What Extreme Heat Can Reveal About Your Home

Wales has experienced a prolonged period of hot, dry weather, and when temperatures climb for days at a time, we tend to notice things about our homes that barely cross our minds during the rest of the year.

In South Wales, we're understandably used to thinking about how our homes perform in colder, wetter weather. We look for good insulation, efficient heating, double glazing and protection from draughts.

But how a property performs in hot weather matters too.

A prolonged spell of sunshine can highlight everything from poor airflow and rooms that regularly overheat to the importance of garden orientation and natural shade.

And if you're thinking about buying a house, viewing properties during the summer can reveal some genuinely useful information about how that home might feel to live in.

1. Which Rooms Get the Hottest?

One of the first things you'll notice during a heatwave is that temperatures can vary significantly from one room to another.

The direction a property faces plays a big part.

South-facing rooms can receive direct sunlight for much of the day, while west-facing rooms are exposed to stronger afternoon and evening sunshine. That can be fantastic for natural light, but those rooms may also become considerably warmer during prolonged hot weather.

Upstairs bedrooms and loft conversions can be another area where heat becomes particularly noticeable, as the upper floors of a home often feel warmer.

If you're viewing a property during hot weather, don't just admire how bright it is. Take a moment to notice how comfortable each room actually feels.

2. Insulation Isn't Just About Keeping Your Home Warm

When we talk about home insulation, it's normally in the context of winter.

But insulation works both ways.

As well as helping to reduce heat loss when it's cold outside, effective insulation can help slow the transfer of heat into your home during warmer weather.

That means the insulation in your walls and loft can influence how quickly your home heats up on a hot summer's day.

If certain areas of your property become noticeably hotter than others, it may be worth considering whether insulation is playing a part.

3. Good Ventilation Can Make a Big Difference

Opening every window in the house might seem like the obvious solution when temperatures rise, but effective ventilation is more about creating airflow.

Homes with windows or openings on different sides of the property may allow air to move through more easily, creating cross-ventilation.

This can become particularly useful in the evening when outdoor temperatures begin to fall and you want to release the heat that has accumulated indoors throughout the day.

The layout of a property, the position of its windows and how easily air can move between rooms can all affect how comfortable it feels during warmer weather.

It's something few buyers think about during a typical property viewing, but a heatwave can make it very obvious.

4. Large Windows Have Pros and Cons

Natural light is understandably high on many buyers' wish lists.

Large windows, bi-fold doors and patio doors can transform a room, making it feel brighter, bigger and more connected to the garden.

However, large areas of glazing exposed to direct sunlight can also contribute to a room becoming considerably warmer.

This doesn't mean big windows are a bad thing. Far from it.

It simply highlights the importance of considering the property's orientation and whether there are suitable blinds, curtains, awnings or other forms of shading.

When you're buying a home, it's worth thinking beyond how much natural light a room receives and considering when it receives that sunlight too.

5. Garden Orientation Isn't the Whole Story

A south-facing garden is often one of the first features highlighted when a property comes onto the market.

And understandably so.

For buyers who love spending time outside, having plenty of sunshine throughout the day can be a huge attraction.

But a spell of extreme heat demonstrates why garden orientation isn't the only thing that matters.

Mature trees, pergolas, covered patios, planting and shaded seating areas can make an enormous difference to how usable a garden is during the hottest parts of the day.

An east-facing garden might be perfect for someone who enjoys their morning coffee outside, while a west-facing garden can be ideal for people who want to enjoy the evening sun after work.

Rather than automatically searching for a particular garden orientation, think about when and how you'll actually use the space.

6. Your Loft Can Have a Big Impact

Roof spaces can become extremely warm after prolonged exposure to sunshine.

Because of their position at the top of the property, lofts and converted attic rooms can be particularly susceptible to overheating during periods of high temperatures.

Appropriate insulation and ventilation can therefore be important considerations, particularly if you're buying a home with a loft conversion or bedrooms located within the roof space.

Again, this is something that may barely register during a viewing on a cold February afternoon but becomes much more obvious in the middle of summer.

What Should You Look for When Viewing a House in Hot Weather?

If you're house hunting in South Wales during a period of hot weather, use it to your advantage.

Pay attention to how the property actually feels rather than concentrating solely on how it looks.

Notice whether upstairs bedrooms are considerably warmer than downstairs rooms. Look at which direction the main living spaces and garden face. See whether windows can be opened to create good airflow and consider whether there are naturally shaded areas both inside and outside.

It's also worth asking yourself a simple question:

Would I be comfortable living here during weather like this?

No home is going to remain perfectly cool during extreme temperatures, but viewing during different weather conditions can give you another perspective on what living there might actually be like.
