The figure below shows you a compact characterization of the hourly average spring temperatures. The horizontal axis is the day, the vertical axis is the hour of the day, and the color is the average temperature for that hour and day. CloudsThe spring in Monaco experiences essentially constant cloud cover, with the percentage of time that the sky is overcast or mostly cloudy remaining about 43% throughout the season. The highest chance of overcast or mostly cloudy conditions is 47% on May 7. The clearest day of the spring is May 31, with clear, mostly clear, or partly cloudy conditions 61% of the time. For reference, on October 20, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 48%, while on July 20, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 82%. PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Monaco, the chance of a wet day over the course of the spring is essentially constant, remaining around 18% throughout. For reference, the year's highest daily chance of a wet day is 25% on November 17, and its lowest chance is 6% on July 14. RainfallTo show variation within the season and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day. The average sliding 31-day rainfall during the spring in Monaco is gradually decreasing, starting the season at 1.5 inches, when it rarely exceeds 3.4 inches or falls below 0.1 inches, and ending the season at 1.2 inches, when it rarely exceeds 2.6 inches or falls below 0.2 inches. The highest average 31-day accumulation is 2.0 inches on April 24. SunOver the course of the spring in Monaco, the length of the day is very rapidly increasing. From the start to the end of the season, the length of the day increases by 4 hours, 0 minutes, implying an average daily increase of 2 minutes, 38 seconds, and weekly increase of 18 minutes, 28 seconds. The shortest day of the spring is March 1, with 11 hours, 13 minutes of daylight and the longest day is May 31, with 15 hours, 13 minutes of daylight. The latest sunrise of the spring in Monaco is 7:13 AM on March 31 and the earliest sunrise is 1 hour, 21 minutes earlier at 5:51 AM on May 31. The earliest sunset is 6:19 PM on March 1 and the latest sunset is 2 hours, 45 minutes later at 9:04 PM on May 31. Daylight saving time (DST) ends at 3:00 AM on March 31, 2024, shifting sunrise and sunset to be an hour earlier. For reference, on June 20, the longest day of the year, the Sun rises at 5:48 AM and sets 15 hours, 27 minutes later, at 9:15 PM, while on December 21, the shortest day of the year, it rises at 8:01 AM and sets 8 hours, 55 minutes later, at 4:56 PM. The figure below presents a compact representation of the sun's elevation (the angle of the sun above the horizon) and azimuth (its compass bearing) for every hour of every day in the reporting period. The horizontal axis is the day of the year and the vertical axis is the hour of the day. For a given day and hour of that day, the background color indicates the azimuth of the sun at that moment. The black isolines are contours of constant solar elevation. MoonThe figure below presents a compact representation of key lunar data for the spring of 2024. The horizontal axis is the day, the vertical axis is the hour of the day, and the colored areas indicate when the moon is above the horizon. The vertical gray bars (new Moons) and blue bars (full Moons) indicate key Moon phases. The label associated with each bar indicates the date and time that the phase is obtained, and the companion time labels indicate the rise and set times of the Moon for the nearest time interval in which the moon is above the horizon. HumidityWe base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night. The chance that a given day will be muggy in Monaco is increasing during the spring, rising from 0% to 6% over the course of the season. For reference, on August 5, the muggiest day of the year, there are muggy conditions 52% of the time, while on January 1, the least muggy day of the year, there are muggy conditions 0% of the time. WindThis section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages. The average hourly wind speed in Monaco is decreasing during the spring, decreasing from 8.6 miles per hour to 6.7 miles per hour over the course of the season. For reference, on November 25, the windiest day of the year, the daily average wind speed is 8.8 miles per hour, while on August 9, the calmest day of the year, the daily average wind speed is 5.9 miles per hour. The wind direction in Monaco during the spring is predominantly out of the east from March 1 to May 24 and the south from May 24 to May 31. Water TemperatureMonaco is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water. The average surface water temperature in Monaco is rapidly increasing during the spring, rising by 10°F, from 56°F to 66°F, over the course of the season. Growing SeasonDefinitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere). While it does not do so every year, freezing temperatures are seen in Monaco over some winters. The day least likely to be in the growing season is January 16, with a 66% chance. 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. In this report, we use a base of 50°F and a cap of 86°F. The average accumulated growing degree days in Monaco are rapidly increasing during the spring, increasing by 756°F, from 99°F to 854°F, over the course of the season. Solar EnergyThis section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation. The average daily incident shortwave solar energy in Monaco is very rapidly increasing during the spring, rising by 3.4 kWh, from 3.6 kWh to 7.1 kWh, over the course of the season.

Data SourcesThis report illustrates the typical weather in Monaco, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

DisclaimerThe information on this site is provided as is, without any assurances as to its accuracy or suitability for any purpose. Weather data is prone to errors, outages, and other defects. We assume no responsibility for any decisions made on the basis of the content presented on this site. We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands. We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
