On the weekend of the 108th anniversary of the bogus 134F maximum temperature report in Death Valley, a very high-end heat wave plopped itself on top of the Death Valley region. \u00a0Numerous all-time record high temperatures were set or tied or threatened. \u00a0And, I was at Furnace Creek and I was taking a bunch of pictures and temperature readings on Saturday, July 10, when an official max temp of 129.4F was attained! \u00a0(See my separate entry here for the details and pics from the July 10 visit.)<\/a> \u00a0The max temp of July 9th was 130.0F, exceeding last August’s record of 129.9F.<\/p>\n This web site entry is generally your one-stop web site for meteorological data and information with regard to the big desert heat wave of July, 2021. \u00a0My analysis and a lot more details and\u00a0comparisons to previous heat waves is in this separate Stormbruiser entry.<\/a><\/strong><\/p>\n Below is a slew of media articles on the event and on the 130F temp on July 9.<\/p>\n

the hourly temperature provided is the HIGHEST temperature attained during the previous hour. \u00a0Thus, a value of 105F at 3 p.m. at a CARB station (including the one near Cow Creek in Death Valley) means that the temperature got as high as 105F from 2 to 3 p.m., and it does not necessarily mean that the temperature was 105F at 3 p.m. \u00a0However, temperature sensors at the CARB stations are generally well above the ground. \u00a0This, and because they are generally very-well sited and well-exposed, results in a comparatively small intra-hourly temperature change. \u00a0In most instances, the temperature indicated by the CARB station at a particular hour is very close to the actual temperature at that time of day (i.e., within a degree or two F). \u00a0A little more info on this CARB station is in a previous Stormbruiser entry<\/a> (towards the bottom).<\/p>\n Link to detailed hourly Death Valley<\/a>\/Furnace Creek\/NWS\/HADS station data. \u00a0Click on the timeframe desired and

link<\/a> outlines the type of station and measurements for the USCRN station at Stovepipe Wells. \u00a0Maximum and minimum temperatures are based on 5-minute averages which are updated every 10 seconds. \u00a0 The five-minute averages themselves are derived from temperature readings taken every two seconds by three thermometers! \u00a0This is a very conservative methodology to determining the daily max and min temperatures, but is basically the same as at the NWS\/FAA ASOS stations at airports. \u00a0Both use 5-minute averages to determine the air temperature.<\/p>\n Someone in the government<\/a> does the same thing that I do: \u00a0they compare maximums between Stovepipe Wells and Furnace Creek!<\/p>\n Note: \u00a0I have found that many, if not most of the RAWS stations are rather poor on daytime temperature measurement during sunny conditions and light winds. \u00a0With such conditions, the temperature is often several degrees too high at RAWS stations. \u00a0I figure that this is likely due to generally lousy radiation shields for the temperature sensor. \u00a0However, I have not found the Saratoga Springs RAWS station to have such inflated daytime temperatures.<\/p>\n <\/p>\n More info on the exposure of the official Death Valley station.<\/a><\/p>\n <\/p>\n Inyo County Stations<\/strong><\/p>\n HUNTER MOUNTAIN RAWS<\/a>\u00a0
