I arrived in Singapore today; I'm going to stay here for a few days and I am hence delighted to spend some time in this fantastic city, being particularly fond of it.

As usual, the weather was good, even excellent in late afternoon with very clear skies towards the evening.

The temperature stayed at around 31°C until sunset, which I found completely comfortable due to abundant breezes.

However tonight (11PM) after walking for a good hour I started feeling that the weather was unusually hot, strangely sultry, which had almost never occurred to me in Singapore in the past (and I've stayed here for several months).

Here's why :

Current conditions :
Temp : 28°C
Humidity : 94%
Wind : calm

Or, put in another way, a dew point of 27°C ! Isn't that rare even by world standards? I had never seen such a high DP in Singapore (or anywhere else, for that matter - perhaps in Hong Kong in summer and I'm not even sure about that). The highest I'd seen it climb to was slightly above 25°C.

I wouldn't say that I suffered from it by any means, as I even walked for a good hour in these conditions and barely started sweating, but we're clearly starting to exit my comfort zone here, and that's not a small thing given the extent to which I'm built for heat - those who know me can confirm this. I would still take that anytime over any temps below 18°C though, but still, I said recently in another thread that I hadn't found my "upper limit" for moisture appreciation yet, and fate proved me somehow wrong at least.

As I said, it seems tonight is an exceptionally sultry night in Singapore though, as, I repeat, I'd never seen a DP much above 25°C here, and usually around 23-24°C (which are perfect to me).

What do you think ? How would you guys feel in a 27°C dewpoint?

I'd probably faint from heat stroke; seriously.

Being British I'd just complain to the nearest person about how oppressive it is!

I've been comfortable in a 24°C dew point; sunset / nighttime; temperature was about the same with a breeze. The humidity was incredibly obvious. It's an odd feeling; you can sense the water.

Small increases in dew points at higher numbers make a large difference; I'd need it to be summer first before I can imagine a 27°C dew point but it sounds gross. Dew point is -11°C here, my lips are chapping.

You've found a personal threshold. Congratulations , This should further refine your knowledge of what your body is built for and its limits.

As for myself, in those conditions asphyxiation is a real threat, plus heat stroke. If I could not get inside within a few minutes, it would be a contest of which would make me pass out first: not being able to breathe in the thick humidity, or the heat stress. I've been in those sort of conditions, and there's a feeling of an elephant being on my chest in that sort of weather, and my oxygen intake was insufficient. Needless to say I went indoors immediately.

This is definitely a case study for different preferences and bodily builds. In pretty much identical conditions, where we may as well be standing next to each other, you would feel it as slightly sultry, whereas I would perceive potentially lethal levels of humidity.

Galveston, Texas usually records a few days with dew points in excess (or very close to) of 80*F during the hottest part of the summer...

Here is the data for August from the past 5 years (avg/max):

2011: 75/79 (10 days above 78)
2010: 75/79 (21 days above 78)
2009: 75/81 (2 days above 80, 14 days above 78)
2008: 75/81 (1 day above 80, 12 days above 78)
2007: 76/82 (5 days above 80, 21 days above 78)

Actually doesn't feel too bad if there's some wind, great weather for walking at night

If I had been there, I would have started sweating profusely within seconds. I probably would have had trouble breathing as well. Breathing hot, humid air feels like breathing in hot, wet cotton balls.

Just to make sure, did you experience those conditions at night (no sun) and with the temperature (low 80s) barely above the dew point? Otherwise, it's not a fair comparison.

Walking around at night might not be too bad. Sleeping would be nigh on impossible for me though.

Thanks though I cannot really say that I disliked it - what made me wish that the DP was a few degrees lower is the fact that I walked for an hour. Otherwise, that's perfectly fine (That's also obviously the opinion of many Singaporeans, which I saw spending a considerable amount of time outside tonight, eating, having drinks, chatting, etc. pretty like every other night).
I also wonder how spending the past year in Nice's sissy mild weather has somehow slightly moderated my ability to handle heat.
Perhaps I wouldn't even have noticed the 27°C DP last year when I was actually living in Singapore.
