Measured temperature at approximately 2 meters above the surface of an open field (black dots) and 6, 12, and 24-hour lows (horizontal blue lines) and highs (red lines), placed above the hourly average temperature (faint purple line), with 25th to 75th and 10th to 90th percentile bands. Civil twilight and night are indicated by shaded overlays.
Cloud coverage, color coded by the percentage of the sky covered by clouds, and the heights of the reported cloud layers (black dots and lines).
Solar Elevation on Sunday, August 18, 2019
Elevation of the center of the Sun above (positive) or below (negative) the horizon (black line). Yellow and gray fills indicate day and night, respectively. Light gray lines are the corresponding curves for the winter and summer solstices. Civil twilight and night are indicated by shaded overlays.
The reported dew point at approximately 2 meters above an open field (black dots), with corresponding categorical humidity comfort levels reported in the bar along the top of the chart. Civil twilight and night are indicated by shaded overlays.
Wind Speed on Sunday, August 18, 2019
Measured wind speed at approximately 10 meters above an open field (black dots). Civil twilight and night are indicated by shaded overlays.
Wind Direction on Sunday, August 18, 2019
Measured wind direction at approximately 10 meters above an open field (black dots). Civil twilight and night are indicated by shaded overlays.
Visibility on Sunday, August 18, 2019
Measured visibility (black dots). Note that a maximum visibility (often but not always 10 miles) is reported if the visibility exceeds the maximum. Civil twilight and night are indicated by shaded overlays.
Atmospheric Pressure on Sunday, August 18, 2019
Atmospheric pressure (black dots), as measured by the altimeter setting reported in e.g. a METAR report. Civil twilight and night are indicated by shaded overlays.

This report graphically illustrates the historical weather reports recorded by the weather station at Jack Northrop Field/Hawthorne Municipal Airport on Sunday, August 18, 2019.
Aiport weather stations throughout the world routinely issue METAR weather reports . Such reports are used by pilots, air traffic controllers, meteorologists, climatologists, and other researchers. They are published via radio transmission and on the internet. We have been collecting and archiving published METAR reports since 2011, and have found third-party sources for archived reports from years prior to that.
The 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.
