You need to be suitably dressed for the weather that is likely to be experienced at the summit not just at the car park! That doesn’t mean you have to wear your waterproofs in the sunshine, like many still do walking up Snowdon.
Overheating can be a serious problem in the summer, as hyperthermia can be in Winter. You need to make sure that you are wearing non-cotton trousers and tops. Jeans and similar heavy cotton garments are e big no-no as they do not cope well if they become wet.
Modern synthetic garments dry quickly and don’t keep sweat trapped like cotton. Merino wool is even better, if you can afford it! A decent fleece, jumper, or synthetic/down insulated jacket should be carried to wear if it gets cooler or when you stop.
On top of all this, you’ll need a decent waterproof jacket and leggings. Another item I find invaluable is a thin windproof smock. This weighs barely anything, and is often all you need in summer over a t-shirt to cut out the cooling wind. If you wear your waterproof as a windproof, then you’ll more likely than not end up getting damp from sweat as breathable fabrics are not 100% breathable. To top it off, a pair of thin gloves and a hat may even be needed in summer.
On your feet, boots are the standard item of gear but some find these heavy in the summer and wear trail shoes. However, it is recommended that you wear walking boots that you’re comfortable with and that you’ve worn a few times already. Half way up Snowdon is no time to discover that those shiny new boots come with free blisters.
Spare high calorie food, first aid equipment, torch, whistle and survival bag and you should know what to do with it.
If you’re on a diet for your weight then forget it on the mountain, you’ll burn off so many calories during the walk that you’ll generally not need to worry. You should be more concerned about getting enough calories as you can burn an extra few thousand calories walking up and down Snowdon.
You’ll need to take around 2 litres of water to be safe, maybe more if it’s exceptionally hot. Water or diluted fruit juice are good to keep your thirst quenched and contain natural fruit sugars, unlike many fizzy drinks. In cooler weather, a flask is always welcome at lunch stops.
In an emergency, stream water is usually drinkable if it’s fast-running over stony beds.
Of course you’ll be needing your map and compass, and know how to use them! Brush up on your navigation here.
Additionally you’ll need a rucksack large enough to hold all this gear in.
