I have an older version of Weewx and as such, older versions of the plugins. This post references the forecast.inc plugin version 3.2.14 but it might be helpful for later versions also.
My forecast.py plugin stopped working and my syslog showed this forecast: NWSThread: NWS: downloading forecast from 'http://forecast.weather.gov/product.php?site=NWS&product=PFM&format=txt&issuedby=MLB' Aug 2 20:22:15 weather weewx[1091]: forecast: NWSThread: NWS: failed attempt 1 to download NWS forecast: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)> This is what fixed it. I went to the forecast.py source in /usr/share/weewx/user added import ssl in the import section of the code and then added this in the def NWSDownloadForecast(foid, url=NWS_DEFAULT_PFM_URL, max_tries=3): function ctx = ssl.create_default_context() ctx.check_hostname = False ctx.verify_mode = ssl.CERT_NONE response = urllib2.urlopen(u, context=ctx) """below is the original now commented out source line""" """response = urllib2.urlopen(u)""" Now my forecast is working perfectly fine.
