I makes me a bit sad that I've moved from Ottawa to Toronto, cutting my time in the "freezing" from 3 months to half that.

Seeing a 3D stacking over the years (maybe a moving average) would be interesting, to see how much things have warmed since I was a kid.

Overall, that's a neat page!

I like the way that this site lets you compare "pleasantness" of climates, e.g. humidity + temperature etc year round. This makes me wonder, where in the world has the objectively "best" climate? Comfortable or warm all year round, not too humid, not too windy, lots of sun.

I'm gonna advocate Tenerife (my island) since it would be amazing to have more HNers around :) https://weatherspark.com/y/147639/Average-Weather-at-Tenerif... Doesn't seem to get much better according to weatherspark :)

It's like Hawaii, but after adding back in some "cool" temperatures.

Cool project! Would be interesting to see a metric on "average temperature change since 1960" to see which places have been hit hardest by climate change Saying the planet has increased in temperature by 1.5 degree doesn't mean much - but if a city has increased in temperature by 5 degrees, I think that makes it feel much more "real"

I'm starting to develop a laundry list of problems that I perceive with the presentation of climate change science.

People keep giving the temperature anomaly, as if there was something fundamental about the baseline temperature. This is kind of nuts, from a simple layman perspective. Tell me what the temperature was before and tell me the temperature after.

I also wonder if the US would have taken action by now if the numbers had been presented in Fahrenheit. Living in the US, I'm totally fine with Celsius... for science. I'm not okay with it for evaluating comfort. I have no idea how a Celsius temperature feels. My lizard brain knows Fahrenheit. 1.5 degree increase doesn't really sound bad. 2.7 does.

These climate blankets would be crazy useful for climate change. Show the complete decimation of comfortable temperatures (mainly in the tropics), and the point will be much better taken.

From the point of view of someone living in northern North America, this is quite warmth-biased, with * temperatures below "very cold" being called "freezing" (huh? mere freezing is not considered terribly cold in much of North America, where "very cold" would likely restricted for T * "comfortable" extending into times of year when the heat and humidity bothers most locals * the favourable tourist times being centre…

I was the one who devised those labels and it was hard to come up with the words to describe the temperature ranges (we also report the raw temperature range for each category, so you can remap the words as you please). I did my best, looking at a variety of sources and relying on my own experience, having lived in a variety of climates myself.

The one that I was quite confident would be widely agreed upon was "freezing", since it has such a literal meaning of a temperature where water freezes.

But as with all things weather, its complicated. Personal preference, clothing choices, activities, all contribute.

But we hope the fingerprints are nevertheless and informative and interesting way to explore the average weather!

It'd be cool to be able to show the most similar fingerprints for any location. I.e. I want to see which locations have similar climate to city X.

On each annual report page, at the bottom of the Temperature section, just before the "Compare X to another city" section there's a paragraph that for NYC reads: "Gedzhukh, Russia (5,672 miles away) and Yatsuomachi-higashikumisaka, Japan (6,752 miles) are the far-away foreign places with temperatures most similar to New York City (view comparison)." - it's a little hard to find, but there's a lot of info competing for attention, not to mention the ads :-/

It's a little weird looking at e.g., Central Africa and seeing no maps. Maybe they chose locations based on population? Either way, would be nice to fix this, as there are places with data available.

We show temperature fingerprints for all the weather stations in our network, you can find links to the data sources here: https://weatherspark.com/y/147186/Average-Weather-at-John-F....

Earlier quoted context omitted.

Every page & image (they’re all embedded SVGs) is generated from scratch using raw data on every request - with the number of languages and units supported it gets quite unwieldy when pre-generating (we had a mediocre experience w that on statisticalatlas.com). In order to render in a timely fashion the sections & graphs are rendered in parallel on a decent sized instance.

A middle ground could just be adding some caching?

Typically 80-90% of our traffic is search engine bots crawling the site, which is not very amenable to caching. So even if we cached all user traffic the overall load wouldn't move much.

That said, it might make sense to cache to protect against load spikes on specific pages, but unfortunately those don't happen a whole lot.

Very cool. Reiterate other's comments that mouse-over a fingerprint showing a hover would be great. When clicking a fingerprint, the next page should prominently show the fingerprint, burying it in the page, especially when it isn't obviously a long scroll page, made it hard to find. Please consider inverting "Spring" etc for Southern Hemisphere, as currently it has a _very_ Northern centric view of the world. Thanks…

Spring in NYC is Mar-May: https://weatherspark.com/s/23912/0/Average-Spring-Weather-in...

Spring in Sydney is Sep-Nov: https://weatherspark.com/s/144544/0/Average-Spring-Weather-i...

But maybe you meant something else?

Yes I meant when comparing, per below, Sydney is 20-30 degrees celcius in "Winter". Not sure why that view defaults with the seasonal labels.
