Colombo
Heat context: Humid lowland/coastal urban heat; night recovery matters. National station trends and modelled evening/night exposures are distinct.
Official heat plan: Status note: No signed/current city-specific HAP retrieved in this review; absence from collected evidence is not proof none exists.
Money for protection: Note: National/project routes do not establish municipal eligibility, expenditure or ward coverage.
A place to start (proposed): Co-design market/street-worker protection with reliable water/toilets, shade, rest without income loss, consent-based monitoring and night/home follow-up.
Known: Documented reason to investigate heat in this location/region.
Inferred: Local action is likely to work best when it combines physical protection, livelihoods, services and maintained delivery.
Uncertain: Ward exposure, current approved plan, operating facilities, budget, outreach and protection outcomes.
Selection basis: Original worker fieldwork, urban model/data and institutional heat-planning engagement.
Geographic caution: Selected documented heat-concern case; provincial/district forecast is not citywide measured exposure or a ranking.
