Finished April with an average #AQI of 119, better than average (167). My records remind me that the AQI for 1st May last year was 229 - unlikely today 😊, I do think we can congratulate and thank the policy & @ChiangraiGov for a large part of that. #NorthThailand#AirPollution
Hottest day of the year yesterday, 41.6C, AQI back into Unhealthy ave over a 24hr period &, with the joined up thinking common to local authorities across the globe, the PEA chose yesterday to shut the power off all afternoon for maintenance. #NorthThailand#AirPollution#Crisis
I’m not going to declare the end of the smoky season, there’s usually a sting in the tail, but with 57mm rain yesterday I think my garden watering duties might be over for a year. #NorthThailand#Rainfall#Mekong#Watershed
Already more rain than last April but still 48mm needed to make average. The first ‘green’ AQI day for us since 16th December but so far a much better #Smoke Season, @ChiangraiGov’s total #BurningBan has been successful in minimising #NorthThailand’s #AirPollution#Crisis
The heavily forecast ‘rain all night’ did not occur, much like last week. But we did get enough of a shower to justify (almost) scraping the panels this morning. The #AQI is in a better place at least, 107 this morning. #NorthThailand#Mekong#Watershed#Rainfall
0.5mm finally fell at home last night, not enough to stop me watering the garden but at least off the mark for April. It is a 105mm month so there should be some to come. #Rainfall#NorthThailand#Mekong#Watershed
AQI so far this month is 175 vs full month average 167 BUT rains tend to come later in the month so that would be expected to drop #NorthThailand#AirPollution still a #Crisis but better than previous years.
Synchronicity! #Cycad & #BabyCycad threw out, guessing April 1st? A week earlier than last year, not sure what that means but #Phenology for anyone who might.
That morning after the rain I kind of joked about the pendulum swinging back, despite years of experience didn’t really believe but… yep, rain doesn’t clean the air, weather patterns push smoke away. As SOON as the pattern changes the smoke comes back. #AirPollution#Crisis
Our Southern & Western neighbours ruining it for all - and with no publicity around punishment for offenders or authorities down there how long before #ChiangRai folks get fed up breathing others smoke when their own would be fresher? #NorthThailand#AirPollution#Crisis
It didn’t take long for the pendulum to switch back. The weather system that pushed the smoke away has already slightly reversed & the bad air is coming back. Best we can hope for is a slow return:

An 11 hour #AQI red period yesterday but not enough to sway the day, 142 average. February is a 114 average month (last 4 years) but currently sitting at 130. #NorthThailand#AirPollution#Crisis
Ave #AQI at my house for January was 96 vs an average of 89, 2nd worst recorded (‘21 - AQI=114). A rare no rain Jan (ave = 24mm) but given the #AirPollution hammering Bangkok took we can still say we were lucky with the weather, usually at least some of that would be held here.
The weather changed &, as predicted, dirty air is back, 117 #AQI yesterday - worse in Bangkok so that should help the pressure continue. May have been a fluke but drove to town yesterday afternoon & saw no fires - almost unheard of. #NorthThailand#AirPollution#Crisis
