As the temperature rose to 42°C in Lampang and Tak, several other provinces cited 41-40°C on Thursday morning, the Thai Meteorological Department warned residents in the north, northeast, centre and east of very hot weather with possible storms during April 13-17.

 

People must beware of stormy weather and gusty wind and stay away from big trees and unsecured billboards, the agency said.

 

At 5am the temperature was forecast for Loei and Kanchanaburi at 41°C while Mae Hong Son, Nan, Phetchabun, Khon Kaen, Nakhon Ratchasima, Ubon Ratchathani and Nakhon Sawan were set for 40°C.

Been 42° in Kanchanaburi most of this week. Always is this time of year. That's why it is the hottest place in the Country.

and yet that's where they say the girls with the coldest hearts come from...

What's the relative humidity like?  If the heat index temperature is the same as the recorded temperature, ie 40-42 deg C, then yeah it's hot, but still bearable (barely) with a fan.

 

But at least you can run evaporative coolers over there.

No more than 40°C according to weather websites.

I have been reading 42c on my thermometer for the past three days, "some" weather websites show only 40c, my thermometer reading is correct, so who is right.

If i stand outside on the concrete drive the temp is well into the 50c, or is it - if some website doesn't tell me it is 50c+ is it wrong.

The way temperature is reported has long amused me, if I am seeing and experiencing 50c that is what it is, no matter what "some" website" says.

There will always been someone chirps up that it is not "official" as the "officials" say not - nonsense..........

It all depends where you put your thermometer.

The only place to get an accurate reading is in a properly screened holder.

The measurement refers to air temperature in the shade.

If you fix your thermometer to a wall that's absorbing heat all day then that gives you the wrong reading. Too close to the ground it gets radiated heat from the ground giving you a higher than it should be reading.

Unless your thermometer comes with a real certificate proving it has been calibrated then domestic thermometers are only a good guide, could be out 3 or 4 degrees.

Edit

This is the only way to get a 'real' reading.

Hi. I was about to reply but  see that @overherebc already explained it.

Anyway:

Temperature given by weather organisation respect a precise standard.

 

The thermometer must be :

- 1.50m above ground

- in the shade

- in a ventilated area

- over some earth or grass floor

...

Very easy to get very different values by not respecting one or more of these rules.

If anyone is interested you can get a good idea of humidity by doing the following.

First get the idea it's called relative humidity.

RH is the amount of water vapour in the air described as a percentage of the water vapour that air could hold at it's actual temperature and pressure without condensation taking place.

So, do in the shade, get two very similar thermometers in a holder of some kind. Fix a bit of clean white cotton on the bulb of one and wet it with water,  Still in the shade wave it around in the air for 30 seconds to a minute. Quickly read both thermometers and use the attached chart to get a good idea of the relative humidity.

The higher water vapour conditions don't allow so much evaporation from the cotton so the temp' difference from the wet and dry therms' will be smaller. Very low water vapour conditions allow greater and faster evapouration from the wet therm' so greater cooling and temp' difference ( think Sahara )

So, if you are out in the sun, stood on concrete reading a temp of 50c, this isn't a "real" reading as it doesn't fit the "criteria", really its only 40c as you are not in the shade! - exactly!

Fact remains its 50c - you can't change that! 

At what point do we just stop thinking for ourselves altogether? ????

Why not argue the point   if you're in the local butchers freezer room it won't be as warm as outside.

Anyway, the temperature you 'feel' standing on the concrete is a combined radition and covection impacted temperature.

With your arguement you could say I was in a black painted box on black concrete on a sunny day and it was 75C in the box.

Try two thermometer that are the same and put black paint on the bulb of one, stick them in the sunshine and watch what happens to the readings.

But regardless it is still the true temp I am experiencing, yet if I posted it was 50c there would be multiple posts stating impossible! as the officially recorded temp was 40c - there's a lot of variables.

You think too much 

Yes of course you can find locations at 50°C when "official temperature" is 40°C... because on the sun, over concrete or anything that makes this location hotter than standard. This is real, not your imagination 

The main point of "standard temperature" is that it allows comparison of temperatures in the time, or between different locations, cities, countries...

Well even my dogs have the sense to get in the shade.

Just sayin'

In F1 the 50c would be the track temp and the 40c would be the ambient.
