Why isn’t the equator hotter in spring and autumn?

In June the northern hemisphere is tiled towards the sun and in December the Southern Hemisphere is most tilted towards the sun so in spring/autumn wouldn’t the equator be most towards the sun so it would be hotter?

The change is small. The intensity of the suns rays on the equator at the solstices relative to the equinox is cos(23.43 degrees) or 91.7%.

By contrast the swing is Minneapolis goes from cos(45-23.43) to cos(45+23.43) which calculates to a swing from 36.8% to 93.0% which is very large… a factor of over two and half.

Meteorologists will point out that the 8.3% swing at the equator can probably be seen in the weather patterns somehow… when the rains come, etc, but it’s pretty small compared to more temperature areas.
