While "best" is subjective, the coastal town of Jávea (Xàbia) on the Costa Blanca is frequently cited by the World Health Organization as having one of the most environmentally healthy microclimates in the world. It is sheltered by the Montgó massif, which protects the town from harsh northern winds while the sea regulates the temperature, resulting in over 320 days of sunshine and an average annual temperature of 20°C. Another strong contender is Marbella on the Costa del Sol; its proximity to the Sierra Blanca mountains creates a unique "rain shadow" effect, keeping summers cooler and winters warmer than inland Andalusia. For those who prefer lush greenery without the typical northern cold, the Costa Tropical in Granada (specifically Almuñécar) offers a rare subtropical microclimate in Europe, allowing for the growth of exotic fruits like mangoes and avocados due to the protection of the Sierra Nevada mountains against the cold polar air.
