It isn't the north you're looking for

We did Utah and the Grand Canyon in summer. Once. We won't do it again.

Not because it was bad — it was magnificent. Because you walk from six until eleven in the morning, and then you hide. A hiking day becomes half a day, and the rest is spent waiting for it to pass. We paid for a month of travel and used half of it.

Since then, temperature decides our destinations. And once you put it that way, you notice that the usual rule — "head north" — is a bad rule.

Why "head north" doesn't work

It excludes the best answers and lets bad ones in.

Ladakh in August sits at fifteen to twenty degrees by day under an almost permanently clear sky. It is at thirty-four degrees north — further south than Seville. Namibia in July is mild and dry, and it's in the southern hemisphere.

Conversely, there are heavy summers at high latitudes, and the interior of North America can climb a long way.

Latitude is a clue. It isn't the criterion.

The real parameter: your ceiling

Ask yourself one question: above what maximum temperature does your day stop working?

For us it's around twenty-four degrees. Above that, we don't walk in the afternoon.

That figure has a direct and underestimated consequence, and it isn't about comfort — it's about usable time. In a summer desert we walked from six until eleven, and then we stopped: the hiking day had halved. Under a Nordic sky, by contrast, it stays light so late you can set off again after dinner.

A three-week trip into a summer desert therefore contains less usable time than two weeks in Norway. That's what makes the question serious: heat doesn't make a trip less pleasant, it makes it shorter.

The four families

1. High northern latitudes — the obvious answer, and it's a good one

Norway, Iceland, Scotland, the Baltics, the Faroes, Lapland, the Gaspé, Alaska.

Twelve to twenty-two degrees by day. This is where most people escaping the heat go, and they're right: short flights, excellent infrastructure, endless daylight. The walking is serious — Norway and Scotland for the elevation, and in the Baltics there are over twelve hundred kilometres of waymarked coastal trail that nobody talks about.

A detail that surprises people: you swim. The Baltic sits at around twenty degrees on the Latvian coast in August, and the beaches are full.

The trade-off to know about: the temperature is reliable, the weather isn't. This is the one family where rain decides your days.

2. Tropical altitude — the least mentioned

Ladakh, Kyrgyzstan, the Pamirs, the Peruvian and Ecuadorian Andes.

Fifteen to twenty-five degrees by day, and July and August are the dry season. It is the family least talked about, and probably the one most travellers overlook while it answers exactly what they are asking for.

Kyrgyzstan deserves naming separately for a nature-led profile: altitude, lakes, yurts, horses, almost nobody, and not a single museum. Nobody will offer it to you.

The trade-off: a long flight, altitude to manage with children, and less established logistics.

3. Austral winter — dry and predictable

Namibia, the Drakensberg, Australia's Top End, Réunion.

Eighteen to twenty-six degrees, very little rain. Our Australia trip and our Réunion trip both fell in this window, without our having named it at the time.

The trade-off: a long flight, and a seasonal inversion that disorients at first.

4. European altitude — without a plane

The Alps hut to hut, the Dolomites, the Pyrenees, and northern Spain: Asturias, the Picos de Europa, Cantabria, Galicia.

Fifteen to twenty-four degrees. Reachable by car or train. Much cheaper than Norway or Iceland, which are among the most expensive destinations in the world.

This is the most underestimated family, for a simple reason: it lacks the exoticism of the north. But August in the Picos de Europa is cool, green, and the walking there is real.

The trade-off: afternoon storms in the mountains, and hut capacity that books out months ahead.

The north, honestly: rain days versus rain hours

Here is the correction that changes the most, and I had it wrong before.

You read that a coast sees close to one rainy day in two, and you give up. But a day with a forty-minute shower counts as a "rainy day" — and it spoils nothing.

The right indicator isn't the number of days, it's the number of rain hours during your active day. And where those hours fall matters as much as how many there are: three hours of rain between six and nine in the evening block nothing; the same three between nine and midday kill the day.

Our two stays in Iceland and Norway had very little actual rain, while the rain-day statistics promised far worse. Scandinavian rain is frequent and brief.

Scotland is the counter-example, and it needs saying: there, rain genuinely cancelled walks we had planned. It isn't the same rain.

And one factor people forget entirely: wind. On a ridge you turn back at sixty kilometres an hour of gusts under a clear sky, and you set off in drizzle when it's calm. For a ridge day, wind is the real blocker.

What climate change changes — and what it doesn't

Counter-intuitively: for summer rain, almost nothing.

The precipitation signal is mostly a winter one. Scottish summers are even projected to become warmer and drier, and some Norwegian regions are expected to see summer rainfall decline. A summer memory from fifteen or twenty years ago remains broadly representative for rain.

What genuinely changes sits in three other places:

Zones that have become too hot are spreading. That's what took Utah out of our summers.

Mountain roads close more often. Thawing permafrost and intense rainfall increase rockfall.

The reference averages have shifted. Standard climate normals cover 1991-2020 and already understate the present. Better to look at the last fifteen years.

Three questions, in this order

1. What is your ceiling? A temperature, not a region. If you don't know it, think back to the last summer when you stopped going out in the afternoon.

2. Is your date window negotiable? If it is, the same destination in June or September changes profile entirely, and that's the cheapest lever you have. If it isn't — school holidays, the commonest case — then the destination is your only variable, and that's what the four families are for.

3. What do you want to do there? A cool beach, a big daily walk, villages, canoeing. The answer eliminates two of the four families immediately.

This isn't a list to pick from. It's a filter, to apply in that order.

What we don't know

We have travelled in three of these four families, not the fourth — tropical altitude, which we write about here on the basis of climate data rather than our own legs. Readers should weigh that: we are describing a family we have not tested.

Our ceiling of twenty-four degrees is a parameter of the engine, set per traveller, not a rule: yours may sit elsewhere, and the engine takes it into account.

And the figures here are orders of magnitude. A valley and a neighbouring pass do not share a climate, and the week matters as much as the month. Check at the specific location before booking anything.

Framework drawn from our own trips between 2017 and 2026 and from work on selecting destinations by date window.
