Seriously???? You want our winters
Yup! I was born in Saskatchewan SW of Humboldt. I was at the home farm in early February a few years ago. It was amazing! It brought back sooooo many memories...... We talked about stone boats in another thread. How about the Caboose we went to school in during the winter?
Yes, I absolutely love REAL Winters.
But you are right, most easterners would have me drawn and quartered if I ever made that dream come true!
Ya, that part wasn't fun.
But fair is fair. I'll take that over +35°, mosquitos & biting flies in swarms in broad daylight, salty sweat in my eyes and mouth, shirts and underwear soaked in sweat, even the air in the shade of a big walnut tree burns your eyeballs. Yup, I'm dreaming of those gorgeous western winters right now... You can always put on more clothes when it's too cold, but you can't take more off when it's too hot.
Your gauge readings are a great opportunity to talk about relative humidity a bit more. Some have said it's too complicated. But everything is complicated until you grasp the principles. Your gauge says it's:
24.7°C and 32% inside and
29.2°C and 20% outside
From the chart I provided earlier,
100m3 of air at 30°C can hold a maximum of 3L of water. The humidity in your gauge is 20%. 20% of 3L is 0.6L. So the outside air has 0.6L of water in it per 100 cubic meter. That part is pretty straight forward. But let's look at your inside air and do a little interpolation. Your gauge says the outside air is 25°C and 32% relative humidity. Looking at the chart again, and interpolating between 20 and 30, (25 is half way between them) the maximum water at 25 should be roughly half way between the two humidity numbers too. That is approximately a maximum
2.4L of water. Your gauge says 32%. And 32% of 2.4 is approximately. 0.76 L of water! Given that the relationship isn't really linear, that I rounded the numbers off, and given the poor accuracy of most humidity gauges, thats pretty darn close to the same amount of water as outside!
In other words, the amount of water in the air didn't change (nor should we expect it to). However because it's colder inside, the air can't hold as much water as it could when it's hotter so the relative humidity goes up from 20% to 32%.
Now, just imagine what it would be like if you had 95% humidity OUTSIDE at even higher temperatures ......... And "Welcome to my world"!
I love math, and seeing a graph or spreadsheet of numbers always makes me want to extrapolate info from the data. I looked at the Calgary humidity chart and went “hmm”. I’ve only spent a little time in Calgary, but Vancouver doesn’t have sagebrush or rattle snakes, so Calgary <should> be dryer than Vancouver. So I looked for a similar chart using Vancouver data.

Turns out we rarely drop below 50%, which explains why my air conditioners crashes in the middle of the night, when the sump fills with condensate and trips the high-level alarm.
Could be worse, we could live in Toronto.

Fantastic data! I used to look at this year's ago, but lost my links to it. THANK YOU for finding them!
For some reason they don't have the numbers for Windsor or Essex or Leamington (or I wasn't able to find them). These cities should have the worst humidity in Canada. Maybe they don't want us to know that.......
Never Mind, found it. It was just well hidden. See next post.

Update - I bought some WD-40 Specialist Corrosion Inhibitor.
It contains a VCI !!! (Volatile Corrosion Inhibitor). That makes it an outstanding long term corrosion protection coating.
The can says it protects for 1 year.
I think my search for bulk VCI is over. If this works like I think it does, I should be able to lightly spray my tools once a year and be done with them. A VCI is what is impregnated in those cards and wrapping paper that is used in tool shipping. It works by volatolizing a corrosion Inhibitor that is subsequently attracted to microscopic pores and cracks in the grain structure of metals which stops corrosion in its tracks. It will even work for tools in boxes and drawers. I can give each drawer a light spray and walk away.
After checking the details, and trying out a can of it on something prone to rusting (eg my plow blades) , I'll prolly order a case of it.

Canadian Tire. But you can get it on Amazon too. Apparently they sell other "specialist" products. So make sure the can says "VCI".

Weird...I asked because I searched the Canadian Tire web site and couldn't find it. As you say, there were quite a few "WD-40" products. I'll go back and make sure I wasn't just searching one store.

My goto penetrant is deep creep too. And my goto storage film is Fluid Film.
So I am REALLY ANXIOUS to try the WD-40 VCI product!
While looking at the VCI stuff, I did notice that WD-40 is selling a specialist penetrating fluid now too. I have no idea how well it compares to deep creep. But everything can improve and I am always open to changes.
Apparently I led you on a wild goose chase Craig. Sorry about that. I couldn't find it at CTire either. So I figured maybe they discontinued it or it was a special. They do sell a WD-40 Rust Release product and I do have a can of that too that I thought I got at Amazon. I'll come back to this in a minute.
So I did a broader search and found it at lots of places including Walmart, and Amazon. I'm not fond of Walmart (I always feel like somebody is taking my picture) so I checked out amazon. They kindly pointed out that I had recently purchased some...... Duh.....
WD-40 300038 Specialist Long Term Corrosion Inhibitor Spray 6.5 OZ (Pack of 1) https://www.amazon.ca/dp/B00631GWS4/ref=cm_sw_r_apan_i_RW7XTZFEDMP12RNQYKHD
So now I'm thinking I bought the WD-40 Rust Release product at Canadian Tire and the Rust Inhibitor at Amazon and just confused the two.
Sorry about that.
@Susquatch said, so now I'm thinking I bought the WD-40 Rust Release product at Canadian Tire and the Rust Inhibitor at Amazon and just confused the two.
You know what they say about being confused, now I've forgot what they say! Help! LOL

My wife like to say that the more certain I am about something, the more likely it is that I am just confused again......
The only thing I am certain of is that I am confused most of the time, well some of the time I guess, but now that I think about it maybe not.
At $47 a can you want to make sure you put that away for special occasions, label looks to similar to regular wd40.

It gets worse, it's also a very small can.
On the other hand, if it saves a drawer full of tools it pays for itself many times over.
I'll guess it can be had for less and that it will also come down as time passes. But who knows. I'd appreciate knowing about better deals.
I'm still on the hunt for volume VCI.
