What is the significance of mentioning 23-degree weather and people looking like baked lobsters in London?

The significance of mentioning 23-degree weather and people looking like baked lobsters in London is the rarity of such weather in the city, and the people's unpreparedness for it. London is known for its typically cool and damp climate, and temperatures reaching 23 degrees Celsius (73.4 Fahrenheit) are considered quite warm by local standards. When such temperatures occur, many people in London, particularly tourists, are not prepared for the heat and are likely to get sunburnt, hence the reference to people looking like baked lobsters.

This cultural observation highlights the importance of understanding local customs and weather patterns when traveling to a new place. It also serves as a reminder of the impact of climate change on the world's weather patterns, with even cities like London experiencing uncharacteristically warm weather. In recent years, London has seen several heatwaves, with temperatures reaching up to 36 degrees Celsius (96.8 Fahrenheit) in some parts of the city.
