July Weather Records

[Osbourne One-Nil]

Well, the most notable feature was, of course, the rainfall. July ended up being the 9th wettest month since I started recording in 1997 with 213.4mm falling and only six days when it didn't rain. I also had the 2nd warmest night I've recorded; a minimum of 17.7C on the 2nd, beaten only by July 2nd (!) 2001, the second lowest July minimum; 4.2C beaten only by 2.5C on July 15th 2001, and the highest temperature for three years; 28.6C, which is the highest since it reached 29.3C on July 25th 2006.

The statistics are:

Average daily maximum, 19.1C

Highest daily maximum, 28.6C (2nd)

Lowest daily maximum, 13.2C (17th)

Average daily minimum, 10.8C

Highest daily minimum, 17.7C (2nd)

Lowest daily minimum, 4.2C (11th)

Mean daily temperature, 15.0C (eleven year mean, 15.2C)

So after 2 hot days a pretty average month temperature wise

Rainfall total = 77.6mm with 20.4mm on 17th, so much wetter than normal and most parts of this area will have had 25% more than I’ve recorded.

22 days with 0.2mm or more and 18 with 1.0mm or more.

Absolute max=31.3C on 1st with lowest daytime max of 16.8C on 29th

Lowest min=8.1C on 31st and warmest night was 15.1C on 5th

No fog or thunder reported

Highest daily total was 22.3mm on 11th with 7 days over 10mm.

Average wind speed was 8.3km/h Westerly but this is a fairly sheltered area.

There was only 3 days with temperatures over 20C, 10 days below 17C and 3 below 16C

This is my first year of recording so I don't have any of my own long term averages but judging by local stations the average maximum should have been around 19.5C making this months maxima around 1.8C below average.

[Andy Bown]

There were 5 dry days in the opening 7 and then only 2 (yes that's TWO) more in the next 24 days!! After the first 2 days reached 31.7c & 29.3c the temperature never got above 24c again!

Average max = 20.20c (highest = 31.7c on 1 July)

Average min = 12.57c (lowest = 8.8c on 10 July)

Mean = 16.38 (lower than June's mean which is very rare!)

Dry days = 7

Rain days = 24

Rainfall = 130mm

Weather summary and stats for July 2009, Lampeter, Ceredigion

Summary: Very wet, quite dull, near average temperatures

This July was a month that held promise of being a warm, perhaps even dry Summer month, a hope that was well and truly dashed!

The hot weather of late June held on for the first two days, it reached 28c on the opening day, which is the best of the Summer so far. The 2nd saw the change from warmth to the very unsettled and very wet conditions that would last the entire month!

From the 3rd onwards a succession of lows crossed the British Isles (often over England and Wales), bringing spells of rain and showers, these very heavy at times. It was rarely dry for very long- indeed the 9th was the only day without any rain falling. The 16th was the wettest day locally for over 3 ½ years with 55.5mm.

Temperatures were unremarkable, with maxima from the 3rd onwards mostly in the 17-22c range, i.e. close to the seasonal average. Only one day- the 17th- was notably cool, this reaching only 14c.

Only a few days this July experienced prolonged sunshine, rather they were rather cloudy with sunny spells at best. Winds were often moderate to fresh, but never really strong. They predominated from southerly and westerly quarters, with an absence of easterlies. Relative humidity averaged 84% which was the highest monthly mean since March (85%).

From a storm perspective, July failed to deliver- with no days during which thunder was heard, this comparing very unfavourably with the Midlands, from where relatives seemed to provide frequent reports of thunder and lightning!

The wettest July on record and the 5th with rainfall above 150% in the last 6 years. 1.0mm of rain or more fell on 21 days - the highest total of any month since my records began. Just 7 days had no rainfall at all. Unsuprisingly in such a wet month, daytime temperatures were close to average but minimum temperatures were warm - a result of cloudcover. It was also rather windy, just two days had a mean wind strength of less than 10mph.

The month started on the warm and settled note where June left off. The first 5 days had a mean of 19.3°C, nights were warm and days pleasant, reaching 24.5°C on the 4th, the warmest day of the month and summer so far. The 7th then saw the change to wetter weather, bringing the first thunderstorms of the year. The first shower was exceptionally heavy and dropped over half an inch of rain in 30 minutes.

The rest of the month was then unremittingly wet, with a combination of bright showery days and dull, overcast ones. On the plus side, the month had 6 days where thunder was heard and 9 storms passing over in total. However, after the 11th, just 2 days were dry. Temperatures were rather average though, with few extremes either by day or night.

Overall, another disappointing month. It was slightly warmer than 2007 and 2008, but much wetter.

Temp + rainfall graph for the month.

Forgot to mention - A few problems with the temp/hum sensor towards the end of the month as can be seen in the graph. Turned out the sensor was faulty and oddly loss of readings was associated with rain and damp weather (especially drizzle). This got worse on a mild wet humid day on the 4th August and lasted until the 6th when I Replaced the sensor which fixed the problem!

[Thundery wintry showers]

Finally my records are in for Cleadon. Averages are estimated for 1971-2000. At some point in the next few weeks, probably not this week but the week after, I will be updating my website with the estimated long-term averages for 1971-2000 and a different format for presenting the data.

Mean Max 19.8C (+0.7)

Mean Min 12.7C (+1.0)

Highest max: 23.0C (1st)

Lowest min: 9.1C (31st)

Precipitation : 127mm (265%)

Wettest day: 44.0mm (17th)

Days of thunder: 7

Days of hail: 1

Days of fog, sleet/snow, gale: 0

This was a phenomenally wet month, but with an unusually high proportion of the rain coming from convective precipitation (heavy showers & thunderstorms) and so sunshine was, at worst, only a little below normal. It was also phenomenally thundery- with 7 thunder-days, the most thundery since I started recording in 1993, and Newcastle Weather Centre's records suggest that it was the most thundery month in the region since June 1980. The exceptional rainfall made this the wettest calendar month since August 2004, and the wettest July since before 1993.

The first week produced four of the thunder-days, and was dominated by sunshine and showers. After that, the Atlantic took charge and the weather featured frequent heavy showers, sometimes with a fair amount of sun in between, while at other times it was mainly cloudy. It was very dull and wet around the 17th, which was the wettest day of the month with some 44mm of rain and a maximum of only 14.2C.

After a warm first week temperatures were consistently near-normal by both day and night, and consequently the mean temperature was slightly above normal making it the warmest July since the exceptional 2006.

Up to the end of July, 2009 had repeated 2007's feat of having no maximum of 24C or above, but my records up to 15 August indicate that 5 August (24.5C max) breached that threshold.
