Daytime and night-time in March
The typical March day in Halkidiki peaks at 13.2°C, but that is an average: the warmest 10% of days reach 17.0°C or more. Days over 25°C are rare. Nights average 8.1°C; one night in ten drops to 4.7°C or lower, so pack a layer for evenings - it is genuinely cool after dark. Between 1991 and 2020 the hottest March day here reached 26.4°C (2001-03-26) and the coldest night -1.8°C (2003-03-24).

Wet (more than 8 rainy days): about 9 days with 1 mm or more, 58 mm in total. Year to year it varies a lot - the wettest March was 2015 with 159 mm, the driest 2001 with 10 mm. Humidity averages 73%.

Expect layers rather than reliable warmth
A mild afternoon can feel pleasant for walking, but March is not a month to plan around heat. The warmer days reach 17°C or more, while the colder nights can fall to 4.7°C or below. Bring layers you can adjust through the day, with a warm outer layer for evenings and a waterproof jacket for wet spells. Shoes you are comfortable wearing in rain make more sense than packing mainly for the beach. The catch is that mild conditions are not guaranteed throughout your stay. This month suits travellers happy to adapt their outdoor plans, rather than those who need reliably warm afternoons to make the trip worthwhile.
Useful daylight, but a cold sea
There is about 5.8 hours of sunshine within 11.7 hours of daylight, so there is scope for time outdoors without expecting sunshine all day. Keep the brighter spells for walks by the water and leave room to change plans when rain arrives. The sea averages 13.5°C, which is cold rather than simply refreshing; a holiday built around relaxed swimming is a poor fit. If swimming matters to you, do not mistake a mild afternoon for warm water. March makes more sense for travellers who enjoy being beside the sea without needing to get in, and who are comfortable wearing a jacket for part of the day.
