If you are looking for good weather, then the best time to visit Barcelona is during May, June and July. That is when the weather is hot and at its most pleasant. It becomes hotter in August, but it also becomes very humid, which some people do not enjoy. People that are not used to hot weather may prefer to visit in October and November because the weather is still warm, but you will see far more clouds in the sky and there is a little more rain.

How hot is it in Barcelona? The hottest months are May, June, July, August, September and October, the hottest month is usually August, where temperatures typically reach 30 degrees Celsius / 86 degrees Fahrenheit.

The coldest months are November, December, January and February. The coldest month is typically January, where temperatures fall as low as 13 degrees Celsius/ 55 degrees Fahrenheit.

Most people will tell you that how hot it is depends on the amount of sunshine your locations receives, for example, there are many people from northern Europe that claim Winter is too hot for them after the sun has been out just four hours. Others describe the winter weather as "Nippy" at most. Winter weather is usually the most unpredictable. Some winters are mild, some are blustery and very rainy, and some are even snowy in January.

The weather can become blisteringly hot, especially when there are fewer clouds in the sky. Plus, the wind and rain can sometimes go missing for days. Beware of heat stroke and sunburn. Also, Barcelona’s pickpockets come out on the sunniest days because tourists have fewer clothes on (ergo fewer zippered coats hiding wallets), and because people tend to become a little sleepy in Spain when the sun is blazing.

The police are typically not interested in tourists that are pick pocketed, so don’t expect much help from them. Also, beware of fake undercover policemen, and people asking for donations. Read online theft stories to get an idea of the latest scams. Barcelona is a safe city compared to the rest of Europe, but every oasis has its mosquitoes.

Most weather websites will give you a rough idea of what the weather will be like within the next two weeks, but that is usually as far as they go. However, you may be pleased to learn that the weather in Barcelona is usually the same year-after-year.
