Maharashtra's state heat wave action plan, issued in Marathi by the Disaster Management Department under the Disaster Management Act 2005 framework. Public-health alert overlay only: the plan states on printed page 34 that its instructions are advisory in nature ('सदर सूचना या मार्गदर्शक स्वरूपाच्या असून'), and it publishes no WBGT value, no wet-bulb value and no work/rest schedule. Read in full from the primary Marathi PDF on 2026-07-31; see docs/research/maharashtra_hap-2026-07-31.md for every threshold with its Marathi quote, translation and page citation.

The drag-to-check calculator needs JavaScript. Every value it can show is a row of the table below, which is computed by the same engine.
No standalone formula is published for this standard; see programmable logic and parameters below.
Plains absolute-temperature criterion only. The terrain-specific and departure-from-normal heat-wave criteria the plan also publishes are not evaluated — this calculator has no region-type or seasonal-normal input.

Only plainsHeatWaveAbsoluteThresholdC (45C) and plainsSevereAbsoluteThresholdC (47C) drive the alert level.
The terrain thresholds (40/37/30C, printed pages 9 and 25) and the departure-from-normal criterion (4.5-6.4C / >6.4C, printed page 10) are published criteria carried for traceability but not computed -- no region-type or seasonal-normal input exists. advisoryMiddayAvoid 12:00-15:00 (printed pages 35, 36 and 71) is citizen-facing public-health advice, never composite-entering. flexibleHoursAgeThresholdYears (printed page 29) is not computed -- no worker-age input.
The plan's separate 14:00-16:00 window concerns permits for marches and demonstrations, not work, and is intentionally absent from this table.
Required inputs: maxTempC
