Numbers released today by NOAA’s National Climatic Data Center show that not only has July been abnormally cool in the USA, but so has 2014 in general. For the last 30 days, there have been 574 record highest temperatures in the USA, and 1,726 record lowest. A ratio of 3 to 1, indicating that July was very cool. But, the year so far has also been cool.

So far for the USA year to date, the numbers of record lows outpace the highs two to one.

This year, here have been been 12,644 daily record lowest temperatures versus 6,615 record highest temperatures in the USA, a ratio of 1.91 to 1.0.

For all types of high and low daily records for the year to date, there were 29,372 cold records versus 16,761 warm records, a ratio of 1.75 to 1.0

If all high and low daily record types are considered for the last 365 days, cold still outpaces warm. There are 46,712 cold records versus 36,650 warm records.

The ratios for monthly all time records also see cold records outpacing warm ones.

From the National Climatic Data Center:

The summaries below list the number of records broken for several recent periods is summarized in this table and updated daily. Due to late-arriving data, the number of recent records is likely underrepresented in all categories, but the ratio of records (warm to cold, for example) should be a fairly strong estimate of a final outcome. There are many more precipitation stations than temperature stations, so the raw number of precipitation records will likely exceed the number of temperature records in most climatic situations.

For all time records, cold and warm records are about evenly balanced for 2014, with 28 warm records year-to-date versus 32 cold records.

As mentioned earlier by NCDC recent records (30 days or less) are probably underrepresented.
