Weather/Climate Data

I'm not sure where this topic belongs - so I apologize if I'm posting in the wrong spot. Can I move it if it needs to be somewhere else?

I'm a bit of a science geek when it comes to my planning but I'm a little frustrated (I'm on limited sleep so I'm also a bit cranky and impatient) and I'm hoping you guys can point me in the right direction.

It seems that all I can find is regional weather data that was last updated in 2010. Is this to be expected?  Maybe the local climate isn't much different now than it was 10 years ago (chuckling) but I would LOVE to review more recent data on average monthly rainfall amounts, annual ACTUAL frost free dates etc. just to see what's really going on. I swear it's been warmer earlier in recent seasons and our rainfall patterns have been truly wacky and I want to seek if this is a new trend or part of a normal cycle.

Does this data exist?

I'm digging through the obvious sites but keep landing on that 2010 date. Maybe they're about to update things to 2020?

Share anything you know, I've only just begun to look so I have fairly limited knowledge.

Weather Underground provides monthly tables of Temperature, Dew Point, Humidity, Wind Speed, Pressure & Precipitation back to the 50’s.

You can really run down some rabbit holes when looking at weather data. For grins after a customer conversation we compared forest fire data from the dust bowl 30's to contemporary data. Is it an accurate comparison with the technology we have at hand today? Maybe.
Does or will development current or planned affect a micro climate of properties adjacent to that development? I remember watching a cloud bank approaching a military parade field of asphalt and the cloud bank separated from the heat and re-combined after it passed over the super heated plume of air.
What was once permeable ground covered with an impermeable surface and that water moved elsewhere.
Reduction of trees to a field can be as disruptive as concrete perhaps since it changes the temperature.
The scientific prediction of a coming ice age of the 1970's, a one off volcanic eruption that creates a summer that never occurs.
If humans weren't so adaptable they might make better or maybe more thoughtful long range decisions.

Awesome! It even does Canada (or at least the part of Canada I live in, although it's using some archaic measuring system. Good thing I'm mostly bilingual.)
