These days remind you to try to avoid RISKY days by more than 24 hours whenever possible. Planning a minimum of 24 hours away from RISKY days has been shown to maximize the forecast accuracy.

RISKY Days

RISKY Days

If rain (or snow) does fall in the month, expect most of it to fall on the risky days. These are not rain or snow forecasts, but weak spots in the month which would more easily allow passage of a storm through the area.

  • Why should I use DRYDAY® forecasts?
    Use DRYDAY® forecasts to plan all of your weather sensitive activities. Using these forecasts will greatly increase your odds in choosing a day without rain or snow.
  • How do I use the forecast to plan my activities?
    The height of the bar represents the percentage risk of rain/snow. Therefore, plan your activity on the lowest DRYDAY® day (gold bars), as far away from risky days as possible. If there are no DRYDAY® days in the forecast, choose the lowest bar possible or plan during another period.
  • Do you forecast for my location?
    You can select from over 1.2 million cities in 183 countries. To find a specific city prior to purchase, use our location search tool.
  • How accurate are the forecasts?
    While no weather forecast is perfect, DRYDAY® forecasts have been shown to be up to 85% accurate in identifying dry periods in the weather.
  • How do DRYDAY® forecasts differ from traditional weather forecasts?
    DRYDAY® forecasts are designed to forecast dry days, days in which there is little risk for rain or snow. They do not forecast when it will rain (or snow), or how much rain/snow will occur. Unlike traditional forecasts, DRYDAY® forecasts are long range and never change.
