Some places have stations in the middle of their UHI, not reflecting the climate of most of the people living in there, and other places have stations outside the UHI, not reflecting the town's climate either. Because parks and flat surfaces often tend to be surrounded by higher ground, many weather stations end up in microclimates with cooler nights. So if you could decide where to put a weather station to fairly represent the climate of the average person in the town, where would you put it? Here's one that I've come up with for Umeå. It's on the west, more housey side of Umeå, and don't quote me on this but I believe more people live in the eastern more dense apartmenty side, so in that way it isn't ideal (although since Umeå is only like 10km across, it doesn't really matter much). I chose this spot because the eastern half didn't have a park that wasn't either too UHI or surrounded by higher terrain.    Here's an alternative:  It's got a very good geographical placement in terms of being close to the average distance to the city center as well as being on the side where more people live.  It's not perfectly flat terrain though which is a drawback.  And this is where our airport station is. I am not sure on the exact position. I think it might be on the red marker  I feel like frost hollow is an exaggeration, but it really does get significantly colder nights than almost anywhere else in the city.  Also, if you want the same topography map I'm using, here's the link in metric: en-nz.topographic-map.com/ and here's with the imperial system: en-us.topographic-map.com/ |

I'm more pleased with the location I came up with for Stockholm. Its current station is, even though I don't like to admit it, in a pretty ridiculous location. It's right in the core of a pretty dense central borough.   On top of that, it's also located in an elevated location!  So it definitely doesn't reflect the climate of the majority of the people in Stockholm. My suggestion for a fair station would be here:  It's in one of the most populated boroughs, and it's at a very typical distance from the center.  Stockholm is pretty hilly, and this is one of the few fields in the entire city that isn't on low ground. It's surrounded by four smaller hills, but it's also surrounded by lower ground as well, so it should have a pretty average topographic placement.  |

Angler's Property AWSSituated astride a most splendorous swathe of land, Angler's property is fairly representative of the Eucumbene countryside; 1,282 m AMSL; 35° 59' 52.08" S:  Say hello! Notice the gently undulating country—typical of the Eucumbene regional (picture taken April 2019):

Where exactly do you mean? On the pavement? On the bridge? Either way, I'm pretty sure it's going to be warmer on any of these parks located on hills. Btw, why are all of Turku's parks on hills instead of in valleys like they are here lol?  |

Pavement probably.
The top left hill is a former leper hospital, Vartiovuori was ja slum, the centre hill was an old pre-Christian fortress ruin, and the Urheilupuisto hill used to be a treeless barren hill and lookout.

We already have one by the University here, which is right across the river from downtown. That's about as good a location as I can think of.

I don't know Aachen well enough yet, so I'll Frankfurt.
The UHI station is quite appropriate at the edge of a park just outside the inner city.
Though I would put it farther away from that building to the east and ideally farther away from a footpath.
The airport station already is very good. No need to change anything.

New question: If you were given a choice to place out only two weather stations in your village/town/metro (or three if your metro area has >1m people, or one if you live in a <10k town/village), where would you place them? I'd put one station in the middle of the city center, on a relatively small park or yard, and one in a large open area right outside the city border, preferably at a similar distance to the sea as most of the city. Either of these three stations would be my pick for the UHI station  And here's a city-scale overview including the three alternatives for a non-UHI stations. Non-UHI station1 is probably the best bet of the three. I also added two "Slight UHI" stations where I'd place a station if I could only have one station to represent the city.  |

If I could only place 2 weather stations in London, I'd put one at Heathrow and the other in a small garden square like Eaton Square.

Sheffield has a lot of elevated areas as it's in a hilly location. The North East side is very low and flat and tends to be warmer; the highest hills to the south-west are probably not much milder than Buxton. I can get an idea of the climate of those areas by looking at PWS on weather underground, but not as accurate as official stations of course.

The main station is on the CSU campus which is a good location. Gets slight UHI but it represents Fort Collins very well. There’s also a more recent station 4 miles east. This one is by a wetland area on the eastern side of the city. It’s drier and slightly more continental, also seems representative of an area farther out on the plains. I wouldn’t move either station and it wouldn’t be worth it to add another city station. However, I might put one out by the hogback or on the reservoir to see the impact of being a bit higher and closer to the mountains. In red are potential additional stations  |

The current locations are fine in that they capture the best contrast. The airport station records more extreme temps, while the downtown station records milder temps.

There is decent sized piece of unused land next to the Renmark Clowncil chambers which I think would be an ideal spot for an AWS. Reasonably central to the population and would certainly be more representative of the local climate where the population actually live than the damn frost hollow airport.  Now, the Palm Stump is a dead tree stump with a palm bush on it near the convergence of the Murray River and a major boating inlet. This stump should have an AWS mounted on it to study the effects of hurricane force southerlies on the local bird population, and provide up to the minute wind data for boaters. Also would be fun to see how temps and DPs are out on the water compared to land. Locations of both stations  |

1. Park Square in the city centre (34m asl). This would be a good representation of the UHI. ![]()  2. The southern part of Roundhay Park (104m asl). Located in the suburb of Roundhay, this would be fairly representative of where most people in the city actually live.  |

So is this the location where Stockholm's Wikipedia averages are from? That's ridiculous indeed.

It's ridiculous in comparison to how most cities tend to place their stations. However, it's very reasonable for describing the climate of 5-10% of Sweden's total population. |

Does anyone have the climate averages for Stockholm Bromma? I have 1991-2018 data for temps (I used the same stations for prec and sun for both weatherboxes)   Considering the highs don't differ in any meaningful way, and it's only the lows that are milder (by 1.5'C annually), I feel it's reasonable to use the station. I mean an airport down by some low-lying fields in the edge of the city is expected to be a fair bit cooler at night than almost anywhere else in the city. There are very many examples of UHI stations averaging highs 1'C warmer than the other non-UHI stations, and 1.5'C for the lows is hardly anything noteworthy for a city with 2m people |
