Average daily temperatures in November
In November, daily temperatures in Wales usually hover between 43°F and 52°F (6°C to 11°C). The coast tends to stay a touch milder, but inland and mountainous spots get colder, especially at night, when temps drop to 39 to 43°F ( 3.9° 6.1°C). Frost isn't uncommon in these areas.
You'll also be looking at a lot of rain—about 5 inches (130mm) spread over 15-20 days. Cardiff usually gets around 4.7 inches (120mm), but if you're heading to the mountains, like Snowdonia, you might see over 8 inches (200mm).
Daylight is short—the sun rises around 7:30 AM, and it's already getting dark by 4:30 PM. If you're thinking of hitting the water, sea temperatures are about 54°F (12°C), which means you'll have to be brave to want to take a dip (and you'll want to pack a wetsuit). This is definitely a month where you'll want to layer-up.
What about the crowd and cost?
November is Wales' low season, which means fewer tourists — and with less demand means more savings. Hotel rates can drop by 30-40%, with plenty of winter specials and extended-stay deals. Attractions switch to reduced hours, but the upside? Minimal crowds—perfect for enjoying castles and museums at your own pace. Restaurants and bars tend to be quieter too.
If you're after better weather, aim for May to September. July and August bring the warmest days and longest evenings, but also higher prices and more tourists. For a sweet spot, check out May, June, or September—mild weather, fewer crowds, and fair prices.
