When planning your flight to Colombo, it is important to be aware that some months are not as ideal as others. Specifically, the months of April, May, or June could carry a higher chance of rain, as Colombo sees up to 5.1 inches (130 mm) or more. There are still things to do in Colombo even when it's raining, but be aware that rain is highly probable in the area. For those looking to get out of the rain and do a little shopping, check out Pettah Market.
If your plan is to spend time at Galle Face Green while visiting Colombo, momondo recommends you plan your trip for January or February when the temperatures are typically higher and the chance of rain is low.
Currently, Sri Lanka travel restrictions include travel to Colombo. Sri Lanka has closed all airports. Bandaranaike International Airport (CMB) is still accepting certain special categories of flights including emergency diversion flights, humanitarian aid flights, freighter operations, and technical landings. All arriving travellers must submit completed Health Declaration Forms to public health inspectors or other authorised officials. The maximum allowed transit time at CMB is 12 hours. Passengers must have a confirmed onward connection. Airline crew must self-quarantine at the location mentioned in the Health Declaration Form and have meals only through in-room dining until they operate their next flight. Visas and ETAs issued by Sri Lanka have been invalidated. If you are planning to travel to Colombo at this time, it is recommended that you stay up to date on current restrictions and follow proper safety measures while in public.
