My husband and son will be visiting Thailand in late March. They will spend a day or two in Bangkok and the rest of the time will be in Chang Rai and Chang Mai.

Can anyone give me an idea of what the weather will be like? Rainy? Cold? Hot?

Also, my son will be 13. Any suggestions for things "not to miss?"

By the end of March it is starting to warm up here, it will be over 30 most days and we will have packed the duvets away and will be sleeping in air conditioning. It should be dry; the rains don?t really start until May.

For a thirteen year old, I would think some rafting and an elephant ride, they can be combined and take about half a day. Maybe also a visit to a snake farm with a show.

There is the increasingly standard adventure stuff about; bungee jumping, go-carting, balloon rides and microlights.

tangata---you keep referring to the duvets...i can't believe it ever gets that cold in CM???? exactly how cold would you expect it to be? i have been there in december and february and found it to be routinely hot....

The blood must be getting thin! Overnight temperatures at the moment are about 16 degrees, probably one or two degrees cooler where we live on the slopes of Doi Suthep. Overnight temperatures in December and January are often in single figures.

At this time of the year, we sleep with only mosquito screens across the windows and sliding doors, so we are experiencing outside temperatures. It makes a nice change from sleeping in an air conditioned room. When we do use air conditioning, we set the thermostat at 24 degrees. So a drop of eight degrees, to 16, is noticeable.

Up in the hills sub zero overnight temperatures are quite common.

Despite this, daytime temperatures are always relatively high; the lowest we get to is probably 22 or 23 degrees.

we would use a duvet when the teps are 60F or less...i never quite know the proper conversion, but i think your temps are above that??

16 degrees is equivalent to 60.8 F, 24 degrees to 75.2, so we have a drop of about 14.4 F.

Our coolest daytime temperatures are around 72 F and I would expect our coldest night to be about 46 F. So well into your duvet range.

at 46F i let my feet hang out the bottom...
