Temperature
=Normals=
Lisbon has mild to warm, moderated temperatures. Winters are mild especially for its latitude with average daytime temperatures between {{convert|15|and|16|C}} and nighttime lows between {{convert|8|and|10|C}}. Summers are warm to hot, but due to the upwelling phenomena in the western coasts of its metropolitan area, maxima in summer fluctuates considerably depending on the location. Regions across the Tagus Estuary, for example, typically average around {{convert|30|C}} maxima in July and August, while areas west of the city and close to the coast, such as Cascais or Sintra, will usually average around {{convert|23|-|25|C}} maxima, reaching as low as {{convert|21|C}} in Cabo da Roca. Costa da Caparica is an exception to this rule as it is far less exposed to the cooler ocean currents and is therefore warmer in the summer. Nighttime lows during summer are often independent on the location, generally around {{convert|16|-|19|C}}, but the typical urban heat island phenomenon felt by the capital can increase these lows significantly compared to rural areas of its district.{{cite web |title=ClimaAlterações Climáticas em Portugal |url=http://portaldoclima.pt/pt/ |publisher=IPMA |access-date=30 January 2021}}

In a normal year, the recorded maxima can go anywhere from {{convert|12|-|19|C}} in the winter and {{convert|23|-|35|C}} in the summer, and the minima from {{convert|3|-|13|C}} in the winter and {{convert|16|-|24|C}} in the summer.

Precipitation
Lisbon can be described both as a moist and a dry city depending on the season of the year. Precipitation is most common in Autumn and Winter. Summers in Lisbon tend to be very dry due to the Azores High though exceptions happen and low-pressure areas can come into play bringing much more rainfall than normal but still avoiding a wet summer (>{{convert|30|mm|abbr=on}}). Foggy mornings are also common in the summer, especially in coastal areas and can bring drizzle which can sometimes be observed early in the day in wet roads and calçadas.
Lisbon has on average 112 precipitation days a year of which around 30% is drizzle (below {{convert|1|mm|abbr=on}}). The driest months, July and August, have on average two days of precipitation ({{convert|4|-|6|mm|abbr=on}} of which 50% is drizzle), and the wettest months, November and December, have on average 12–15 days of precipitation and around {{convert|127|mm|abbr=on}}. December is the rainiest month of which half the days receive some form of precipitation. The average annual rainfall is {{convert|774|mm|abbr=on}}.

Humidity
In the same way precipitation varies greatly from month to month, the average relative humidity also experiences considerable seasonal changes. Lisbon has very humid winters, averaging 78-80% humidity. The air in the summer is otherwise dry, 60 to 65%, and is particularly variable, often going below 40% during the day and surpassing 70% at night.

Sunshine
Lisbon is a sunny city, in fact, it is one of the sunniest capital cities in mainland Europe and one of the sunniest overall places in southern Europe, with more than 2,800 yearly sunshine hours despite the relatively high yearly precipitation. Sunshine and precipitation stack up oppositely with the dullest month being also the rainiest (December) which has around 140-150 total hours. Despite July having the most sun hours, August is on average the sunniest month with around 80% chance of direct sunlight hitting the ground.
In the Lisbon area, sunshine hours reach their maximum value in the southwestern Setúbal Peninsula (near Cabo Espichel), and their lowest in the Sintra Mountains and parts of the northwest District.{{cite web |title=Solar prospecting tool for fast and reliable project pre-feasibility |url=https://apps.solargis.com/prospect/map?show-registration=1 |publisher=SolarGis |access-date=30 January 2021}}

Daylight
Due to its southern position in Europe, Lisbon has a rather optimal number of hours of daylight. Winter days are not as short as in the northern part of the continent and summers have at least 9 hours of nighttime. The average duration of daylight in the wintertime is 10.3 hours{{cite web |title=Lisbon climate guide |url=https://www.weather2travel.com/portugal/lisbon/climate/ |publisher=weather2travel.com |access-date=30 January 2021}} (for comparison: London{{Cite web|url=http://www.weather2travel.com/climate-guides/united-kingdom/london.php|title = London Climate Guide: Monthly Weather, England}} or Moscow{{Cite web|url=http://www.weather2travel.com/climate-guides/russia-europe/moscow.php|title=Moscow Climate Guide: Monthly Weather, Russia (Europe)}} or Warsaw{{Cite web|url=http://www.weather2travel.com/climate-guides/poland/warsaw.php|title = Warsaw Climate Guide: Monthly Weather, Poland}} have about 8 hours).
Wind
Lisbon is generally still, though it can become quite windy in occasional Atlantic storms, accompanied by rain. The average wind speed depends largely on the area. Tapada da Ajuda has almost no sign of wind, other areas such as Gago Coutinho, near the airport, get double that wind speed. The District of Lisbon, especially the west, is one of Portugal's windiest zones. Cabo da Roca has registered wind gusts of up to {{convert|169|km/h|abbr=on}}.{{cite web |title=IPMA estima ventos entre 180 e 190km/hora durante a tempestade Leslie |url=https://observador.pt/2018/10/16/ipma-estima-ventos-entre-180-e-190km-hora-durante-a-tempestade-leslie/ |publisher=Observador |access-date=30 January 2021}}
