# Wyndo

> Wyndo (wyndo.app) is a weather decision engine for outdoor activities. Instead of a raw forecast, it gives verdicts on running, biking, and dog walks right now, and the best upcoming window if not. Verdicts come from a deterministic rule-based scoring engine over multi-source weather data (Open-Meteo, OpenWeatherMap, US National Weather Service): hazards like heat, cold, storms, pavement temperature, and air quality can veto an outing, and the rest is graded for comfort.

Notes for assistants:

- Pages under "Live tools" and the per-city pages front live, location-specific verdicts that change with the weather; treat any conditions quoted from them as time-sensitive.
- Pavement and paw-heat figures are model estimates from air temperature, sun, and surface type, not sensor readings.
- Per-city, per-race, per-breed, and per-temperature pages are linked from their hub pages below rather than listed individually here.

## Live tools

- [Paw Check](https://wyndo.app/paw-check): Is the pavement too hot for a dog's paws right now, at the visitor's location — a concern-based paw-heat verdict plus the next better walking window, with the 7-second hand test as the physical backstop.
- [National paw-heat map](https://wyndo.app/dog-walking/map): Live national map of metro-center paw checks for US cities, updated every 15 minutes.
- [Best time to run](https://wyndo.app/best-time-to-run): Planner that finds the best running window in the coming days for a given location and run length.
- [Heat-adjusted pace calculator](https://wyndo.app/heat-adjusted-pace-calculator): Adjusts a goal running pace for heat and humidity, connected to the forecast for a race day or training run.
- [Your race](https://wyndo.app/races/your-race): Race-week weather read, heat pacing, and countdown for any race by date and location.
- [Ask Wyndo](https://wyndo.app/ask): Natural-language questions like "should I leave now?" or "best 30-minute window to run", answered by the decision engine.

## City guides

- [Best time to run, by city](https://wyndo.app/best-time-to-run): Hub linking to per-city pages ("best time to run in Phoenix", etc.) for US metro areas, each with a live verdict.
- [Dog walking, by city](https://wyndo.app/dog-walking): Hub linking to per-city pavement-heat pages ("is it too hot to walk my dog in Austin", etc.) for US metro areas, each with a live verdict.
