The higher you go the cooler it becomes. Every 100 meters in height the tempo drops by .6 of a degree. In Thailand terms, considering the height of the mountains there aint really anywhere to go to escape the heat. Here in Soppong the thermometer is readin 41 however at night it still dropped down to 17 last night which is perfect for sipping a few beers but not the best time for riding bikes unfortunately.
So since my house is 127met above sea level i can expect .6dec cooler,,,cant feel it though, Ray i got my garmin now and have to say it's fantastic,, highly recomended, can also connect to ear phones, so hear it inside helmet as well.
Get over it. Its that time of the year. We're all complaining about how hot it is now, soon we'll all be complaining about the Songkran fiasco and then we'll all be complaining about the rain and then in northern Lao/Chiang Mai we'll be complaining about the cold/fog. TIT/TIL.
If you're hot, buy a decent airconditioner and drink cold beer.
A bit of a rant but jeez its the tropics.
Go for a ride to Mae Hong Song, through the hills and doesn't matter if its hot, its still fun. Make it an adventure and do it on a Vespa.
I have Nuvi 310 what have bluetooth, but supports some whones only,,
got it english map installed from Bkk 26500thb, so far i have riven and really tryed to get loost in here(Ubon area) but just cant, have all the smallest rds and really clea instructions,, also tried in to my bike last night, suction stand is soo powerfull that i stick it to my speedo meter and drive to home 40Km with speed 103(according to GPS) and it's sticks like a clued to there.
