Like most of the Philippines, Siquijor runs on two broad seasons — dry and wet — with everything else being a matter of degree within them.
Dry Season (November–May) — The Safe Choice
This is the most reliable stretch for calm ferry crossings, sunny beach days, and predictable outdoor plans. If it's your first trip to the island and you'd rather not think about weather contingencies, aim for somewhere in this window.
Peak Season (December–February) — Coolest and Busiest
The coolest, most comfortable temperatures of the year, and also the busiest — both with international visitors and domestic travelers on holiday. Book your ferry and accommodation further ahead during this window, and expect resort rates to sit at their highest.
Shoulder Season (March–May) — Hot but Good Value
Reliably dry, but noticeably hotter and more humid than the December–February stretch. Crowds thin out and accommodation pricing tends to ease, making this a good window if you don't mind the heat in exchange for a quieter island and better rates.
Wet Season (June–October) — Lush, Cheaper, Riskier
Rain becomes more frequent and there's a higher chance of a typhoon affecting ferry schedules, though disruptions are typically short. In exchange, the island is at its greenest, crowds are thin, and prices drop. If your schedule is flexible enough to absorb a possible weather delay, this season has real upside for budget-conscious, less crowd-averse travelers.
Holy Week — A Unique Window
Siquijor's centuries-old reputation for traditional healers and herbal medicine draws its own crowd specifically around Holy Week, when practitioners are said to gather ingredients and perform rituals tied to the tradition. It's a genuinely unique cultural period to witness — but also one of the busier weeks on the island, so book well ahead if this is part of your interest in visiting.
Our Recommendation
For a first trip, the December–February window is the safest bet — reliable weather, comfortable temperatures, and no surprises. If you've been to the tropics before and would rather trade a little heat or rain risk for a quieter island and better rates, March–May and the early wet-season months (June–July) are both worth considering.
