already gone, see the Climate Capitals Trends, or for current and historical day-to-day weather, see Meteo Capital Cities.

Frequently asked questions about Colombo's projected trends
How warm will Colombo be in 2050?
Extrapolated from Colombo's own record since 1976, the average daytime high in 2050 works out at roughly 29.6°C, down 0.1°C from 2020. This is a straight-line projection of measured weather data, not a climate model or a scenario-based forecast.
How certain is the temperature projection for Colombo?
The 2050 range runs from 29.2°C to 30.0°C. That spread comes from the 95% confidence interval on the trend line's own slope, so the noisier Colombo's record, the wider the band. The trend accounts for 0% of the variation between years; the rest is ordinary year-to-year swing.
How many days above 30°C will Colombo get in 2050?
The trend line lands on roughly 116 days above 30°C a year in 2050, against 134 in 2020. So no increase here, which means the warming in this city sits in the milder months rather than the summer peaks.
Will Colombo still get frost in 2050?
Colombo already recorded no frost days in 2020, and the trend line does not change that. Frost is not a useful measure here, though the heat figures above are.
Is Colombo getting wetter or drier by 2050?
The trend line lands on roughly 3071mm of precipitation a year in 2050, against 2280mm in 2020, so wetter. An annual total says little about distribution though: the same rainfall can arrive in shorter, harder bursts, and that is what loads drains and water storage.
Will Colombo get more sunshine by 2050?
The trend line lands on roughly 3339 sunshine hours a year in 2050, against 3529 in 2020, so less sun. Sunshine hours bear directly on rooftop solar yield, though heat works against it at the same time: a panel loses efficiency at high temperatures.
