Hello, I was just wondering if if anyone has bothered to track long term trends on dew point temperatures, and if so which years were the most humid I.e. a dew point temperature of 70 or higher. Anyone with links or useful information is greatly appreciated.

Using mean daily dewpoint, here's Phoenix since 2001 (the year I moved here):
2001=3 days (Jul 30th, Aug 9th, Aug 10th)
2002=0 days (warmest mean dewpoint was 69°F on Sept 8th)
2003=0 days (warmest mean dewpoint was 68°F on Aug 27th and Sept 24th)
2004=0 days (warmest mean dewpoint was 68°F on Jul 14th)
2005=3 days (Aug 8th, Aug 9th, Aug 10th)
2006=2 days (Jul 26th, Jul 27th)
2007=0 days (warmest mean dewpoint was 69°F on Jul 31st and Aug 1st)
2008=2 days (Jul 11th, Jul 13th)
2009=0 days (warmest mean dewpoint was 65°F on Aug 22nd)
2010=2 days (Jul 29th, Jul 31st)
2011=0 days (warmest mean dewpoint was 66°F on Jul 25th)
2012=3 days (Aug 22nd, Aug 23rd, Sept 7th)
2013=1 day (Jul 21st)
2014=1 day (Sept 8th)
2015=0 days (warmest mean dewpoint was 68°F on Sept 21st)
2016=2 days (Aug 2nd, Aug 3rd)
2017=1 day (Jul 24th)
2017 had 15 days with a mean dewpoint of 70ºF or higher in OKC and 2016 had 46. I don't know of the most efficient way to find this data; maybe look in the getting record climate data thread.
I could not find any records for Wenatchee, but the comment from weather spark...
The perceived humidity level in Wenatchee, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, remaining a virtually constant 0% throughout.
Dew point above 70 is non-exist and above 60 is also very uncommon in the SF Bay Area due to persistent morning fog.
