The honest answer to when you should fly Houston to Colombo is mostly about weather and demand at the far end. On three years of daily observations at the arrival airport, Jan-Mar, Dec gives the most comfortable combination of temperature and rainfall in Colombo.

Weather in Colombo, month by month

Averages below come from three full years of daily readings at Colombo’s main airport, not from a seasonal generalisation. The warmest month is February (average high 33°C), the coolest is January (average low 23°C), and the wettest is November (584 mm).

Climate data: Open-Meteo reanalysis archive.

Packing for the gap: in February, Colombo averages 33°C against 21°C in Houston — about 12°C warmer, so plan for lighter clothing than you leave in.

Time difference and jet lag

Colombo runs 10.5 hours ahead of Houston. Travelling east is the harder direction to adjust to, so if the trip is short, an early departure that lands in daylight is worth more than a marginally cheaper overnight.

When fares move on this route

We publish observed fares for this route when we have them, and say nothing when we do not — there is no estimate on this page. What holds regardless of the route:

  • The travel date matters more than the booking date. Midweek departures are consistently cheaper than Friday and Sunday, because that is when demand actually sits.
  • Comfortable weather and low fares rarely coincide. Jan-Mar, Dec is the pleasant window in Colombo, which is also when more people want to go. The shoulder weeks either side of it are usually the better value.
  • School holidays and local events override everything. A festival or a public holiday at either end will outweigh any general booking rule.
  • Set an alert rather than watching manually. Fares move at hours you are not looking, and the useful booking window is weeks wide, not days.

Which day to fly

Midweek departures are consistently cheaper than Friday and Sunday on most routes, because that is where demand sits rather than because of any pricing trick. Where we have observed fares for Houston–Colombo, the weekday breakdown appears further down this page; where we do not, we leave it out rather than estimate it.
