Conky is a simple system monitor that uses very little ram.

I have 2 conky-rc files: a system monitor and a weather display.

I wrote my system monitor from scratch and my weather display is based on this tutorial.

Replace ~/.conky/conkyForecast.py with the location of your weather script. Replace USCA0638 with your city code (see the tutorial link at the beginning of this post).

Conky weather script

#!/usr/bin/python
# -*- coding: utf-8 -*-
###############################################################################
# conkyForecast.py is a (not so) simple (anymore) python script to gather 
# details of the current weather for use in conky.
#
#  Author: Kaivalagi
# Created: 13/04/2008
# Modifications:
# 14/04/2008 Allow day ranges for forecast data
# 14/04/2008 Check for connectivity to xoap service
# 18/04/2008 Allow the setting of spaces for ranged output
# 18/04/2008 Allow Night and Day forecast output
# 18/04/2008 Support locale for condition code text "CC" option, awaiting spanish language translation
# 18/04/2008 Use pickling for class data rather than opening xml, this bypasses the need to interrogate cached data
# 19/04/2008 Added spanish condition text - Thanks Bruce M
# 19/04/2008 Added isnumeric check on all numeric output with units suffix
# 19/04/2008 Altered pickle file naming to include location code
# 19/04/2008 Added spanish week days conversion via locale
# 20/04/2008 Added decent command argument parser
# 20/04/2008 Added --shortweekday option, if given the day of week data type is shortened to 3 characters
# 21/04/2008 Fixed locale options for forecast output
# 21/04/2008 Added --template option to allow custom output using a single exec call :)
# 21/04/2008 Added --hideunits option to remove, for example, mph and C from output
# 23/04/2008 Removed --imperial option from template, this MUST be set as a standard option on the script call and not used in the template file. 
# 23/04/2008 Readded --imperial option to template, enabling metric or imperial values per datatype. Note when using templates command line option will not work.
# 23/04/2008 Added output notifying user if the location given is bad
# 24/04/2008 Added handling for no connectivity, will revert to cached data now (erroring if no cache exists). Tests by trying to open xoap.weather.com
# 24/04/2008 Fixed Celsius to fahrenheit conversion
# 06/05/2008 Updated url used after webservice was updated
# 09/05/2008 Consolidated current condition and forecast data fetch into one call
# 09/05/2008 Added Sunrise and sunset to datatypes, these are specific to both current conditions and forecast data
# 09/05/2008 Added moon phase, barometer reading and barometer description to datatypes, these are only specific to current conditions and so are N/A in forecasted output
# 09/05/2008 Added unit conversions for barometer from mb to inches (imperial)
#   09/05/2008  Updated spanish condition text - Thanks Bruce M
#   10/05/2008  Added french locale data - Thanks benpaka
#   12/05/2008  Added new BF (bearing font) datatype to provide an arrow character (use with Arrow.ttf font) instead of NSEW output from WD (wind direction)
#   12/05/2008  Updated WD output to be locale specific, currently supports default english and spanish - Thanks Bruce M
# 18/05/2008 Added new MF (moon font) datatype to provide a moon font character (characters incorrect and no dedicated font yet).
# 21/05/2008 For current conditions the --datatype=LT option now displays "feels like" temperature rather than the current temperature
#
# TODO:
# Consolidate pkl files into one file/class
# Add a weather font based moon phase output based on moon icon data
# ??? Any more requirements out there?
