The best time to visit Mallorca as a cyclist is typically from February to May and from September to November. During these months, the weather is mild and pleasant, with temperatures ranging from around 15°C to 25°C, making it comfortable for cycling.

During the peak summer months of June to August, temperatures can soar, and the island can become crowded with tourists. This can make cycling more challenging, as the roads and popular cycling routes can be busy with traffic.

In the winter months of December and January, temperatures can drop, and the weather can be more unpredictable, with a higher chance of rain and wind. However, the island can still be a great destination for cyclists during these months, especially for those looking for a quieter and more peaceful experience.

Ultimately, the best time to visit Mallorca as a cyclist depends on your personal preferences and goals. Whether you’re looking for challenging climbs or leisurely rides along the coast, Mallorca offers a wide range of cycling experiences throughout the year.
