For each station, the records are corrected for the elevation difference between that station and Oslo according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

The average daily shortwave solar energy reaching the ground per square meter (orange line), with 25th to 75th and 10th to 90th percentile bands. The figure below shows you a compact characterization of the hourly average temperatures for the quarter of the year centered on July. The average surface water temperature in Oslo is increasing during July, rising by 4F, from 57F to 61F, over the course of the month. This 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. The chance that a given day will be muggy in Oslo is essentially constant during July, remaining around 0% throughout. 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. You're permitted to use this graph as long as you provide prominent attribution with a link back close to the use of the graph. For reference, on July 18, the hottest day of the year, temperatures in Oslo typically range from 54F to 71F, while on February 7, the coldest day of the year, they range from 19F to 30F. For print usage, please acquire a license. The clearest day of the month is July 19, with clear, mostly clear, or partly cloudy conditions 53% of the time. 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). All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition , by Jean Meeus.

To 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. Haines, Alaska, United States (4,009 miles away) is the far-away foreign place with temperatures most similar to Oslo (view comparison). The highest daily average low temperature is 54F on July 21. This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. We assume no responsibility for any decisions made on the basis of the content presented on this site. 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. 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. For a given day and hour of that day, the background color indicates the azimuth of the sun at that moment. 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. Over the course of July in Oslo, the length of the day is rapidly decreasing.

The black lines are lines of constant solar elevation (the angle of the sun above the horizon, in degrees). 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 shortest day of the month is July 31, with 16 hours, 54 minutes of daylight and the longest day is July 1, with 18 hours, 41 minutes of daylight. We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Oslo. Maps are Esri, with data from National Geographic, Esri, DeLorme, NAVTEQ, UNEP-WCMC, USGS, NASA, ESA, METI, NRCAN, GEBCO, NOAA, and iPC. 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 thin dotted lines are the corresponding average perceived temperatures. 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. Weather data is prone to errors, outages, and other defects. The black line is the percentage chance that a given day is within the growing season. From the start to the end of the month, the length of the day decreases by 1 hour, 47 minutes, implying an average daily decrease of 3 minutes, 35 seconds, and weekly decrease of 25 minutes, 2 seconds. For reference, the year's highest daily chance of a wet day is 36% on August 14, and its lowest chance is 23% on March 19.

A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. Daylight saving time is observed in Oslo during 2022, but it neither starts nor ends during July, so the entire month is in daylight saving time. The solar day over the course of July. The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray. From bottom (most yellow) to top (most gray), the color bands indicate: full daylight, twilight (civil, nautical, and astronomical), and full night.

The thin dotted line is the corresponding average snowfall. For reference, on January 6, the windiest day of the year, the daily average wind speed is 5.0 miles per hour, while on August 3, the calmest day of the year, the daily average wind speed is 4.0 miles per hour. Lower dew points feel drier and higher dew points feel more humid. The black isolines are contours of constant solar elevation. Oslo is located near a large body of water (e.g., ocean, sea, or large lake). 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. The figure below presents a compact representation of key lunar data for July 2022.

Definitions 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 ( 32F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere). The average sliding 31-day rainfall during July in Oslo is essentially constant, remaining about 3.1 inches throughout, and rarely exceeding 5.7 inches or falling below 1.1 inches. Time zones for airports and weather stations are provided by AskGeo.com . The estimated value at Oslo is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Oslo and a given station. MERRA-2 Modern-Era Retrospective Analysis.

The average accumulated growing degree days in Oslo are increasing during July, increasing by 371F, from 456F to 827F, over the course of the month. Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data. 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. From bottom to top, the black lines are the previous solar midnight, sunrise, solar noon, sunset, and the next solar midnight. 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. We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series.
