Saved by a shift in wind

Though temperature hit a moderate high 38 at Don Muang today, the wind shift from off the humid gulf to the south to the drier western uplands, bringing dry air relief (lower humidity)  by noon. Good day for drying laundry.

2015 a moderate hot season so far

Notwithstanding some excited tourist twitters on the subject, I fail to find anything special about hot season heat this year. In fact early rains have tended to moderate heat buildup. If SE Asia is being threatened by global warming, it is not showing up in Bangkok temperatures.

Red is temp at Don Muang, green is dew point. Temps are topping out at about 35 C. So far, anyway.

A wet pillow last night

This is my idea of the time to turn on an air conditioner, when you begin to sweat into your pillow in the middle of the night. Turns out the room temperature was 30 degrees (86 F), dew point 25, "wet rag" temp 27. This exceeds the limit for sub-sweating body temperature equilibrium when lying on a western-style mattress. (see free sample chapter for more on this).

Moral dangers at Songkran: you've been warned!

Songkran hot season holidays: Thai Moral Promotion Center describes “great danger from sexual assault due to inappropriate attire“ even as it suggests “it’s advisable to wear as little as possible ."

Hmmmm....

Something else to worry about?

Just when we learn that doing things to "detoxify" your body is a medical myth, we now have to worry about mephitic air! 

Naaw, just kidding. This is something that Ben Franklin cooked up way back in the old days, with the result that his friend John Adams almost froze his ass one night in New Jersey on his way to sign the Declaration of Independence. Never mind, my Boston mother believed it anyway!

Read about it in Chapter 3 of the book --- If I ever get it finished! (But meanwhile get a free copy of what I hope is one of its more entertaining chapters by clicking on the cover image to the right.)

It's a bit of a breeze you'll be needing

Contrary to what you might read in standard western books on thermal comfort, people in the tropics are not really troubled by a slight breeze, by which they mean 1 to 2 meters per second. But this vastly changes their perception of temperature as you can see here. Even temperatures up to 35 deg C can be accepted with a “slight breeze”. Right axis is temperature in Celsius, left is wind velocity, meters per second. Most people find the blue zones comfortable.
