Would you let a young person climb a mountain in this weather?

[Zebradoodledo]

Opinion needed. 17yr old DD. Her workplace has had a hike up Snowden booked for the last few months for...... tomorrow. I've been keeping an eye on the weather situation and as most people are aware there has been an amber to red weather warning for extreme heat issued for Wednesday and Thursday. I spoke to DD earlier in the week about it, she the coach can't be rearranged for another day as they will lose the deposit for the coach but that they have all decided they will take it very slow and walk at the slowest persons speed and take lots of rest breaks
Last night I was looking at the weather and reports and hubby and I decided it wasn't safe..... she absolutely kicked off. Crying, palpitations, saying she wants to go blah blah blah. We tried to talk to her reasonably and showed her government advice about the weather, we were reasonable and gave all the evidence including that from hiking websites who advise against it and she was having absolutely none of it. She still wants to go. We ended up in a huge argument with her. She was sobbing and had a panic attack. We had to stop and we agreed to pick it up today and make the decision later. (She's not speaking to us this morning!!!)
I just don't know what to do?!?! She hates me right now, that's ok, I can take that. But even with all that here I am....still trying to find compromises even though every bone in my body says no!!!
Do I email the people she works with and ask for reassurances ? It's a social thing so not a work event.
She has 5litres of water she may need more, she's got to carry that though!!??! As well as everything else
She's never hiked like that before other than with DofE!!
She's bought all the right food (nutrition bars, couscous, dried fruit etc). Has sunblock and the right clothes.
She's argued the weather where we live is currently 'cloudy' but that's not to say tomorrow will be or will be in Wales. They're leaving at 6am so will arrive at 8am and it'll be walking through the main heat of the day.
At 17 she's still underage. We explained that we still have final say. Do I be the 'bad guy' or do I let her make her own decision? It's just a bloomin dangerous decision in my own humble opinion!!!! What are your thoughts?
Wishing for the toddler years ago...they seemed so much easier than parenting teenagers!!!!

Edit ,29 degrees.

I don't know what I would do, I wouldn't really want her to go but ifnit was that dangerous wouldn't they close it to hikers? Do they do that?

The higher they go the cooler it will be.

It could well be 10 degrees at the top. And windy.

I would let her go.

I think at 17 and working she should be allowed to decide. If it was DD14 I wouldn’t allow it.

Talking from Wales it’s bloody unbearably hot here with no air or breeze.

The forecast for that area tomorrow is a high of 23C and getting cooler as you climb. I wouldn't be troubled by that.

Which route are they taking? If it’s Crib Goch I’d say no due to the sheer difficulty of the ascent. Pyg Track or Miners is easier and manageable with rest stops.

Tomorrow (Wednesday): Mostly sunny and very warm. Valley temperatures will climb up to 27°C, while the summit will feel closer to 20°C. Winds around 10 to 15 mph.

I’d let her go and implored her to take a hat and layers to strip down to and put back on as she climbs higher where the temperature will be chilly. We‘ve had fog and 6° up there when the valley was basking in the summer heat.

Who is leading this tour? I’d ask them for reassurances.

You can’t close a mountain to hikers, no. I wouldn’t do it myself in this heat but I think it’s going to be hard to forbid a 17 year old. Her reaction is pretty extreme though to even having a conversation about it - what makes it so important to her?

Do I email the people she works with and ask for reassurances ? No, just no!!
It's low 20's in North Wales tomorrow morning, the higher up they get, the cooler it will be.
If she's taking 5 litres of water then she'll need electrolytes in it as well.

Temperature does drop with altitude, but by approx 6.5C per 1000m - so the top of Snowdon (not much over 1000m) could be around 19C if she's lucky..but most of the walk up will obviously be a lot warmer

The Met office forecast for snowdon summit is more like 20; obviously warmer lower.

tbh although it’s significantly warmer and sunnier than usual it’s probably ok for someone young and fit so long as they’re sensible and the group is willing to turn back if it starts to get too much for any of them.

Maybe they'll just have a nice trip to Snowdonia and do a low level walk and perhaps a river swim/paddle to cool off?

Given that half the young people probably won't turn up with anywhere near 5 litres of water so they'll be troubled with people running out of water in no time, so should be turning back or changing what they're doing, which they should be doing anyway - extreme weather should be in their risk assessment and they should be considering what they need to do for the trip to be safe and taking inexperienced people up a mountain walk in hot weather is high risk of heat stroke etc - if something goes wrong they'd likely be prosecuted.

But her reaction to you saying she shouldn't go is rather extreme. Is that normal for her?

Panic attacks seem extreme

Are the group prepared, will some of them be going up in flip flops and only have a small bottle of water with them?

I would advise against it tbh.
I live in sight of a very famous "hill" and the weather can change very rapidly bringing out the local search and rescue on a regular basis, summer and winter

Do I email the people she works with and ask for reassurances ?

Jesus Christ almighty, please don’t do this. Talk about mortification.

She’s 17, she’s in a group and they have someone who knows what they are doing leading them. It will get cooler as they go up. I’ve done hikes in hot countries without thinking about it and it has been fine.

Just focus your advice on the suncream, correct hat, correct boots (change of socks - she’ll sweat a bucket load), water in insulating bottle ect…

She'll be fine. Let her go! I'm a regular climber and have done warmer with no issues.

They taking the Rhyd Ddu path (sorry if I misspelt that) apparently

She's quite the drama queen!

@Gealach have I missed the bit where it says they have someone experienced?

posted twice

What sort of foolish workplace takes someone who has never hiked before up a path described as 'Some parts of Rhyd Ddu’s final section lead along a narrow and rocky path with steep slopes below. Extreme care must be taken on these parts' in any sort of weather?

Rhyd Ddu Path | Walks and Routes Eryri National Park

Let her go. As others have said tep drops with hight and if the heat isn't bothering her beyond being needing a drink and slower pace, she'll be fine!
Just ensure she has facto 50 suncream on exposed skin, a hat and plenty of water.
If you are worried about carrying water what about a water bladder/ blister? And a bottle with electrolytes solution - all ready available in any outdoor store!

From her reaction, she doesn’t sound sensible enough to turn back on finding the trek harder.

At 17 I think you’ve got to leave her to it. My DC is 17 and is away camping with their mates to celebrate the end of A levels that I consider most unwise not to mention unpleasant in this heat. I told them my opinion, but up to them, they will be 18 in 8 weeks - high time to start making their own decisions!

It doesnt seem to say so in the OP, I would be very wary 🤔

I would love to be up mountain for the next few days. They'll need an early start and to carry plenty of water, but it will be much nicer up there than down here.

I’ve found some photos to give you an idea of route and time: Trail

I‘ve done this route once with one of my kids and it’s not arduous. It’s one of the less common ones. I reckon she’ll be fine.

I‘d second the adding of electrolytes to water as she’ll be losing minerals in sweat which can’t be replaced by water only. Sunscreen and a hat are a must. Trust her to be fine. Implore her to download What3Words in case she does need assistance but she’ll be with her group and should be fine.

I’d be having a chat about her extreme reaction though - you’re her Mum and you care for her. You’re not some spoilsport who fancies an argument. Her reaction shows extreme immaturity and I would definitely address this with her at some point - possibly in a quiet chat when she returns.
