Averaged from the last five years of April readings — a guide to what to expect, not a forecast for a particular sailing.
Santorini is a crescent-shaped caldera left behind by one of the largest volcanic eruptions in recorded history. The blue-domed churches and whitewashed houses of Oia and Fira sit on cliffs high above the water. Cruise ships anchor inside the caldera and tender passengers ashore to reach the black-sand beaches, the Bronze Age ruins at Akrotiri, and the island's restaurants.
Santorini in April offers pleasant temperatures, with highs around 66°F and comfortable lows near 56°F. Rain is uncommon, with only about 5 rainy days expected across the month, ideal for beach days and shore excursions. Pleasant with fewer tourists
Crowds are moderate in April, making it a good balance between availability and weather. Lightweight layers work well: a light cardigan for evenings on deck and breathable tops for port days cover most conditions.
