Solar Elevation on February 23, 2020
We 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 of muggy, oppressive, or miserable conditions in Valparaíso on February 23 varies over the course of the day, with an average daily chance of 3%.
The muggiest time of day on February 23 is around 8:30 PM, with muggy conditions 9% of the time.
The least muggy time of day is around 11:30 PM, with muggy conditions 0% of the time.
For reference, on February 3, the muggiest day of the year, there are muggy conditions 4% of the time, while on July 25, the least muggy day of the year, there are muggy conditions 0% of the time.
Humidity Comfort Levels on February 23

This 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 Valparaíso on February 23 varies throughout the day, with a daily average of 9.8 miles per hour.
The windiest time of day is around 3:45 PM, with an average hourly wind speed of 13.1 miles per hour, mostly staying between 10.8 miles per hour and 15.1 miles per hour, and rarely falling below 9.5 miles per hour or exceeding 17.8 miles per hour.
The calmest time of day is around 7:30 AM, with an average hourly wind speed of 6.7 miles per hour, mostly staying between 4.1 miles per hour and 8.9 miles per hour, and rarely falling below 2.4 miles per hour or exceeding 11.4 miles per hour.
For reference, on December 4, the windiest day of the year, the daily average wind speed is 11.1 miles per hour, while on May 20, the calmest day of the year, the daily average wind speed is 8.6 miles per hour.

Wind Direction on February 23
Valparaíso 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 does not change appreciably over the course of the day, so this section does not include a chart.
The average surface water temperature on February 23 in Valparaíso is 63°F, mostly staying between 61°F and 64°F, and rarely falling below 60°F or exceeding 65°F.
For reference, the year's highest average is 63°F on February 9, and its lowest average is 55°F on August 20.
Shortwave Solar Power
This section discusses the incident shortwave solar power 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 peak incident shortwave solar power per square meter is 0.99 kilowatts at around 1:45 PM.
In contrast, the corresponding value on December 27, the brightest day of the year, is 1.09 kilowatts at around 12:45 PM. The corresponding value on June 22, the darkest day of the year, is 0.44 kilowatts at around 11:45 AM.

Temperature and Dew Point
There is only a single weather station, Viña del mar Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Valparaíso.
At a distance of 17 kilometers from Valparaíso, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.
The station records are corrected for the elevation difference between the station and Valparaíso according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.
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.
All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.
Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.
Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.

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.
