The forecast beside every event, not just the day

Most calendars that mention weather show one icon per day. That icon is an average, and an average of a wet morning and a dry afternoon is a drizzle that never happens.

What most people assume

That a daily weather icon on a calendar is the same feature as a forecast attached to an event.

What a daily icon hides

Take a day that rains hard until eleven and stays clear afterwards. The daily summary picks something in the middle and shows a cloud. You look at your two o'clock, see the cloud, and move a walk that never needed moving.

The error runs both ways. A day that is fine except for a violent hour at six shows as fine, and the one event that mattered is the one that gets caught.

Attaching the forecast to the hours

An event occupies specific hours. The forecast for those hours is a different number from the forecast for its day, and it is the only one that answers the question you are actually asking.

Open an event and the conditions shown are the ones for its window. A three-hour block gets the three hours, not the twenty-four.

What to do

  1. Check the event, not the day, whenever the plan depends on the weather.
  2. For anything longer than a couple of hours, look at how the conditions move across the block rather than at a single figure.
  3. Move the event before you cancel it — an hour either way is often the whole difference.
