In April, Palma (Mallorca) experiences a beautiful spring transition, with average daytime temperatures hovering around 18°C to 20°C (64°F–68°F). While the days are often sunny and perfect for walking through the historic "Old Town" or visiting the Cathedral, the evenings can still be quite crisp, often dropping to 10°C (50°F), so a light jacket or sweater is essential. The sea temperature is usually around 15°C (59°F), which is generally too cold for swimming for most people, though the beaches are great for sunbathing on a windless day. April is considered the "shoulder season," meaning you’ll enjoy fewer crowds and lower prices than in the summer months. It is also a fantastic time for hikers and cyclists, as the inland Sierra de Tramuntana mountains are lush and green without the oppressive heat that arrives in July and August. You might encounter a few "spring showers," but they are usually short-lived and followed by clear blue skies.
