Damp laundry in the morning heat

This hazy warm morning  at 7:30 am while checking my still damp laundry (high humidity at dawn) I measured a wet bulb temp of 28.2C (82F), as high as I can recall here in Bangkok. The daily pattern has been the same for a week now, typical hot season weather. Humid dawns with air, wet bulb, and dew point temperatures converging at about 27-28C, followed by warming  to about 38C (100F) midafternoon. Increasing relief from southerly breezes off the Gulf of Siam throughout the day and evening, offsetting to some degree the rising temperature. Much like late summer Gulf Coast Texas weather. Greater afternoon discomfort has more to do with glare and radiant heat from hot streets and sidewalks  than 100F air temperature. Average daily temps about 33C. Checking back over the years records I find that it was a bit warmer in the early 1990s, with daily average temps sometimes 34 or above, hence whatever people want to think we are not experiencing anything extraordinary so far this year. For the last week, check out this chart from Weather Underground (note the superelevated bump in dew point this morning):
