The Weather in Barcelona in October

Updated: October 5, 2023

October in Barcelona features comfortable afternoons and early evenings with generally cool late nights and mornings.

As a retired meteorologist turned tour guide, I didn't expect that I would use my experience as a forecaster in my new career in tourism.

But here I am, finding myself answering more weather questions as a blogger than I ever did as a weatherman.

So, here are answers to some frequently asked questions about the weather in Barcelona in October.

How Hot Is Barcelona in October?

Afternoon high temperatures tend to be around 23-24 C (73-75 F) early in October but fall to 21-22 C (69-72 F) near the end of the month.

A few of the warmer afternoons, especially early in October, can reach near 27 C (80-81F).

The record high temperature in Barcelona during October is 30.6 C (87 F).

Late night and early lows tend to be near 16 C (60-61 F) early in October but cool to around 11-12 C (52-54 F) near the end of the month.

A few of the colder mornings, especially later in the month, can dip down near 7 C (45 F).

The record low temperature in Barcelona during October is 2.8 C (37 F).

Sun vs. Rain

October in Barcelona features, on average, about 14 sunny, 4 partly sunny, and 13 mostly cloudy days.

About 10 days this month record some rainfall, however, only 6 days will record at least 1 mm (0.04 inches).


The number of daylight hours continues to decrease rapidly this month from about 11.8 hours on the 1st, down to about 10.4 hours by the 31st.


The wind in Barcelona this month tends to be mostly light to gentle at 6-19 kph (4-12 mph) but occasionally can be moderate at 20-28 kph (13-18 mph).

Ocean and Beach

Ocean temperatures remain warm early in October when water temperatures are close to 22 C (72 F), however, temperatures fall to 19 C (66-67 F) near the end of this month.

What to Wear in Barcelona in October?

October brings fall weather to Barcelona, however, early in the month the afternoons can still be warm, and shorts and sandals may still work.

Thereafter, cooler weather prevails, especially at night and during the mornings, which will require a light jacket or windbreaker, long-sleeved shirts, and tops, plus a couple of sweaters will come in handy. 

Don’t forget sunglasses and some comfortable walking shoes! 

Things to Do in Barcelona in October

Although there will be some rainy days this month, the chance of a lot of rain is very small.

As such, this might be a good time to consider taking a pay-what-you-wish walking tour in Barcelona.

October is the month of Mercat de Mercats (Market of Markets), a 3-day fair with plenty of food, wine, and desserts to try.

Entry is free, but you might want to bring some money for food.

As the name implies, this is also the month of Oktoberfest, and you can expect a great event at Universe Square of Fira Barcelona Montjuïc.
