10 * [26.03 + 11.44 - 3.2]
= 342.7

10 * [26.03 + 11.44 - 3.2] = 342.7 Come on, why do you people often forget to subtract the latitude?  343 – 38 is your real result. |

Come on, why do you people often forget to subtract the latitude? 343 – 38 is your real result. Because it’s not in the formula... It also makes no difference for many people. IMO, if anything it should be added because I think long days and late sunsets feel very summery and certainly moreso than short days. |

The main factor here is the sun strength; a stronger sun will make it feel more summery. Also, I only mentioned daylight length in relation to fraudulent sunshine hours being added into the equation. Since the days are much longer at higher latitudes, there is more time for extra "sunshine" to register (when it's really just extra daylight, thereby making it look "sunnier")—Scandinavian and other Northern European climates, especially, have cloudy crummers in reality (e.g. London with only ~ 50% possible sunshine). |

So almost identical to London's 1981-2010 summer index. Which is pretty absurd. Yes, you're right, that, of course, is absurd. If you had a sincere desire to compare something you would either use the Umea 1981-2010 averages and compare them with the London 1981-2010 averages or you would compare the 2002-18 averages for both cities. Right now you are comparing pears to apples and of course you get a ridiculous result in response. Your desire to show your coastal Central-North Sweden brighter than it is is desperate. In this sense, you can be like an inverted Hiromant, whose great fetish was to instill in this forum participants that his climate is like Murmansk's. But keep working and by year 4020 you will achieve that the Umea's 'summer index' is similar to the current Malaga summer index. Good luck. |

I didn't attempt to compare Umeå's climate to London's climate. I explicitly compared Umeå's stats for 2002-2018 to London's stats 1981-2010. I just compared a summer averaging 3'C warmer highs to a summer averaging a few percent extra sunshine and longer daylight. I could have compared Umeå 1981-2010 to London's 1981-2010 if I really wanted to specifically compare Umeå's climate to London's, and wanted it enough to spend the additional time compiling the averages from excel documents instead of just looking at the already made weatherbox. But my point wasn't to compare Umeå and London. Nor was it to make Umeå seem "brighter than it is" or else I wouldn't have downplayed the result so much.

Turku 91-19, sunshine 2001-2016
Average high: (19.7+23.0+21.4)÷3 = 21.4
Sunshine: (274+303+245)÷67 = 12.3
Rainy days (≥1mm): (8+9+10)÷8 = 3.4
303 or 243 if you do it Analdick Ghayler style.

I agree with that 2nd part, sunshine percent is more useful. However, I think longer days have far more of an impact on how “summery” it feels than stronger sun. For example, I’d find Fairbanks to feel more summery than San Francisco due to the much longer days even though temps are similar. |
