Important Weather Considerations:
The Gulf Stream Effect:
Ireland’s climate is moderated by the Gulf Stream, keeping winters milder than other countries at similar latitudes. This means:
- Snow is relatively rare, especially at sea level
- Temperatures rarely drop below freezing
- Coastal areas tend to be warmer in winter than inland regions
Regional Variations:
- West Coast: Generally wetter and windier
- East Coast: Usually drier with more stable weather
- Midlands: Greater temperature extremes
- Mountains: Cooler temperatures and more precipitation
Packing Tips:
- Layers are essential year-round
- Waterproof jacket is a must
- Umbrella (though wind may make these impractical)
- Sturdy, waterproof walking shoes
- Sunscreen (even in winter – the UV index can be high)
Local Weather Wisdom:
- “If you can see the mountains, it’s going to rain. If you can’t see them, it’s raining.”
- Weather can change rapidly – always be prepared
- Coastal areas often experience “four seasons in one day”
- Local forecasts are generally accurate for 24-48 hours
