Sea weather forecast from the DWD


The German weather service sends sea-weather forecasts for the next 24 hours, 2-day-forecasts and 5-day-forcasts in German language on the long wave frequency 147.3 kHz.


Synop Messages

In addition to the well-known weather messages the DWD sends encoded meteorological data of firm weather stations and ships.


The PC Software for the WIB3S decodes these data and indicates it in a map as wind arrows.


Additionally the Synop-data can also be indicated in plain text on PC:


Call sign: 62133
Day: 2 Hour: 12h
Latitude of observation: 57.1 degrees.
North east.
Longitude of observation: 1.0 degrees.
Precipitation omitted, no observation.
Automated station, omitted, no weather observation.
Cloud base of lowest cloud seen (meters above ground): unknown.
Visibility: missing.
Total cloud cover: no observation.
Wind speed: 18 Knots (from anemometer).
Wind direction: 320 °.
Temperature: 9.9 °C.
Dewpoint: 2.1 °C.
Sea level pressure: 1010.7 hPa.
Pressure change over 3 hours: 4.1 hPa
Pressure tendency over 3 hours: Increasing steadily, resultant pressure higher.
Direction of ship movement: Calm.
Ship's average speed: 0 Knots.
Period of waves: 5 s.
Height of waves: 1.1 m.
Wave heights (instrumented): 1.8 m.
Wet bulb temperature: 6.6 °C.



With the help of the internal precision-air-pressure-sensor the air pressure will be stored during a period of max. two days PC seven days).
The air pressure process can be indicated on the PC in form of a gradient.


NAVTEX from the costal radio stations


The equipment is able to receive world-wide the NAVTEX messages of the costal radio stations on the frequencies 490 kHz and 518 kHz. The messages on 518 kHz are sent in English language and on 490kHz they are sent in the respective national language.

The range of the NAVTEX- transmitters varies in dependence of the transmitting power.

NAVTEX messages include e.g.:

  • Nautical warnings
  • Distress messages
  • Weather forecasts
  • storm warnings
