The day in Barcelona will be marked by a high probability of precipitation and a virtually overcast sky. Temperatures will range from a maximum of 27.5 degrees to a minimum of 21.3 degrees.
The 28th of September arrives in Barcelona with a forecast of 55% chance of rain throughout the day, according to meteorological data. Cloud cover will be nearly total: 99% during daylight hours and 98% at night, meaning the sun will have few opportunities to peek through.
Temperatures will fluctuate between a maximum of 27.5 degrees and a minimum of 21.3 degrees, mild values for this time of year. The UV index will reach a level of 2, considered low, which reduces the risk of sunburn despite the radiation still being present.
The wind will blow with gusts that could reach 13 kilometres per hour during the day and drop to 11.1 kilometres per hour at night. These are moderate gusts that should not cause significant disruptions to mobility or outdoor activities.
The combination of rain and overcast skies invites residents of Barcelona to take umbrellas or raincoats if they plan to go out. It is also advisable to plan journeys with some margin, as the rain may slow down traffic during peak hours and affect usual routes.
September and October are, in fact, the rainiest months of the year in the city, according to the State Meteorological Agency (Aemet). The minimum temperature in Barcelona usually falls below zero degrees between December and January, while the maximum hovers around 30 degrees in July and August.
Snow is a rare phenomenon in the Catalan capital: there are on average no more than 10 days a year with snow. For this Monday, in any case, the snow level will not be a factor to consider.
The climate of Barcelona combines continental Mediterranean, with mild winters and dry, warm summers, and humid subtropical in the northern area, where precipitation is spread throughout the year. This variety explains why the city can shift from sunny days to episodes of persistent rain in just a few hours.
For those who need to be outside, the recommendation is to check the forecast throughout the day, as the chance of rain may vary. Meteorological authorities have not issued alerts for adverse phenomena for the day.
