For the average car... NO
It is best to follow the OEM recommendations.
If you have a performance enhanced engine... and/or actually work the engine harder then average people... YES, choosing different oils for different driving conditions is wise.
For extreme heat... nothing beats synthetic 10w30syn
For extreme cold... nothing beats synthetic 0w30syn
For average summers with moderate-heavy use... 10w30 or 10w40
For average winters with moderate-heavy use... 5w30

Its been common practice to use 10w-30 in the summer, 5w-30 in the winter.... why? 10w-30 contains less volume index improvers and pour point depressants.... so it shears less, under higher heat...
5w-30 contains a lot more..... and may end up after a couple thousand miles a 20 weight at operating temp...
But oils today are getting better and better..... 5w-30 will do excellent in all conditions!!

Most oils are multi grade susch as 10-30 W
The 10 is thinkness at freezing I believe
The 30 is thickness in hot weather.
No need to use different oil. Unless you in Arctic weather.

many car companys reccomend the 5W30 in the winter and the 10W30 in the warmer months. Bottom line is it all breaks down to 30W once warm. So with that said 10W30 is fine and wont hurt your engine at all summer or winter.

I live in Manitoba Canada....temperatures range from 100 deg in then summer to -45 deg. in the winter. All I use is 10W30 year round... in all my vehicles. 1986 Ford F150 with 225,000 miles on it, and 1988 Dodge Dakota with 250,000 miles...no problem with either one.
Both start just fine in the winter, and motors don't burn oil.

It depends on temperature variance.
If you live in North Dakota you need different oil than people in Florida durring winter.

yes, most car manuals give a temp range in the owners manual. in summer the oil is thicker (hot weather thins the oil more) and a thinner one in winter. just ask the guy at the quickie oil change place

todays multi viscosity oil will work fine year round. In colder climes I would use 5-30 weight, warm climes use 10-30 weight.
