The best time to go to Ghadames is during the shoulder seasons of spring (March to May) and autumn (September to November) to avoid the extreme desert temperatures.
During these months, the weather is pleasantly warm, making it ideal for exploring the ancient city and its surroundings. You'll find daytime temperatures comfortable for walking through the narrow, covered alleys of the Old Town and visiting historical sites. These periods also offer a better chance to experience local festivals, which often take place when the weather is more agreeable.
For those looking to focus on historical exploration and cultural understanding, these milder months provide the most comfortable conditions.
