HeatSmart Houston
A hyperlocal hour-by-hour planner that reschedules outdoor tasks (dog walks, lawn work, runs, July 4th plans) into safer windows and warns you the moment the heat index crosses your personal risk threshold.
Houston residents planning outdoor activities in extreme heat
- Personal risk profile (age, medications, AC access) calibrates the alerts and timing
- Plan-mode: enter 'fireworks at 8 pm' and receive hydration, attire, and transit timing advice
- World Cup fan-fest integration with shaded-route navigation and cooling-station locators
- Heat-illness symptom checker that distinguishes heat exhaustion from heat stroke and tells you when to call 911
Houston is under a July 4th heat advisory with feel-like temps 106-110, coinciding with the World Cup fan fest and outdoor Independence Day plans; locals are actively planning around it.

OSHA-NIOSH Heat Safety Tool (free, gov-backed), NWS HeatRisk, and Weather Channel Premium all already cover hourly heat-index planning — consumer-side rescheduling for Houston-specific activities is a thin slice on top of crowded infrastructure.Heat Safety Tool App (OSHA-NIOSH) | Heat Stress | CDC ↗Heat Forecast Tools - National Weather Service ↗
Weather Channel Premium proves $29.99/yr weather subscriptions work for general consumers, but free government tools (OSHA-NIOSH, NWS HeatRisk) directly compete; a hyperlocal Houston niche has weak pricing power.What's included in the Premium Subscription? - The Weather Channel ↗Heat Safety Tool App (OSHA, NIOSH) - Heat.gov ↗
Houston heat is structural and worsening with climate change, recurring every summer, but demand is highly seasonal/weather-event-driven rather than year-round utility.Houston World Cup Fan Fest weather: heat, humidity, storms ↗
Public NWS heat-index forecasts plus push notifications and a per-user threshold setting are standard; only differentiation work is Houston-specific event/personalization layer.Heat Forecast Tools - National Weather Service ↗
