Daily temperature lag (climate, record, city, season)

[Derek41]

Seems to be more of a feature of mid latitudes, and proximity to the coast.
Perth for instance often reaches daily maximum after 3pm, and this is without daylight saving, whereas Geraldton is usually by lunch time.
Where I work, further up the valley inland, maximums often peak after 3pm, sea breeze only just penetrates to where I live before this.

It also depends on the time of year. In summer we get peaks around 5 pm, but in the winter it's more like 2 pm. (I'm just guessing at these times.)

Our peak temperature in the summer tends to come around 5pm-5:30pm.

Yes it is usually summer here too that daily highs can peak in late afternoon.
Winter is usually cooling at 3pm.

Yeah in London in summer it is usually about 4pm when we hit our high temperature.

Think of it this way, as someone already said, the minimum temperature is usually reached after sunrise, not before, because the sun is still at a low angle after sunrise and therefore cooling > heating effect from the sun.

Once the sun starts to rise, the heating effect of the sun takes over the effect of cooling. When the sun reaches its highest point in the sky, this is when heating is at its maximum, and heating>cooling by a long way. After solar noon, the heating effect of the sun is still higher than the cooling of the earth because the sun angle is still pretty high normally, until the point where cooling=heating which is around 4pm at mid latitudes.

I think in summer, since May here peak temperature tends to come around 4-5pm.

The same seems to happen here with the hottest part of the day being around 4-5PM.

Not as much lag here, it happens shortly after 2pm I think.

[flamingGalah!]

In summer the temperature peaks around 3pm-4pm here, though often it peaks earlier in the day at the airport...

Sometimes even, those cold overcast winter days tend to reached the highest temp at 4pm, an hour before sunset. In general, the warmest part of the day in the winter is around 2pm.
