Bangkok and Hanoi
The verdict for April
Songkran and serious heat
+Songkran transforms Bangkok into one of the world's most energetic celebrations.
–Extremely hot, with Songkran creating major crowds and disruption if you are not there for the festival.
Songkran is a genuine once-a-year spectacle.
Warm, lively and highly walkable
+Warm weather arrives before the heaviest summer rain and humidity.
–Heat and rain both build toward May, especially late in the month.
April is warm without peak-summer extremes and remains strong for sightseeing.
Scores and crowd levels are my own judgement; temperatures are monthly averages. Higher scores are better: quieter, cheaper and more pleasant.
Another month
