Every table behind GMM’s analysis of flooding in Malé: monthly rainfall 1975–2025, flood events 2018–2026, the 21 October 2026 storm, census population, drainage and sewer parameters, funding, concentration indicators, the calculations log and the sources manifest, plus GMM’s derived series (anomalies, rankings, trend tests, season totals, sea level) and the raw tide-gauge and daily-rainfall files used.
Known issues: the 2025 rainfall total does not equal the sum of its months (219.6 mm gap); the yearbook gauge is labelled Malé without naming the station; the GHCN daily file is too incomplete for trend analysis; UHSLC fast-delivery data are not quality-controlled.
A 90 mm storm flooded Malé on 21 October 2026. GMM's analysis of 51 years of rain, the tide gauge and the drains finds an island that has lost the capacity to cope, and sets out how to rebuild it without stopping the city.
