This document provides instructions for reading a weather map and understanding key elements such as air pressure, wind direction and speed, temperature, and dew point. It explains that air pressure between 94.00 kPa and 106.00 kPa is generally acceptable, how to convert between kPa and millibars, and that changes in air pressure indicate incoming weather patterns. Wind direction is shown by the direction the point of the wind barbs face, and speed is represented by full and half barb increments of 10 and 5 knots respectively. Temperature and dew point are both measured in degrees Celsius.
