Germans tell me: 'But you come from a tropical country, you must be used to this'. And my answer, like Isildur's, is 'No'. Tropical localities have relatively minor changes in temperature across the year, but within the same country we may have areas that are below freezing all year round with others that are always ca. 30°C on average. I lived in an area with an annual average temperature 20°C temperature, which for me is close to perfect. In rare occasions it got up to 30 and down near 10, but that was unusual and never for more than a few hours.
Now here where I live nowadays we have got like 30°C (peak was 37°C or so) for a week or so, even late in the night and that takes away any will to do anything in my free time (expect even more decrease in my activity). To make things worse, even though I leave the windows open in the night, when temperature goes down to a still uncomfortable, but more manageable, 25°C, I feel the building I inhabit irradiates all the heat it received during the day, during the night hours and in my flat I feel no noticeable change in temperature. I was not a sweaty person but I think I have sweat more this last week that during the rest of my lifetime in my home country. It is insane. After being more than one year here in Germany I can tell that I liked more last summer, which for many Germans I have talked with, was ugly and say it was no real Summer. And you know what. I prefer fake summer, like I prefer fake boobs. I have experienced high, almost 40 °C temperatures before, but for a couple of hours/day not the freaking 24 h. Because seriously, I feel German infrastructure does nice to keep heat, but terrible to get rid of the excess. They are like greenhouses. Even at 4 am you can touch the walls and they feel warm.
Although not always, surprisingly often both buses and trains have their air conditioned turned off, so entering them is like going inside a smelly sauna, their windows can be opened but just few cm. Yes, In my country buses usually lack real air conditioned but their windows can be opened enough to let a boar jump thru them and that allows air to circulate freely. In Germany houses and buildings rarely have air conditioned. I'll have to get a fan or something, because this crappy weather will continue for quite some time, I am sweating off my own weight daily and I have no idea how to cool down my brain and prostate. Oh fake summer, I miss you. I won't say I miss winter tho. I don't like too cold stuff either. Best wetter is tropical cloud forest weather, 1000-1500 masl, hands down
