Flights from San Francisco to Dublin

How long is the flight from San Francisco to Dublin?

The great-circle distance from San Francisco International (SFO) to Dublin is 5,088 miles. Flown nonstop, that works out at roughly 9h 44m in the air, including taxi time at both ends.

Expect the return leg to differ. Flying eastbound on the way out, you are pushed along by the jet stream, so the outbound and inbound block times on this route typically differ by around 45 minutes. Airlines schedule for this — it is not a delay.

Can you fly San Francisco to Dublin nonstop?

Nonstop exists, but not from everywhere

At this range nonstop service is flown only on flagship routes out of the largest hubs. From most US cities you will connect once, typically through a European or Gulf hub, and the connecting fare is frequently several hundred dollars below the nonstop.

When to book

May and June are the sweet spot. Days are long (sunset after 9:30pm in June), temperatures reach the high 50s to low 70s°F, and the summer tourist surge hasn't fully arrived. September and early October are also excellent — still mild, crowds thin out, and accommodation prices drop 20–30% from August peaks.

March 17 (St. Patrick's Day) brings an enormous festival and parade that's genuinely fun — but accommodation triples in price and books out months ahead. July and August are the warmest months but also the busiest; expect queues at major attractions and premium hotel rates. Winter (November–February) is cold, dark, and wet, but the city is alive and locals are indoors — this is when pub culture is at its most authentic.

Landing in Dublin

You lose 8 hours flying out. Eastbound is the harder direction to adjust to, because you are asking your body to fall asleep earlier than it wants to. Book an arrival that lets you stay up until local evening rather than napping.
