This may seem dead obvious, but it’s surprising how many authors don’t get it. The weather around the world is different. And not only that, people’s perceptions of it differ too.
Every year the Americans laugh at me when I start wearing two sweaters and wooly socks as soon as the temperature drops below 21C (70F). Most of them are still in t-shirts and shorts. But I live in a temperate climate, where hot, dry weather is common and it never snows. People who live in areas with snow for several months of the year, would not appreciate a nice summer here, where the temperature may stay over 100F for a week or ten days straight.
So when you are writing about the weather, either use terms that people can make fit their own preconceptions, “it was cold but sunny”, or be sure you have your facts correct. Remember blogs and Wikipedia aren’t always accurate, and are tainted by personal bias. Someone from far northern Australia complaining about the heat probably means 100% humidity and 40C (104F) but to someone from the central Australian desert, 40C is hardly even midsummer weather, but the humidity is very, very low. Anyone from Ireland however, would be in hospital from heat exhaustion about then. Their temperatures seldom rise about the mid80s.
