Living in Colombo means living under Sri Lanka's tax and legal system. The essentials, from our country research:
Would Sri Lanka actually work for your taxes?
It runs regimes like Foreign Service Income and Foreign Source Income 15% Concessionary Rate, and whether they fit depends on your income, assets and citizenship, not on averages.
Each month scores 0 to 10 from four weighted components: temperature (35%), sunshine (25%), humidity (20%) and rain (20%), with an extra penalty when heat and humidity combine. Personal tolerances reshape the score: your heat limit compares to how afternoons feel (heat index), your cold limit to typical nights. Data: NASA POWER climatology 2001-2020 with elevation corrections, daylight computed from latitude.
