What does the weather information in my TripPlan represent?
The weather information you see in your TripPlan is based on historical averages for that day over the past 25 years. You’ll see average low and high temperatures for that day, plus an icon to indicate an above-average likelihood of precipitation (snow or rain) or high winds. Please note that historical average weather data is not the same as a weather forecast, which can vary greatly from historical conditions. Because forecast information is generally only available for the next week, TripIt uses historical averages to help you plan for weather far in advance of your trip.
