Heraklion in May

April through June gives you the best weather without the summer crowds. Temperatures sit comfortably between 20-25°C, the sea warms up enough for swimming by May, and hotel prices stay reasonable. Easter week gets busy with Greek families, but the atmosphere becomes festive rather than overwhelming. September and October extend the sweet spot. The sea reaches its warmest temperatures, the summer heat breaks, and restaurant terraces become pleasant again for evening meals. October can bring occasional rain, but it usually clears quickly. July and August bring 35°C heat and cruise ship crowds that pack the archaeological sites by 9 AM. If you're coming in summer, plan indoor activities for midday and save the beach time for early morning or late afternoon. Hotel prices double, and reservations become essential. Winter sees most tourist restaurants close, but local life continues. Temperatures rarely drop below 10°C, and you'll have the museums and ancient sites mostly to yourself. The tradeoff: shorter days and choppy seas that make beach time unlikely.
