TOP 3 DEALS IN MONTENEGRO

The climate of Montenegro is Mediterranean on the coast, with heavy rains from September to April, while moving inland it becomes progressively more continental, with colder winters, also due to the higher altitude. 

The best time to visit Montenegro is from May to September. 
On the coast; the climate is mild but rainy in autumn and winter, while in summer it's hot and sunny, though tempered by the breeze. Winter is mild, with average temperatures in January around 7/8 °C (45/46 °F). Cold air masses of Russian origin may reach the coast, bringing a dry, down-slope wind which descends from the mountains and lowers the temperature but generally do not bring snow, except in limited areas where the wind is channelled through mountain passes instead of descending from the ridge. The Bay of Kotor is sheltered and mild, but in the cold season the temperature drops suddenly when the Bura blows - a cold wind coming from the interior. In the capital Podgorica, located in the plains but at some distance from the sea, the climate is still quite mild, but a little more continental than on the coast so that winter is a bit cold. The average in January is 5 °C (41 °F), while summer is hot and sunny, often with torrid days - heavy rains are possible from October to March. 
On the coast, summer is a good season for a beach holiday, especially in July and August. The weather is sunny and hot, but tempered by breezes. 
In Podgorica, summer can be uncomfortably hot, where the temperature can reach 40 °C (104 °F), in July and August, therefore it's better to choose May, the first half of June, and September. 
In mountainous areas, summer is the best season. The sun often shines, even though there's some chance of thunderstorms in the afternoons.
