Booking choice: The Cliffs of Moher rail tour, from $185 per person. Check dates Tour details
The official site's own warning is that the cliffs can be cloaked in fog one minute and basking in sunshine the next. On a day trip you cannot choose the hour you arrive, so it helps to know what fog and wind mean for the visit, and what you can control: your clothes and your booking terms.
The quick answer
Weather at the cliffs is highly unpredictable, and fog can lift quickly, so a misty start does not mean a lost visit. In a Yellow wind warning take extra care; in an Orange warning the site is considered too hazardous to visit; in a Red warning it closes. Wear a good rain jacket and walking boots. Peak hours are 11 AM to 4 PM. Tours cancel free up to 24 hours before, and operators can cancel for bad weather.
What is the weather like at the Cliffs of Moher?
Changeable: the official site calls it highly unpredictable, and the wind is usually much stronger at the cliffs than the general forecast suggests.
Expect rain, sun and wind on the same day in any season. Check the Met Éireann forecast at met.ie the day before and the morning of your trip, and plan your clothes for the worst of it.
Weather looks fine? The rail tour cancels free up to 24 hours before if it turns.
Check dates for the Cliffs of Moher rail tourWhat happens if it is foggy?
Not necessarily: fog can hide the cliffs completely and then lift quickly, so give it time.
Waiting in the visitor centre for a while can help, and two hours on site, as on the rail tour, gives the weather a chance to change. Fog is part of the experience here; see Cliffs of Moher tickets for what the ticket covers.
What do the wind warnings mean?
The cliffs follow the national wind warnings: Yellow means extra caution, Orange means too hazardous to visit, and Red means the centre closes and the site is evacuated.
| Warning | What it means at the cliffs |
|---|---|
| Yellow | Open, but take extra caution near the edge and on the paths |
| Orange | Considered too hazardous to visit |
| Red | Visitor centre closed and the site evacuated |
Are tours cancelled in bad weather?
Sometimes: the operators can cancel for bad weather, and the boat and island legs of some tours depend on the sea.
All the tours here cancel free up to 24 hours before, except the 3-day rail tour (free up to 6 days before). If the operator calls the day off for poor weather, you get a different date or a full refund. One rail tour guest wrote that strong wind stopped them going to the top. The boat cruise on the caves day and the cliffs cruise on the Galway day only run when the sea allows.
Want flexible terms? The rail tour cancels free up to 24 hours before, so you can watch the forecast.
Explore the Cliffs of Moher rail tour Tour detailsWhat should you wear to the Cliffs of Moher?
A good rain jacket and walking boots, as the official site advises, plus warm layers, a hat and gloves outside summer.
- Waterproof jacket with a hood
- Walking boots or shoes with grip
- A warm layer, even in summer
- Hat and gloves for the wind
- A dry pair of socks for the long trip home
- Snacks and a card or euros, since meals on the tours are at your own expense
What time of day is quietest?
Before 11 AM or after 4 PM: the official site names 11 AM to 4 PM as peak hours.
Day trips from Dublin leave around 7 AM and need several hours to reach Clare, so they usually arrive in the busy middle of the day. If quiet paths matter to you, stay in the west and visit early or in the long summer evenings, when the site is open until 9 PM.
Fine with the midday crowds? The rail tour gives you two hours on site, entry included.
Check dates for the Cliffs of Moher rail tourWhen in the year should you go?
Any month works, but opening hours are longest from May to August (until 9 PM) and shortest from November to February (until 5 PM).
The weather is unpredictable in every season, so pick your dates for other reasons and pack for rain either way. If you are bringing children, read the Cliffs of Moher with kids for wind and safety tips.
Can you keep your plans flexible?
Yes: book a tour with free cancellation and decide closer to the day, or stay in Galway and visit from there.
From Galway, a 10-hour day leaves Merchants Road at 9 AM, crosses to Inisheer and gives you an hour on top at the cliffs, with a cruise below them when the sea allows.
Staying in Galway? Inisheer, the cliffs from the water when the sea allows, and an hour on top.
