Spoken by someone from a land which thinks "Midsummer" is in June!
No, It's Spring all the way down to the Equator. Spring is an Equinox, so it's predicated on the duration of sunlight ((lux/light) Equal nox (night)). The official beginning of Spring is, if I am correct, the moment when the Sun crosses the equator.
That shouldn't be mistaken for Sun-at-Azimuth (only possible in the tropics) or Sun-at-maximum North/South (extra-tropical).
The Old Country for me is located at 9° North Latitude. Because of that, there are 2 days each year when the Noon Sun is straight overhead. and neither of them are at equinox or solstice. Still, they don't have double seasons as weather
patterns aren't that simple.
On the actual Tropic latitude circles, the "real"
midsummer beginning of Summer - sorry! is at the Summer Solstice, so about June 21 and on that date the sun peaks directly overhead at the azimuth.
Here at 30° N, it gets close, but fails by about 7°. Up in England's Green and Pleasant, they don't even get close. Just bright bedtimes.
Of course, being the equinox, various henges, barrows and other constructs have all lit up for the occasion.
