The best time to go to Rrushkull is during the shoulder seasons of May, June, September, and early October.
These months offer pleasant weather, with warm temperatures great for enjoying the beaches and outdoor activities without the intense heat and larger crowds of the peak summer months. You'll find the sea warm enough for swimming, and the local establishments will be fully open.
For those looking for the warmest temperatures and a lively option, July and August are also good options. However, expect higher prices, more people, and very hot weather, with temperatures often exceeding 30°C.
If you prefer a quieter trip and don't mind cooler weather, late April or late October can still be lovely, though some seasonal businesses might be starting to close or haven't fully opened yet.
