To see the daily range of temperatures have a look at the temperature max / min chart below. Precipitation: 0.00". The percentage of time spent in various temperature bands. The percentage of days in which various types of precipitation are observed, excluding trace quantities: rain alone, snow alone, and mixed (both rain and snow fell in the same day). Showing:All Year January February March April May June July August September October November December. The solar day over the course of the year 2020. The best month to swim in the sea is in September when the average sea temperature is 19.9°C (68°F). Lisbon is located near a large body of water (e.g., ocean, sea, or large lake). Temperature 23 °C 73 °F. In 2020, the shortest day is
This section reports on the wide-area average surface temperature of that water. The average growing degree days accumulated over the course of the year, with 25th to 75th and 10th to 90th percentile bands. The number of hours during which the Sun is visible (black line). 72.5. To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day of the year. Cloud Cover: 0.0%. Low Temperature 17.6 °C 64 °F. The length of the day in Lisbon varies significantly over the course of the year. Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. Mean Temp: 63 °F. However, it can get much hotter with temperatures over 86ºF (30ºC) and lows of 62ºF (17ºC). We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year. High Temperature 26.5 °C 80 °F. Sea Temperature 19.9 °C 68 °F. In summer, the warmest month is July with average temperatures of 74ºF (24ºC). To characterize how pleasant the weather is in Lisbon throughout the year, we compute two travel scores.
We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series.
58.8. Shortwave radiation includes visible light and ultraviolet radiation. The daily average water temperature (purple line), with 25th to 75th and 10th to 90th percentile bands. Among wet days, we distinguish between those that experience Dew Point: 53 °F. The average rainfall (solid line) accumulated over the course of a sliding 31-day period centered on the day in question, with 25th to 75th and 10th to 90th percentile bands. The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray. For each station, the records are corrected for the elevation difference between that station and Lisbon according to the The percentage of hours in which the mean wind direction is from each of the four cardinal wind directions, excluding hours in which the mean wind speed is less than
The thin dotted line is the corresponding average liquid-equivalent snowfall. The transitions to and from daylight saving time are indicated by the 'DST' labels. Weather data is prone to errors, outages, and other defects. The average hourly temperature, color coded into bands. There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Lisbon. The best time to visit Lisbon Low Temp: 47 °F. The estimated value at Lisbon is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Lisbon and a given station. The shaded overlays indicate night and civil twilight. All Year Climate & Weather Averages in Lisbon. Temperatures in Lisbon are sufficiently warm year round that it is not entirely meaningful to discuss the growing season in these terms.
