Yes, that's what it is. It fluctuates during the day as moisture from, say, the ground, is evaporated into the air and lifted high up in thermals. You generally see it rise again overnight as the thermals stop and the ground cools again. However, dewpoint is a tricky thing to accurately measure, and is actually a calculated value from the dry- and wet-bulb temperatures.

It's significant in that it can greatly change how we feel temperature. Higher dewpoints restrict cooling due to sweating, making us feel more uncomfortable.

I've been interested in this idea of Apparent Temperature, and how it relates to air temperature and dew point temps:

cloudy and mild morning with a temperature of 18C here at Dunshaughlin. A warm weekend ahead for most but certainly more cloud around than what we've been used to recently.

Lots of North American weather services include it in forecasts.

I was in Canada for a summer years ago and they included a 'Humidex' temperature which I've seen referred to else where as 'RealFeel'. I think it's a useful measure for people making decisions about going for a run, walking the dog, delaying a trip to the beach etc.

Practically Baltic in Waterford! Quite cloudy as well

Yeah, Netweather uses "Feels Like", as does Yr.no, though I don't know if they actually use the standard Apparent Weather formula for that one - "RealFeel" is actually an Accuweather registered trademark for example, which makes me think they're making up their own formula for that one.

For me, Apparent Weather is a more useful measurement than air temp for describing what the human experience of the weather is going to be. Unless you're a pro at reading all the various statistics and calculating your own version of it of course, but most people need that at a glance.

Ya, the models haven’t a clue beyond next Friday

First day in nearly 3 weeks with no sun this late in the day...not hopeful of seeing any sun today. Struggling to get above 20c and it looks like it’s going to rain , it might not but I keep expecting to look out the window to see the rain has started..

Quoted in https://www.independent.ie/irish-news/heatwave/warm-spell-isnt-going-anywhere-as-temperatures-to-reach-29c-37086648.html

“We have a 10-day horizon where we can predict what the weather will be like, but saying that we’re still able to tell when a change is on its way. We haven’t seen any indication that temperatures are going to drop so it’s unlikely that we’ll see much rain for the rest of July.”

i can imagine that the models have a mathematical bias towards getting things back to 'average' for this time of year. So, any long term outlook that isn't on par with the average will always cause a bit of a struggle for them in the 10day range. - just my 2c there

Don't know where John is getting that info from, the outlook is really firming up on the change for second half of July. I was not making up crap last night just to be pessimistic.

Could be managing the message? Compliance with the water restrictions may be impacted if he came out with "looks like rain in a week or so", and it's still FI so might not verify, as seems to have happened a couple of times in this spell?

That was when not all models were in agreement of a change, now they are even if it is FI.

They all seem to be saying the same thing that no changes for the remainder of the month...surely they have to be looking at the same charts as you guys here.
Going by by all accounts a change is happening towards the end of next week...that’s 8 days away..why then say definitely no change or rain for the 10 days..
I know people making plans for outdoor events based on the weather forecasts from met eireann ..why not tell people that a slight change on the way..

Tendency to exaggerate ? Baltic

Definitely more humid the last couple of days. It makes a big difference to the comfort level.
I see in Quebec in Canada they are really struggling at the moment as the temperature is about 34c but the humidity is so high that the real feel is about 40c.

Well it's 17 in Tallinn Was and is cooler than recent days.

19.1C here in Glasnevin and has been completely cloudy for the last couple of hours. RH is 77%.

Well that and even if a breakdown comes as shown in FI, rainfall amounts would be very little compared to what is needed.

Just talking about yeaterday's weather into perspective. Compared to recent weather Thursday the 5th July was a mediocre day. In a normal Irish summer it would be a good day and in a poor summer a great day. Temperatures from the high teens towards the mid 20s. In most areas max temperatures were only 2-3 degrees above normal. We were getting accustomed to max temperatures in excess of 10 degrees above normal in places over the last week.

second cloudy day in a row here, after very little sun here yesterday, today is looking even more gloomy than yesterday. The cloud is meant to weaken through the day allowing some glimpses of hazy sun in the afternoon and evening.

The heatwave definitely ended yesterday for Ireland with temperatures close to average since yesterday. A few warm mid 20s days ahead which are still good by Irish standards.

BBC's forecast for Ireland is caught up with yesterday's charts and showing cool and damp/drizzly days starting from next weekend into the following week.

Of course that could still change, the BBC were wrong about a breakdown over a week ago. We've had a very good run with this warm spell which will be almost 3 weeks long by next Friday. A breakdown is inevitable, it's only a matter of how soon do we get it.

I'm treating it and planning for the dry conditions or rain at levels to not matter for the next 8 weeks.

It might not be scorching but it looks like staying warm and dry for a long time yet.

Few drops of rain in Ashbourne. Radar shows some patches developing over the Greater Dublin region.

UK Met has a cloudy day with some showers developing for the Leinster region today. They are still showing a lot of cloud for Leinster tomorrow as well, but it should be sunnier than today.

It's quite gloomy here at Dunshaughlin too, full slate grey cloud, thought it was going to drizzle earlier but so far it's remaining dry thankfully.

Personly I see a shift away from extreme heat ,I don't think there will be a drastic break down.but a graduall return to average summer weather still warm and dry what would normally though of as good summer weather in Ireland
The south and east will keep below average rainfall while the north and west will have average too slightly above.
I reckon we will just have enough high pressure hanging around

Ultimate Seduction

Was everyone too worried so much about a break from the sun next week that they forgot about this weekend? Cloudy now with sunny spells for the foreseeable according to MT.

Gutted.

Sun is trying to shine through the clouds in Dublin 13 but just not getting there quite yet.

Playa del Arklow living up to its name meanwhile.
