Temperature
Normals
Lisbon has mild to warm, moderated temperatures, winters are very mild for its latitude, influence of the Portugal Current, a weak current by-product of the Gulf Stream, average highs during this season vary between 15 and 16 °C (59 and 61 °F). Lisbon has the mildest winter nights out of any major European city, ranging between 8 and 10 °C (46 and 50 °F). Summers are warm to hot, though due to the upwelling phenomena in the western coasts of its metropolitan area, maxima in summer has dramatic fluctuations depending on the location. Regions east of the Tagus Estuary usually average around 30 °C (86 °F) maxima in July and August, while western areas close to the coast, such as Cascais or Sintra, will usually average around 23–25 °C (73–77 °F) maxima, reaching as far as 21 °C (70 °F) in Cabo da Roca. Costa da Caparica does not have such strong upwelling conditions and is usually hotter in the summer than the aforementioned coasts. Summer nights are often independent on the location, averaging a comfortable 16–19 °C (61–66 °F).[13]

Extremes
Lisbon's location on the westernmost side of continental Europe makes it much less vulnerable to both heatwaves and coldwaves, though outbrakes of the Saharan Air Layer can sometimes push the temperatures above 40 °C (104 °F) as it happened as part of the 2018 European heat wave, skies were a shade of white due to the extreme concentrations of airborne dust particles. Temperatures in two of Lisbon's stations reached an all-time high of 44.0 °C (111.2 °F) on 4 August of that same year. The third station (Tapada da Ajuda) recorded 43.3 °C (109.9 °F).[14][15] The coldest temperatures ever recorded in the city were −1.5 °C (29.3 °F) on 15 January 1985[16] and −1.2 °C (29.8 °F) on 11 February 1956.[17]
In a normal year, the recorded maxima can go anywhere from 12–19 °C (54–66 °F) in the winter and 23–35 °C (73–95 °F) in the summer, and the minima from 3–14 °C (37–57 °F) in the winter and 16–24 °C (61–75 °F) in the summer. Temperatures behond these are usually considered irregular and limited to exceptional years. Lisbon is on the USDA hardiness zone 10b.[18]

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 which is therefore the greenest time of the year. 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 more than average rains but still avoiding a wet summer (>30 mm (1.2 in)). 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 calçada near shady areas.
Lisbon has on average 112 precipitation days a year of which around 30% is drizzle (below 1 mm (0.039 in)). The driest months, July and August, have on average two days of precipitation (4–6 mm (0.16–0.24 in) of which 50% is drizzle), and the wettest months, November and December, have on average 12–15 days of precipitation and around 127 mm (5.0 in).[19] December is the rainiest month of which half the days receive some form of precipitation. The average annual precipitation is 774 mm (30.5 in).[1]

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. This humidity also ads to its mildness but can also result in muggy conditions in the most humid winter days, especially in closed spaces with no air filtration. The air in the summer is otherwise dry, 60 to 65%, and is particularly variable, often going below 40% during the day and 70% at night.[13][20]
