The Palestinian Territories share a Mediterranean climate with neighbouring Israel and Jordan, modulated by altitude. The West Bank ridge (Ramallah, Hebron, Bethlehem) is cooler than the coastal plain or the Jordan Valley; Jericho, well below sea level, is the warmest inhabited place on earth in summer.
Spring (March–May) is the best season everywhere. Wildflowers cover the hills, temperatures are mild, and Easter brings significant religious events in Bethlehem and the Old City of Jerusalem. Ramadan often falls in this window — fasting hours affect daily rhythms, but iftar meals can be a highlight if you're invited.
Autumn (September–November) is similarly pleasant: warm days, cool evenings, and the olive harvest in October across the West Bank.
Summer (June–August) is hot and dry. Jericho and the Dead Sea regularly hit 40°C; the hills are tolerable but the coast is humid.
Winter (December–February) is mild on the coast but cold and occasionally snowy in the hills. Bethlehem at Christmas is genuinely atmospheric.
Check current security advisories before planning. Movement between areas can be unpredictable; allow extra time at checkpoints.
