About KIAD weather reports

Washington Dulles International Airport issues a routine METAR observation about every half hour, plus a SPECI whenever conditions change sharply. The TAF above forecasts the next 24 to 30 hours within roughly five nautical miles of the field. Both are decoded on this page: the raw code stays visible for anyone who wants it, and everything below it is the same information in plain language, colour and diagram form.

Use the runway diagram to see how the current wind splits into headwind and crosswind on each runway end, the meteogram to plan the next week, and the trend charts to understand what this airport is normally like — how often it goes IFR, which direction the wind usually comes from, and when in the day it tends to turn.
