I did a full summary of July on Briefed by Data and here is a highlights from the post.
First, Figure 1 represents the July historical temperature anomaly. It was certainly a record-setting year for July, on the order of 0.75 °F above the previous record anomaly. It should be noted that ENSO status will not be formally determined for some months. How does this compare to all months?
July’s anomaly was not even a top 10 for a month (see Figure 2 in the post) but it was a warmest month on record, but this is an artifact of July being the warmest month of the year in general. Read more here which includes links to the data.
