A note about English...

As the previous four members have all used the word 'autumn' for the season following summer, it's probably worth pointing out that 'fall' is only used in American English. All the other seasons are the same, though!

In Dutch/Flemish:

summer : zomer
autumn : herfst
winter : winter
spring : lente

In Azerbaijani  

summer   --- yay

autumn -----payız

Winter-----qısh

spring ---- yaz  or bahar

Here in Brazil:

Summer: verão
Autumn: outono
Winter: inverno
Spring: primavera

Spring: Bahaar

Summer: Taabestan

Autumn(Fall): Paayiz

Winter: Zemestaan

Good discussion :)
