Jaysus mate. Can you make it clearer what DP means.
I had a google and it came up with some very NSFW links ��

DP stands for Dew Point ie. the temperature where dew can start to form I believe.

:pac:

He is talking about Dew Point, not... :eek:

MidMan25

24 degrees in Ballyhaise (Cavan) at 9pm!

Great conditions for sky watching too, Venus very bright in the west-northwest (will soon have set so possibly have a look next few nights, it will be there all summer) ... Jupiter low in south at sunset and low in southwest by 11 p.m. (where that's later than sunset), Antares quite low in south around midnight, bright red when seen in dark skies, then Saturn rising around 11 p.m. and prominent in south by 0100h, full moon night of 27th-28th will be close to Saturn in sky on late evening of 28th then you can't miss seeing Mars rising after 0100h and very bright red-pink colour (to my eye anyway).

You can't confuse Antares with Mars for two reasons, (a) it is much closer in the sky to Jupiter, and (b) it is about half as bright this time around, the name "rival of Mars" works better when we aren't passing Mars at its perihelion as is the case this summer (every 15-17 years we get a particularly close opposition with Mars and this year is it for the current cycle although 2020 will have nearly the same brightness a couple of months later into the year).

Also the waxing nearly full moon should be located just above and a little to the right of Antares tonight, then above and to the left of it Monday night. Antares never gets as high as the planets because it is about 4 degrees below the ecliptic plane and for example Jupiter in that segment of its orbit is 1 degree above it, Saturn a few years ago was two degrees above, so they don't pass very close, although the Moon at certain points in its orbital cycle (not anywhere near now) gets close from our perspective and can occult (move in front of) this bright star which is also "Alpha Scorpii." (the principal star in the constellation Scorpio).

Whats the relevance of Dew Point in this weather? I've only seen ye mention it around snow events before

We want the dewpoint as far away from temperature as possible. As they get closer together we get mist and then finally fog. Also the closer DP is to temp, the higher the relative humidity and the stickier it feels.

Wonder if there's any chance of either of these records being disturbed?

Highest air temperature: 33.3°C at Kilkenny Castle on 26th June 1887.
Highest air temperature recorded during the 20th Century was 32.5°C at Boora, Co. Offaly on 29th June 1976.

What an end to a perfect day.

Mercury is also visible until 11.15pm, with binoculars and a clear northwest horizon. Will be easier to locate in July.

I also wonder if the Northern Ireland record will be broken. I think the record there is only 30.8C. It's unlikely, but possible.

Cantona's Collars

Posted in the drought thread that Coolmeelagh Woods between Carnew and Bunclody is on fire tonight. Just saw a video of it and it's a major fire.

Dewpoint is a direct measure of how much water vapour there is per kg of air (i.e. the mixing ratio). Higher mixing ratio means higher dewpoint. Dewpoints above around 15 °C start to feel muggy/close/heavy...whatever strange terms we use in Ireland!

Lovely photo, similar image here at sunset tonight in south county Dublin

Meteorite58

Humidity low again tomorrow ( ARPEGE showing the lowest ). As has been mentioned more cloud about tomorrow and as a result slower to release the temperature tomorrow night, more so inland.

Kermit.de.frog

Almost 18c here in north Dublin at the moment. Feels close enough.

This will be the last of the comparatively cool nights. I have my trusty fan at the ready.

Tonight we raise the dead.

Made the most of this superb (not even) day at the Bray Seafront. Loved it!

Hirlam going for general maxima of 26-28c over the east midlands tomorrow, and similar again for the midwest on Tuesday:

Met Eireanns symbols forecasting 31c for here Tuesday. Map shows 32c over Tralee.

I love the heat, but that's bringing out the fear a little!

I know how you feel. The only time I've ever experienced 30c was on holidays as a kid in the south of France. I remember feeling like I was in an oven

Ah I've felt hotter, last year was 36c in Lanzarote and year before 40c in Turkey, but in those temperatures I always took advantage of air conditioned accommodation, shops etc. Plus alcohol was a bit of an incentive to sleep!

30C with low humidity is fine as long as you're out of direct sunlight. I've experienced up to 44C with extremely low humidity yet the hottest and most uncomfortable I've ever felt was a ~30-32C day near the equator with stifling humidity.

I find humidity is much more a factor in how comfortable the heat is than the temperature. Tomorrow looks a touch higher than today but still fairly low in the west at around 30-50% so should be bearable for most people

Air conditioning really does make a difference. I've experienced 46c before with air conditioning and fans and it was fine in the apartment. I was in Istanbul Ataturk Airport two years ago and the temperature there was 29c but it felt unbearably hot because of how busy it was and the lack of air conditioning in the place where I was.

It's not just air conditioning, Irish homes are (of course) designed to keep the heat in...which doesn't help matters on sticky nights.

I don't know what the temps were, but inland Cuba was sweltering and felt like breathing in hot water. Your body motion really slows down, like moving through treacle.

If at any point over the course of the coming week anyone feels like complaining about the heat, just think back to a few months ago when it was freezing cold, the electricity was gone, there was no running water for showers etc, and you were heading to bed at about 6pm in order to fall asleep early simply in the hope of getting another day closer to normality resuming.

Seriously, it's too hot
