Weather Overview for Lisbon
When you are talking about weather, Lisbon has some of the mildest compared to any other European capital city. Despite being located on the Atlantic Ocean, the climate is similar to that of Mediterranean coastlines. Summer temperatures are warm and sometimes hot, while winters are mild and damp. Lisbon sees a lot of sunshine (over 3300 hrs per year) and about 100 days of rain a year.
The Atlantic Ocean strongly influences the weather in Lisbon, primarily as a consequence of the nearby flow of the Gulf stream. These currents ensure that the coastal city of Lisbon does not experience the extreme temperatures that can occur in central Portugal and Spain. While on average about 600 mm, or 24 inches, of rain falls annually in Lisbon, the precipitation is spread out over 100 days of the year, so there are rare days without at least some sunshine.
Like anywhere in the world, weather varies year on year in Lisbon and averages don’t tell the whole picture. Some summers can be much hotter than others, and some winters much wetter. The city doesn’t receive too much unusual weather but violent storms can occasionally roll in from the Atlantic Ocean meaning a few days of very windy and wet weather. Torrential downpours can occur and huge waves can batter the coastline.
Summers are generally reliable in Lisbon. You are likely to get warm temperatures and lots of sunshine. The breezes of the Atlantic ensure that temperatures don’t often get uncomfortably hot like many parts of the rest of Portugal. Temperatures are very agreeable at this time of year – generally varying between the high teens and high 20s. It can, however, get much hotter and temperatures in the mid-30s are not uncommon especially when there is no cooling sea breeze. July in the summer can also boast that it has the most hours of sunshine: 360. For July and August there are at least 27 days where the temperature climbs above 30°C. The highest recorded temperature ever for those months reached over 41°C. Sea temperatures rise to 20°C by September and are only a degree or two less in June, July, and August.
Summers are very comfortable despite the warm weather. Morning and evening relative humidity remains fairly constant at about 80-38% in the mornings and 48-54% at night. The dew point remains a comfortable 14°C throughout June, July and August. With breezes blowing in the evenings and mornings at 10 mph, this further lessens the effect of any high temperatures.
Rainfall is very low in summer. June has more than twice as much rain as July and August combined, but still only averages 17mm or less than an inch. July is the driest month of the year and August a close second. Each average 5mm of rain at most. September sees a little more rain – about 20-25mm; still very dry compared to the rest of the months of the year.
Autumn is another good time to visit Lisbon, with very pleasant temperatures most of the time. September is really a continuation of summer and you still can enjoy July and August temperatures with sunny days and highs that normally reach 22°C. Lows only drop on average 1 degree from August to 17°C. By October though the change in seasons can be felt. The number of days with highs above 26°C falls from 18 days in September to only 4 in October. October daily high averages drop to 22°C, and the overall daily average drops to 17°C. Lows in October reach 14°C, and by November nighttime lows are at 11°C.
Rainfall begins to build throughout the autumn. September sees just 25mm of rain on average, but by November this has crept up to over 107mm. The number of rainy days too in this time period goes from 4 days a month in September to 12 days a month in November. Thunderstorms become more common as Autumn progresses into Winter. November and December are the wettest months of the year.
Relative humidity remains about the same for Autumn though the dew point drops by a few degrees. You will see a few more foggy days by the end of the season and of course the hours of daylight start to fall from almost 13 hours in September to just 10 hours in November.
The sea temperature falls about a degree per month throughout the autumn, as does the UV index.
Winters are mild in Lisbon and the temperate climate in comparison to most winter destinations ensure a pleasant holiday break from the dreariness of most European capitals during this season. The average low drops to around 8°C by January and then gradually climbs to an average low of over 10°C by March. The lowest temperature ever recorded in the last 30 years in Lisbon was 0.4°C. The average daily high starts off in November at around 14°C, dropping to an average of 11°C in January but then back up to 14°C again by March. Snow showers fall on occasion but usually in the form of a light dusting of less than an inch, and it usually melts quickly.
Winter is the wet time in Lisbon. The dampest periods occur from November to February, and these months see up to 115mm of rain on average. Winter can often be misty and drizzly and windy, and can also be a time for storms that roll in off the Atlantic. On average it will rain three days during the month from November through February but by March the average drops to one day in the month. Expect thunderstorms once a month. The wind blows strongest in February and March. The relatively few wet days makes the sunny winter’s days and reasonable temperatures seem very pleasant indeed.
Spring is an agreeable time in Lisbon with average temperatures by May creeping up to the 17°C mark with daily highs reaching 21°C and above. Sea temperatures creep up about a degree a month too and by May reach 17°C. In spring, you get around 13-14 hours of sunlight and 8-9 hours of sunshine. By the end of May the sun is rising around 6 AM and setting around 9 PM.
Rainfall is moderate in spring. In April you can expect to see about 12 days with some rain but by May this drops to nine. April rainfall averages 64mm and this drops to 55mm by May. Rainfall dries quickly with the sunny days and warmer temperatures.
With a dew point of between 8-10 in the spring you feel comfortable. About half the month you will experience some fog but it will not last all day. You will see some fog about half the days of the month. Haze that may obscure the normally brilliant sunny days happens 1-2 days at most. Blowing sand or dust occurs 2-4 days each month and wind speeds average around 18kmp.
