Colder than home. Bring the good coat.

Worth the bother?

4/10 Think about it.

“Only 8°C better. Ask yourself if it’s the weather or the trip you’re after.”

8°C warmer than Ireland’s usual 14°C
3 rainy days a month, against Ireland’s 12
8 hours of sun a day, against 3
Long haul: 11h 05m direct

How we work this out

Worth the bother is worked out from the same facts every time: how much warmer, drier and sunnier it usually is there than in Ireland that month, how long the flight is, how good the place is, whether something’s on and, when we have enough fares for the route, whether the month is unusually dear or cheap. We use the usual weather for the month so one freak day can’t swing it. When you tell us what you’re after (snow, Christmas markets, walking and so on), the weather part asks how well the usual weather fits that, not just how warm it is. Nobody can pay to change a score, and plenty of places score low on purpose.

The Bottom Line

Who should go: Best for city-break fans.
Who shouldn’t: Skip it if you won’t sit through a long flight or you’re watching the budget.
How long: Give it a week or more. The flight alone eats a day.
Worth the money?: Only on a good fare. It isn’t cheap.
Would we go?: Not this month. Try another.

The honest verdict

Is San Francisco worth it?
