Seasonal divisions in the Isaan – as far as I consider them to be – probably do not conform to what is taught in school or understood by most Thais, but are most likely pretty close:
n Spring: February thru April (the hottest three months of the year)
n Summer: May thru September (the Monsoon season of substantial rain)
n Fall: October thru November (harvest time, air cooling)
n Winter: December thru January (the coolest two months)
This year, the cooling and drop-off in rain began in mid-September. You could definitely feel the cool breeze in the afternoons. We did not need the fan on all night. As for the rain, these became scattered, with less and less intensive downpours.
Now, in October, my wife and I sleep with a blanket over us – if not right away, at least within an hour or two when, if we have turned the fan on, it is shut down for the remainder of the night.
In the morning, ground fog lingers and a hot water shower is the order of the day, when, usually, a cold water shower feels better most of the year.
The day temps are now rather comfortable and I’m not sweating all the time unless I’m doing physical labor. The numbers of nyoong (mosquitoes) seem to be lessening, too, probably due to a combination of cool nights and less rain.
Thip keeps saying the rain will end soon. If that is the case, I can see why the King has emphasized his “New Theory” and a “Self-Sufficient Economy” for
Thailand; where he has encouraged
Thais to build pools of water at higher levels from the rice paddies, and the
construction of and tapping into local klongs (canals).
(shot taken at our largest rice farm's pool, when we donated a fallen tree to our local temple early in 2013; note Love Shack II [aka "Bann Monkom"] in the background with motorcycles and tuk-tuk parked next to it.)
I asked my wife about the pools at all the rice fields that do not have access to the klongs (about 90% of them) and she confirmed that most all of them had been dug and put into use within her lifetime of 40 years.
Imagine how less sure it was, in the past, to bring in a successful harvest if you only had the Monsoons to rely on. I mean, there’s another two months to go before our family harvests the rice on our two rice farms. If the Monsoon tap is soon to shut, we’re gonna need all the water we can get from the pools to keep the rice stalks alive and healthy. At our larger farm, we have also dug a well and installed a pump, so no problem there!
