The record low for May where I live is -7C or about 20F. The record low for September is -3C or about 25F.


I've seen temperatures just below freezing in May but almost never in September. Though I've seen snow flurries on the last day of September but I think the temperature was still a degree or two above freezing.


The record lows for July and August here are above freezing, and the record low for June is right at the freezing mark: 0C or 32F.


The record lows for April and November are quite a bit below 0F or -18C.


October's record low is -12C or about 10F.

What's the record low for Ottawa in April? Around -20 C?


Also, I'm sure Glacierx has some climate data on this. But I wonder what the record low for April in Canada is, something like -45 C or -50 C in Eureka?

Around that, but there is some discrepancy between stations. Experimental Farm is -21C, but the official station at the airport is only -16C.


For November, it's even greater. The farm is at -30C, and the airport is only -21C.


It's odd because the farm is surrounded by the city and further in. And the airport is further out and surrounded by fields and woods.

Not sure if it has the record for Canada but the record for April in Eureka is -48.9C.

That must be the Canadian record low for April. As I know it, the other Arctic and Yukon stations have never recorded a lower temperature.

Correct.

Quote:
Summit Camp, Greenland recorded -33.0 C (-27.4 F) on July 4th this year, which is the lowest temperature ever recorded in July in the Northern Hemisphere. I hope that the July low for GeoSummit, Greenland (another station at Summit Camp, which usually records lower temps) will be published soon, so this record may be lower.
That is what I meant. Thx.

White Mountain Summit CA recorded -0.2 F on June 6th, 2007, but its elevation is 14,246 ft.

That is probably the latest then.

Fahrenheit probably April 1942 I guess but during my life I'd guess the second week of March either in 2005 or 2006 (two whoopers).

Celsius, mid-May this year. -3C in fact. Crazy.

Not to mention in the rest of the world, outside of the US, "sub-zero" would refer to below 0C, so no wonder this thread is causing confusion...
The confusion has been noted, but as Alex said, after reading the first few posts, you'll notice we're talking about fahrenheit and referencing winter/early spring.

Like I said, I get the confusion because the title is a bit vague. But in all fairness way too many people comment on a thread without actually reading the first few pages to see what it's really about. A swift reading of the first couple of pages and people could've easily seen that the thread is talking about below 0 F and not below 0 C.


Plus, sub-0 F is a lot more rare and impressive.


If it's never been below 0 C in your climate I guess this thread doesn't apply to you in any regards lol. Maybe list the latest sub-10 C temperature?


Btw, latest freezing temp here in South FL was on March 3, 1980. It still astounds me so much that it's been freezing here in March, not to mention that same day had a high of 53 F (11.7 C) which would be impressive here in January, let alone March.
Exactly. I understand 0 C may be significant in some places, but that's not what the original intent of the thread was. Of course South FL is one of those places where it is significant, but is certainly isn't here or in Chicago, for example.
