    What's the weather like in Sri Lanka in December?

    Sri Lanka’s in the Indian Ocean around 30km off the southeast coast of India. It has a tropical climate with warm weather all year round and two monsoon seasons. The northeast monsoon’s from October to February and the southwest’s from May to August. December’s in the northeast monsoon so you'll get most rain in the north and east at this time. The south west’s generally the wettest region while you'll be driest on the northwest and southeast coasts.

There’s 166mm of rain over ten days, and you can expect 12 hours of daylight with seven hours of sunshine each day. UV levels will be extremely high so don't forget your sun cream.
