Weather Eye, June

My weather figures come from thirty miles or so up the coast because I haven’t found any stations closer to Filey that can supply over half a century’s worth of data. The Whitby Coastguard data from 1962 to 2013/14 can be downloaded from the Met Office website. One of the Whitby Weather Underground stations has given me full years of data from 2010 to the present.

For the blog I will only use Daily Maximum Temperatures and Precipitation to describe the local weather. Thirty miles is quite a distance where micro climates are concerned but my observations will be so general that I don’t think it matters much to use Whitby as a proxy for the Filey experience. (There can be several degrees centigrade difference some days and storms can dump 15mm of rain on one town but not the other – but when the averages are calculated these differences all but vanish.)

The month of June delivers maximum daily temperatures in the high twenties here on the Yorkshire coast – but not often and the average rarely breaks 20°C. (I have just noticed that June 2003 tied with 1976 at 20.2 degrees; 20.1 in 2006.) The trendline indicates Yorkshire warming.

AvMaxBaseCF2017_JanJunejpgI chose a baseline period of 1979 to 2000 to enable comparisons to be made between this part of the world and major regions of the globe on Climate-Reanalyzer. It also tips a wink at the nonsense of the political figure of 2°C, the amount of warming we must avoid if we are not to compromise all life on earth. The baseline for the global comparison is usually given as the beginning of the Industrial Revolution and having lived for a quarter of a century in one of its Cradles I naturally think “1709” (Abraham DARBY, FST ID KVLT-8V2) – but 1850 is more often invoked. This graph shows that Whitby in June has warmed 3.5°C in the 38 years since the beginning of “my” baseline. (I know, January hasn’t risen much, and Whitby isn’t the world.)

Jun2017maxCF2016This third graph says quite a bit about June 2016 and 2017 if you look at it from the right angle. It doesn’t show the difference between the daily maximums on the same date but rather compares the ongoing average of the daily maximums throughout the month. June last year opened with a cool spell and this year a warm one. The second week flipped somewhat and we had to wait for the short heatwave of the 17th to 19th this year to push the declining difference up again, though even the month’s top temperature (28.9°C on the third heatwave day) doesn’t impact the average all that much. But you can clearly see we had some rather cool days compared to 2016 in the final week.

PrecipJanJunBaseCF20172017 has been a dry year so far. February precipitation was exactly the same as Baseline but the other four months were deficient, chronologically, in 21.4, 24.0, 25,1 and 18.3mm of rainfall. This graph indicates what a deal this is. It’s approaching half of what we are used to receiving.

I heard a radio Weather Man a couple of days ago say that this June might end with record rainfall figures. Well, 37.5mm over Baseline isn’t all that much to shout about.

Here are the June rainfall totals from 1962. The past rolls up like a carpet behind me and I don’t remember much about 1982. Ditto 1997, but 2007… every Filonian will remember that one. My memory places the Coalbrookdale flood in June and I have always assumed Filey suffered its inundation at the same time. Checking online it appears that the big storm hit this coast on the 18th July. (Warmer temperatures put more moisture in the atmosphere. I don’t think this graph needs a trendline!)

From wet to dry – here’s the chap responsible for Today’s Image (previous post).
