20C+ dewpoint days in July and August 2018 according to wunderground:


TOR 18 PHIL 19

TOR 23 PHIL 27

high temps though aren't very high imo.



And one year doesn't tell me anything. I need to see 30 years worth of averages.

You know there's this thing called Google, right? But since I'm a nice guy, I'll save you the trouble and link to the official averages:

Toronto Pearson (inland west end) Canadian Climate Normals 1981-2010 Station Data - Climate - Environment and Climate Change Canada

Toronto City (downtown close to the lake) Canadian Climate Normals 1981-2010 Station Data - Climate - Environment and Climate Change Canada

Toronto Buttonville (NE suburbs)
Canadian Climate Normals 1981-2010 Station Data - Climate - Environment and Climate Change Canada

and here are the warm season (May-Sept) averages for this decade



source EC Monthly Reports Daily Data Report for September 2018 - Climate - Environment and Climate Change Canada

Too lazy to calculate dews but the airport is usually ~2C lower than NYC Laguardia and the downtown station is ~1C lower albeit with lower air temps than the airport station. 2018 was an exceptionally humid year for Southern Ontario, dews in Toronto were on par with NYC and Chicago.

Toronto is much more continental than Philly being so far from a warm ocean in summer.



Dew points imo are significantly lower in summer. 6 to 7F lower dewpoints is a lot in summer.

Imo Toronto winter climate is soo bad it can't overcome some "warm" summer temps to make it a worthwhile climate.



jan avg would be the second coldest month ever here. Far colder and less warm climate.

How many times did Toronto hit 70F/21C+ dew points in 2018?

Chicago/MDW hit it 45 times, while here in the far south suburbs closer to corn fields IKK hit it 58 times. For comparison sake, LGA NYC hit 70F dew points 40 days in 2018

Helping a neighbor clean up some tree branches that came down in the wind. Free Firewood for me. Waiting for the snow in 36hrs. Cloudy day today staying in the 20s.


Future Radar Loop. Snow for 12 hours in Philly? Rain points south of there. Watch the snow change to sleet/ice even up to New Hampshire. Ugh.
