The Nationwide Facilities for Environmental Data (NCEI) reviews a preliminary statewide common temperature of 78.8°F, which ranks as our 18th-warmest July since 1895.

With Raleigh being one of many hottest spots within the state final month, we’re reminded of the City Warmth Island Temperature Mapping Marketing campaign performed final July in Raleigh and Durham. Volunteers outfitted with temperature sensors drove, biked, and walked each cities, and we discovered some sharp variations between the most popular and coolest areas. For extra on that undertaking, together with maps of the noticed temperatures, take a look at our UHI web site.

That cool climate was fleeting, as excessive stress constructing over the Carolinas once more elevated us into the 90s early within the following week. We additionally completed the month on a stretch of days with temperatures the higher 90s, and the Moist Bulb Globe Temperature — a measure of human warmth publicity — reached excessive ranges throughout components of the Piedmont and Coastal Plain, which meant warmth exhaustion might happen in as little as quarter-hour for these working or exercising in direct daylight.

Nevertheless, we’re actually in higher form than we have been one month in the past, with Extreme Drought within the Coastal Plain washed away by July’s rainfall.
Scouting the Summer time with Our Almanac Characteristic
Final spring, we launched our Cardinal system as a brand new strategy to request and retrieve historic climate information. Eighteen months and greater than 4,000 requests later, Cardinal remains to be going robust – however that doesn’t imply we’re completed making enhancements!
In July, we unveiled a brand new addition to Station Scout, our software for exploring climate stations throughout the state. The Almanac function helps put latest circumstances right into a historic perspective utilizing rankings, ranges, and different shows.
To see what the Almanac can supply, let’s begin by taking a look at how humid the previous month was in among the wettest areas. In Hickory, the common July humidity of 81.4% was the 2nd-highest out of the previous 25 years.
Clicking that color-coded statistic opens an inventory of all Julys ranked by their relative humidity, which exhibits that solely July in 2003 was muggier in Hickory.
We will additionally see how our temperatures stack up to date this summer time. Raleigh is on tempo for its Third-warmest summer time on document primarily based on its imply temperatures, and its 4th-warmest primarily based on the utmost and minimal temperatures.
To see when the temperatures have been the most popular, click on on a parameter identify, equivalent to “Avg. Max Air Temperature”, to disclose a desk of each day observations. This clearly exhibits the three days this yr when Raleigh has reached 100 levels – and people comfy spring days we lengthy for amid our latest warmth.
Lastly, in areas the place storms have blown by way of, we are able to see how windy the previous month was. In Southport, this was the 2nd-windiest July out of the previous 18 years. Solely July 2012 had a better common wind pace.
To view these statistics for stations in your space, take a look at our Station Scout software, select a station utilizing the map and search choices, after which click on on the “Almanac” tab on the prime of that station’s web page.
You may choose a customized date and consider information starting from a single day to the year-to-date to date. That makes Scout an much more highly effective strategy to discover and visualize our climate.
