Warmer than London, but still spring weather

Marmaris averages 6.3°C warmer by day than London in March, where the typical high is 10.5°C. That is a useful improvement for spending time outdoors, but not a reason to pack only summer clothes. The warmest days can reach 20°C or more, making a light top comfortable when the sun is out. Keep another layer handy for shade and later in the day. Nights can fall to 6.6°C or below at the colder end, so trousers and a proper jacket earn their place in your bag. March is better suited to travellers who enjoy mild afternoons than those seeking reliable heat.

Expect sunshine with a real risk of rain

March brings about 6.7 hours of sunshine a day within 11.7 hours of daylight, so there is scope for pleasant outdoor time. The catch is that it is still a wet month, with about 9 rainy days. Do not read the sunshine average as a promise of clear skies throughout your stay. A waterproof jacket and shoes that cope with wet pavements are more useful than relying on an umbrella alone. Keep your outdoor plans movable and use brighter spells when they arrive. This is a reasonable choice if showers will not spoil your break, but less suitable if guaranteed dry weather is the priority.

Treat the coast as somewhere to walk, not swim

The sea is cold in March, averaging 16.6°C, with the usual year-to-year range staying between 16°C and 17°C. That makes a swimming-led holiday a poor fit, even when an afternoon feels pleasantly warm on land. You may enjoy sitting by the water in sunshine, but bring a layer rather than assuming beachwear will be enough. With daytime temperatures generally mild, there is less reason to organise everything around avoiding midday heat; instead, let sunshine and rain guide your timing. Choose March for walking and a change from cooler UK weather, and look to a different month if warm-water swimming is central to the trip.
