“Only 7°C better for 2h 10m on a plane. That’s slightly warmer rain.”
- 7°C warmer than Ireland’s usual 14°C
- 6 hours of sun a day, against 3
- Short hop: 2h 10m 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.
“About 2h 10m, so it's over before the film gets going.”

The honest airport tips
- Shannon is usually quick through security, but give yourself time on busy summer mornings.
- US flights clear US immigration at Shannon before take-off, so you land as a local. Have your passport handy and your patience ready.
- Book parking online before you go; it's cheaper than paying at the barrier.
