Weather in Bangkok in January
January in Bangkok is a hot month. Plan the serious walking for morning. The rest of the day wants shade and a slower pace.
In Thailand, this is how Bangkok actually wears January, not how a country centroid would. Compared with April and December, January sits in the middle of Bangkok's year.

What to expect
Daytime
Hot days in Bangkok. Ruins, markets and hills are a morning job. Midday sightseeing is how people remember January for the wrong reason.
Nights stay warm. Air-con, if you can get it, is part of the brief. A jumper for January in Bangkok is almost always a waste of bag space.
Rain
Rain is not the story in Bangkok in January. Pack for sun. A shower would be news, not a plan.
Do not build the trip around weather windows. Build it around shade if it is hot, and around getting outside if it is not.
Evening
Evenings stay warm.
