What Is a Weather Facsimile Receiver?

A Weather Facsimile Receiver (Weather Fax) is a marine communication device that receives weather charts transmitted by meteorological stations through radio frequencies.

These charts include:

  • Surface Pressure Analysis
  • Weather Forecast Maps
  • Tropical Cyclone Warnings
  • Typhoon Tracking Charts
  • Wind Forecast Charts
  • Wave Height Forecasts
  • Sea Surface Analysis
  • Ocean Current Information

Before satellite internet became widespread, Weather Fax systems were one of the most important weather information sources for vessels at sea.

Even today, many operators continue using weather fax systems as a reliable backup weather information source.
