The wxnow.txt file is created by Cumulus once a minute by default, in the Cumulus program folder, unless you have disabled it by setting


in the [Station] section of Cumulus.ini_(Cumulus_1). Below is the file format, simply for information.

Sample File

This is a simply text file containing two lines of data.

Feb 01 2009 12:34

Format of the file

The first line is the time the file was created in local PC time. Please note that the day of the month, the hour and the minute must be padded to two digits with zeros if needed.

The second line is the wx report, in the format used in APRS "complete weather reports". The format is:

  • 272 - wind direction - 272 degrees
  • 010 - wind speed - 10 mph
  • g006 - wind gust - 6 mph
  • t069 - temperature - 69 degrees F
  • r010 - rain in last hour in hundredths of an inch - 0.1 inches
  • p030 - rain in last 24 hours in hundredths of an inch - 0.3 inches (Cumulus does not supply this value)
  • P020 - rain since midnight in hundredths of an inch - 0.2 inches
  • h61 - humidity 61% (00 = 100%)
  • b10150 - barometric pressure in tenths of a millibar - 1015.0 millibars

From build 1028 of version 1.9.2:

  • Fix negative (F) temperatures

From Build 1097 of version 1.9.4:

  • Selecting APRS/CWOP option to send solar radiation now also adds it to wxnow.txt
  • Pressure in wxnow.txt is now 'altimeter' rather than MSLP
