About Nature Says When
Nature Says When is a free outdoor planning website for the United States. Choose an activity and search for a city, state, or ZIP code to compare useful times to head outside. The site brings together weather, air quality, and other environmental conditions so you can assess a plan without comparing several separate forecasts. Use it when deciding when to take a walk, plan an outdoor outing, or check conditions in another city. Activity guidance and local forecasts help explain the tradeoffs behind a suggested time. Conditions and forecasts can change, so the recommendations are planning guidance rather than a guarantee of safety. Nature Says When is a consumer web tool, not an emergency service.
