Why not use meteorological days? my station count a day as 00:00-00:00. and if i use yesterday's min and max temperatures, the celsius values are rounded to nearest degree farenheit. the console shows 0C/32F and -2.2C/28F for yesterday, despite that it was 0.1C and -2.1C in reality. |

Okay. Is it not possible to change the day definition on it? And if not, why not just set back the time 5 hours? Or does it not matter too much to you? |

What is a "meteorological day"?

What is a "meteorological day"? It's how a day is counted in meterological statistics. The general standard, at least in Sweden and most of Europe seems to be 19:00 (20:00 on DST) seperating the days. So 21.00 today actually counts as tomorrow's meteorological day. |

That's . Midnight-1159 pm is more logical.

That's . Midnight-1159 pm is more logical. The point is to limit the number of nights yielding lows for two days instead of one. If a mild night is followed and preceded by a cold night, that mild night will completely disappear if you have a 00:00 divide, since the early morning before the mild night was colder, and the late evenimg after the mild night also was colder. 19:00 helps seperate the nights better since lows and highs don't tend to be centered around noon and midnight, but offset a bit. A low is usually before 07.00, and a high is usually before 19.00. The same can't be said if you switch it to 00:00 and 12:00 respectively. |

So what if the high occurs at midnight or at 3 PM? That's when it happened, it just displays the variability in weather. That's just dumb and nonsensical, I don't get why y'all have so much arbitrary bullshit in your weather stats.

Sounds like arbitrary shit to make the climate seem warmer than it is.
If I want to know the weather on January 23rd, I care what the weather was on THAT day, not the day before, not half the day, etc.

That's just dumb and nonsensical, I don't get why y'all have so much arbitrary bullshit in your weather stats. Unlikely things always happen eventually. The 19:00 system just makes it far less likely for it to happen. How often (barring polar latitudes) do midnight highs and noon lows happen? Regardless, it's far less common than 19:00 highs, and 07:00 lows. Sure, defining the day starting at 00:00 makes one sense, but I'd say it makes more sense to try to base the meteorological day on the diurnal temperature cycle than the sun's cycle. |

They're quite common in mid-latitude winters when a strong front is pushing through the area. Really not as uncommon as you make it out to be to get a morning high followed by a much colder afternoon. It doesn't matter what the usual pattern is, it will deviate from it every once in a while, and we shouldn't use arbitrary bullshit to try and make it happen less often.

You haven't the slightest clue of how many times BOM stations such as Oberon, Cabramurra, Thredbo and so forth record <0° C temperatures throughout the entire day, yet once next morning rises, it reaches ~1°-3° C...and so long as it was recorded before 9:00 AM, that is the supposed "maximum" for the day before, thereby skewing the averages in favour of warmth. Not to mention that the only reason for this fabled "reset" was for our 19th Century manual workers to get to their posts earlier and with less hassle, the lazy blighters... Absolute codswallop! |

It's . Even here in South FL we can have days like that, although of course not as common as further north. Baba acts like it only happens in places above the Arctic Circle lol. |

In Germany daily highs and lows are from 23:51 UTC (the day before) to 23:50 UTC. So it's actually 0:51 - 0:50 (the following day) in our Central European time.
Daily precipitation however is measured 05:51 - 05:50 UTC.
