The figure below shows you a compact characterization of the hourly average temperatures for the quarter of the year centered on November. 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 month of November in Isle of Man experiences essentially constant cloud cover, with the percentage of time that the sky is overcast or mostly cloudy remaining about 61% throughout the month. The clearest day of the month is November 23, with clear, mostly clear, or partly cloudy conditions 40% of the time. For reference, on January 27, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 66%, while on July 14, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 51%. PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Isle of Man, the chance of a wet day over the course of November is decreasing, starting the month at 46% and ending it at 40%. For reference, the year's highest daily chance of a wet day is 47% on January 3, and its lowest chance is 26% on June 7. RainfallTo show variation within the month and not just the monthly total, we show the rainfall accumulated over a sliding 31-day period centered around each day. The average sliding 31-day rainfall during November in Isle of Man is essentially constant, remaining about 3.5 inches throughout, and rarely exceeding 5.8 inches or falling below 1.6 inches. SunOver the course of November in Isle of Man, the length of the day is rapidly decreasing. From the start to the end of the month, the length of the day decreases by 1 hour, 37 minutes, implying an average daily decrease of 3 minutes, 20 seconds, and weekly decrease of 23 minutes, 20 seconds. The shortest day of the month is November 30, with 7 hours, 45 minutes of daylight and the longest day is November 1, with 9 hours, 22 minutes of daylight. The earliest sunrise of the month in Isle of Man is 7:20 AM on November 1 and the latest sunrise is 54 minutes later at 8:14 AM on November 30. The latest sunset is 4:42 PM on November 1 and the earliest sunset is 43 minutes earlier at 3:59 PM on November 30. Daylight saving time is observed in Isle of Man during 2024, but it neither starts nor ends during November, so the entire month is in daylight saving time. For reference, on June 20, the longest day of the year, the Sun rises at 4:43 AM and sets 17 hours, 12 minutes later, at 9:55 PM, while on December 21, the shortest day of the year, it rises at 8:36 AM and sets 7 hours, 19 minutes later, at 3:55 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 November 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 Isle of Man is essentially constant during November, remaining around 0% throughout. For reference, on July 16, the muggiest day of the year, there are muggy conditions 0% 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 Isle of Man is gradually increasing during November, increasing from 19.7 miles per hour to 20.3 miles per hour over the course of the month. For reference, on January 2, the windiest day of the year, the daily average wind speed is 21.9 miles per hour, while on June 13, the calmest day of the year, the daily average wind speed is 12.3 miles per hour. The hourly average wind direction in Isle of Man throughout November is predominantly from the west, with a peak proportion of 40% on November 10. Water TemperatureIsle of Man 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 Isle of Man is gradually decreasing during November, falling by 3°F, from 55°F to 52°F, over the course of the month. 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). The growing season in Isle of Man typically lasts for 8.9 months (272 days), from around March 11 to around December 8, rarely starting after April 21, or ending before October 29. The month of November in Isle of Man is more likely than not fully within the growing season, with the chance that a given day is in the growing season rapidly decreasing from 88% to 59% over the course of the month. 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 Isle of Man are essentially constant during November, remaining within 16°F of 1,141°F throughout. 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 Isle of Man is gradually decreasing during November, falling by 0.6 kWh, from 1.2 kWh to 0.6 kWh, over the course of the month.

Data SourcesThis report illustrates the typical weather in Isle of Man, 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.
