Heat is responsible for the most weather-related fatalities in the U.S., having a higher toll than floods, tornadoes and hurricanes. “Downtown LA typically hits 90°+ for the first time around mid-April, but this year we still have not hit 90°,” he explained.īiggar wrote that the heat could be dangerous since residents have adjusted to cooler-than-normal temperatures. Though things will seem hot this weekend, Biggar wrote that temperatures have been rather low this year.

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. 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 draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. We assume no responsibility for any decisions made on the basis of the content presented on this site. Weather data is prone to errors, outages, and other defects. The information on this site is provided as is, without any assurances as to its accuracy or suitability for any purpose. Time zones for airports and weather stations are provided by. Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database. Land Use data comes from the Global Land Cover SHARE database, published by the Food and Agriculture Organization of the United Nations.Įlevation data comes from the Shuttle Radar Topography Mission (SRTM), published by NASA's Jet Propulsion Laboratory. 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. The stations on which we may fall back include but are not limited to Jack Northrop Field/Hawthorne Municipal Airport, Los Angeles International Airport, Santa Monica Municipal Airport, Burbank Bob Hope Airport, Long Beach Airport, Van Nuys Airport, Long Beach, and Mount Wilson.Īll 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.Īll other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis.

For a given day of the year and hour of the day, the fallback station is selected to minimize the prediction error over the years for which there are measurements for both stations. In the case of missing or erroneous measurements from this station, we fall back on records from nearby stations, adjusted according to typical seasonal and diurnal intra-station differences. These records are obtained from NOAA's Integrated Surface Hourly data set, falling back on ICAO METAR records as required. When available, historical temperature and dew point measurements are taken directly from this weather station. Los Angeles / USC Campus Downtown has a weather station that reported reliably enough during the analysis period that we have included it in our network.

This report illustrates the typical weather at Los Angeles / USC Campus Downtown, based on a statistical analysis of historical hourly weather reports and model reconstructions from Januto December 31, 2016.
