Yes, Majorca (Mallorca) is an excellent choice for the October half term in 2026, offering a "mild summer" experience without the oppressive heat or swarming crowds of July. Daytime temperatures hover around 22°C to 24°C, which is perfect for cycling in the Tramuntana mountains or exploring the historic streets of Palma. The sea remains warm enough for swimming, typically around 22°C, though you should expect a few more scattered rain showers than in the summer months. Most seasonal resorts and waterparks remain open until the end of October before closing for the winter. It is an ideal time for families who want to avoid the "peak season" prices of July but still want enough sunshine to eat outdoors. Note that evenings can cool down to 14°C, so a light jacket is necessary for dinner by the coast.
