July 2019 and August 2018 were perfect examples of that. Seemed fairly average/mediocre on paper but because of the 'Weekend Curse' felt like utter garbage.


This month has been utter garbage no matter how you look at it. Pretty much zero decent weather whatsoever. Today was another vile day - drizzled all day long for a total of 1.4mm and this is what we are seeing constantly. Day after day of November like drizzle and light rain that is not adding up to much but is just completely writing off the summer. Intense downpours and thunder would produce higher rain totals but would, at least, feel more like summer than this grim rubbish.


10 days in a row of measurable rainfall and no end in sight so could potentially even beat the ridiculous stretch of 14 consecutive rain days from 21st June to 4th July 2012 which is the longest I have recorded in summer over the past 14 years. If that were to happen it would assure this summers place as one of the most dismally unsettled of all time. Only the very sunny second half of June has saved it from being exceptionally dull as well like so many since 2007.



I think that is a perception of the weather pattern rather than a measurable phenomenon. Doubtless it is possible to get a short run of "unlucky" cycles where the weekends have worse weather but this is just a coincidence and over the long term it all averages out.


If this were real there would be a known long term 7 day cycle with quantifiable data and a cause.

The thing with the so-called 'weekend curse' is we simply notice more when poor weather coincides with the weekend. After a fine week on Friday evening cloud starts spilling in heralding a wet Saturday - Typical, you think to yourself, just in time for the weekend! But nobody notices this happening on a Tuesday night before a wet Wednesday. It would be interesting for me to have a look at my own records to see if the weekend weather really is any worse on average than during the week and hopefully disprove the weekend curse, well for my area at least. I don't think you'll ever convince Richard though!

The weekend curse is a valid point when it comes to human perception, which is more about the amount of usable weather we get in our free time!  It hasn’t really applied to me as I work short hours in the summer and have had time to enjoy many weekdays in the garden this year hence, it’s been a good summer for me.  Which is probably why human experience can be at odds with stats.  


On the other hand, stats don’t change once they’ve been recorded, whereas memory is unreliable.  When I were a lass, summers were sunnier and winters were snowier!  Actually, they weren’t but I remember the odd special occasion when the weather sticks in my mind and that clouds my judgement.  


The most extreme weather has been during my adult life, not my childhood.  In June 2007, the local river flooded for the first time in my life.  We had the heaviest and longest lasting snow in 2010, although I experienced the sixties winters.  Summer 2018 was one of the best, although I experienced 1976 and 1959.  July 25th 2019 broke temperature records here and this summer will go down in my memory as a very good one because there were so many usable days.

And it's raining yet again here in Wharfedale. Although we get some sunshine, usually afternoons, I don't think we've had a sunny start to a day this month and only 2 dry days out of 17!! Rainfall totals around these parts are now over 150mm. August is fast becoming my least favourite month!

No it's not just perception. It is a measured fact that the summer weekends see worse weather than weekdays. Only two years since 2007 - 2015 and 2017 - have seen sunnier weekend weather than weekdays and in several of the summers the difference has been considerable.


Here are my records from 2007:


Year, Weekday sun, Weekend sun, overall sun



















































































20074.302.633.83
20084.794.044.57
20095.734.875.49
20104.934.524.82
20114.783.934.54
20123.413.313.38
20136.266.116.22
20145.724.765.44
20155.225.445.28
20164.834.534.74
20174.725.705.00
20186.955.946.66
20195.905.035.63

It doesn't average out over time as there has been an 11% difference in daily sunshine average between weekend and weekday over the 13 year period (5.18 v 4.68). More than backs up my frequent complaints about having to sit in a stifling office when it's sunny outside only to wake up to grim overcast come the weekend. Not so much of a difference with rainfall.


As for today, after a promising start it's turned to crap again and I just got soaked by a shower. No 'Weekend Curse' this month as it's just dreadful all the time.  11 days in a row of this now

A lovely day on the Lizard Pilot Gig rowing. Early cloud gave way to blue sky and the cove at Cadgwith was sheltered from the fresh breeze.

Well, it won't be long now before it will be time to start the autumn moaning thread (I see that Netweather have already started their autumn moaning thread, having done so back in July). Once that it comes to that time, that would probably just be a moaning thread as I would expect there to be too many reasons for gloating there.

Nice day, with only a few spots of rain this morning.


Even managed a BBQ tonight.

17th July-16th August 2019: provisionally 201mm for the region. This wet spell all started on the 17th July


How does that compare to 31 day calendar months for the region?


Wettest January on record: 227.8mm in 1928


Wettest March on record: 178.3 mm in 1981


Wettest May on record: 141.2mm in  1924


Wettest July on record: 171.1mm in 1988


Wettest August on record: 238.4mm in  1956


Wettest October on record: 233.7 mm in 1967


Wettest December on record: 271.6mm in  2015


So that period is up there amongst the wettest spells ever recorded during summer.

This has to be up there with the most stupefyingly boring and non-descript months of all time. It's utterly dire - nothing of interest is happening and it's not at all pleasant.


It's just day after day of cloudy skies, moderate temperatures and nuisance value rain. It's not reached 22C, there's been one night below 8C, no day has recorded 12 hours of sun and there has been just 38.6mm rain but only four completely dry days.

Not been that bad here really over the past week - a couple of days were washouts but the rest were decent with only a few showers and sunny spells with temperatures of 19-20C which is a bit below average but could be worse. Rainfall is sitting at around 43-44mm here, which isn’t bad at all when the LTA for August here is 58mm. 


This month should finish comfortably warmer than average based on the current warm output. Not dissimilar to last August really but probably cloudier. Even warm summer months in recent years have tended to be rather cloudy.

Just had our daily cloud burst. It's become part of the summer really. No matter what the forecast is for the day, there will always be at least one spell of rain
