Lisbon Weather & climate

Use current conditions together with recent historical climate signals. Placeivo keeps live weather separate from annual context so a single day is never presented as the city climate.

How to read it

Current weather is not the same as climate

The live temperature, precipitation and wind readings describe conditions around the latest check. They are useful for immediate orientation, but they should not be treated as a description of a typical year in Lisbon.

For that reason, Placeivo keeps recent annual climate indicators in a separate section. Looking at both layers helps distinguish “what is happening now” from “what recent historical conditions looked like.” The page does not turn those signals into a single comfort or liveability score.

Recent context

Historical context for Lisbon

These values describe a recent historical period rather than the current moment. They are shown separately to prevent live and historical observations being mixed together.

Seasonality

Lisbon monthly climate pattern, 2021–2025

These month-level values aggregate 5 complete calendar years from the same Open-Meteo archive used for Placeivo's annual climate evidence. Temperature is the mean of daily mean temperatures, precipitation is the average monthly total across that period, and wind is the mean of daily maximum wind speeds.

Evidence interpretation

What the latest Lisbon evidence says

At the latest recorded check, Lisbon was 20.7 °C, with 0.0 mm of precipitation and wind speed of 22.1 km/h. Those values describe the latest observation only.

The stored 2025 climate context reports a mean temperature of 17.62 °C, total precipitation of 975.1 mm and mean daily maximum wind speed of 18.07 km/h.

The latest temperature is 3.1 °C above the 2025 annual mean. This is a snapshot-to-annual comparison, not evidence that the current weather is unusual for the date or season.

Evidence & methodology

Where these weather & climate figures come from

Placeivo keeps source attribution, the date represented by the observation, the latest verification check and confidence metadata separate. This makes it possible to inspect the evidence instead of relying on an unexplained score.
