The summer weather in Geneva is very pleasant. It’s warm enough that you can walk around in thin t-shirts and comfy shorts, but it’s not so hot that you will be sweating bullets just by spending the day outside. Plus, even if you end up sweating bullets because of the heat, you can always just jump in that massive lake to cool down a bit!
Geneva is surrounded by mountains so it has a rather mild climate in the summer. The average daily highs are at a comfortable 26°C, but it is worth noting that temperatures sometimes exceed 30°C, especially in July. The average lows during the summer are at around 10°C, so you might still need a hoodie or a lightweight jacket for evening outings.
Another thing to note is that Geneva is a rainy city and you should expect about a week of rain per month in the summer as well. The summer months actually have more precipitation than the winter and spring months, so it’s smart to keep an umbrella in your bag, just in case.
