What you gain in May
- ↑Hydrangea peak season begins in late May on São Miguel and Faial: the volcanic roads disappear between walls of blue, pink, and white Hortensia so dense that the landscape is defined by them; the Sete Cidades crater lake rim road and the Faial cliffs above Capelo are the most spectacular; the combination of vivid blue flowers, black lava stone, and the turquoise lake surface below is the defining Azorean landscape image
- ↑May whale watching is outstanding — blue whales and fin whales are reliably present before they depart for northern feeding grounds, sperm whales remain year-round, and bottlenose and common dolphins are visible on nearly every trip; the Azores Whale Watch operators in Lajes do Pico and Madalena use traditional land-based whale spotting techniques inherited from the whaling era
- ↑Pico mountain summit hiking in May: the weather window for a clear summit ascent (2,351m, the highest point in Portugal) is at its widest in May–June; a 4–5 hour round trip from the base station requires no technical equipment and delivers a volcanic summit view above the clouds with the remaining islands visible 50–100km in every direction
What you sacrifice
- ↓May is the beginning of the European tourist season — Ponta Delgada on São Miguel sees a meaningful increase in visitors from Lisbon and Northern Europe; the best guided whale watch operators, the most popular trailheads (Sete Cidades, Lagoa do Fogo), and the standout accommodation start booking out at the short end
- ↓Rainfall is still possible (50mm) — the Azores Atlantic location means even the best months can deliver a wet day or two; the Furnas caldeira valley and the Lagoa do Fogo crater lake are sometimes in cloud even in May
- ↓Senhor Santo Cristo festival crowds in Ponta Delgada (if falling in May) can temporarily pack the city's infrastructure beyond capacity — accommodation within 5km of the city centre is essentially unavailable at any price during the festival weekend
