England in 14 days April 14-27

The truth is nobody knows. The UK has a maritime climate so it's very difficult to provide accurate long term forecasts, or even short term, and there isn't the predictability of a continental climate. It could be warm, it could be wet or it could even be snowing. Your best bet is to wait as close to your departure as possible before packing and be guided by the forecast from the UK met office www.metoffice.gov.uk.

Hope for the best, prepare for the worst! This means layers, possibly a down/insulated jacket and definitely a waterproof jacket. I don’t know about the Eddie Bauer trousers, but I’d have an alternative to jeans/denim if it does happen to rain. Wet denim is miserable stuff!

All we can tell you this far out is that there will be weather. What sort is not predictable. Best case scenario is it will be bright and sunny, if not boiling hot. But as I always say weather is the one thing you can’t book ahead of your trip, anywhere!

Have a great trip!

It could be anything but there’ll be a more accurate forecast closer to the time. You’ll definitely need layers and waterproofs. Even if no rain is forecast it can still rain.

For a mid-February to mid-March trip to Rome and Naples last year, I took a pair of Eddie Bauer fleece-lined pants. I'm very cold-natured, and those pants were great. I often wore merino wool long johns underneath them since it was quite chilly in the morning (often under 40F) and after the sun went down. I found I wasn't uncomfortably warm in the middle of the day even when it got up to about 60F. YMMV on that score, and I don't know how hot it might get in England in late April.

I like the 97% nylon pants sold by Eddie Bauer and others, because they do a fairly good job of shedding rain. If I had a trip solely to England in April, I might be tempted to pack real rain pants. I've never done that because I don't want to cart such things around through an entire trip when most of my time will be spent in a less-wet environment.

Above the waist I am often comfortable with just a long-sleeved cotton top, a fleece jacket and a rain jacket/windbreaker, but I always pack one merino wool underlayer. I used the merino layer on multiple occasions during my trip to Scotland in July 2019.

The Brits have spoken, and they know best what to expect, as well as anyone can predict.
As JC said, the truth is nobody knows for sure.

We were on this tour from mid April til end of April in 2018.
At that time, we were fine with medium weight clothing in Bath, the Cotswolds, Blenheim, and Wales. In the Lake District, we needed a waterproof (spitting rain, plus wind) parka, turtleneck sweater, fleece-lined pants or heavy jeans..
It got colder still when we arrived at Hadrians Wall. The wind blew gale-force from the north....cold.....some members of our tour had to go back and sit inside the bus while others walked around Vindolanda.

Arriving in York, it was chilly with pouring rain.
Fortunately, I had packed a waterproof jacket with a hood.
When we arrived in London, we stepped off the train to bright sunshine, clear blue skies, and were back to needing only medium weight clothing.
It was not hot weather; no shorts or sandals needed, for sure! Just warm-ish.
But we were back to jeans (or guide pro pants from Eddie Bauer), polo shirt, plus a jacket for walking around and the final group dinner.

When you're there, the weather could be like this for your tour, or it could be completely different.
So, my post may or may not be helpful.
Hopefully it is.

You Americans appear to use the word ‘pants’ for what we Brit's refer to as ’trousers'. When we refer to ‘pants’ we mean underpants. That being so, what do the Americans call underpants?

The problem is as well that we’re used to living in a fairly cool environment so our perception of the weather is different. So I can tell you it will be mild and even quite pleasant but you will feel it as uncomfortably cold.

I think I run cold but I can’t imagine ever wearing thermals in April like a poster above needed to on a trip here. And on the other side of it, I’m going to Spain next week and I know my kids will be in shorts and t shirts while the locals are dressed for winter!

James,

Brits say "trousers"--Americans say: pants, slacks, bottoms, trousers (used occasionally by the older generation like my grandfather).

Brits say "pants"--Americans say: underpants, undies, underwear, briefs, (ladies) panties.

I’m 71 and I’ve never worn thermal clothing of any sort at home, at any time of the year.

We generally call underpants “underpants”..
