Have you ever paused while writing and wondered whether you should say “in summers” or “on summers”? You’re not alone. This is one of the most common English grammar questions among students, writers, and English learners.
The short answer is simple: “in summers” is correct in most situations, while “on summers” is generally incorrect. Understanding why can help you sound more natural and confident in both spoken and written English.
In this guide, we’ll explore the difference between in summers or on summers, explain the grammar rules behind seasonal prepositions, provide examples, and answer frequently asked questions.
Understanding the Difference Between “In Summers” and “On Summers”
The confusion often comes from the way English uses prepositions with time expressions. Different prepositions are used for days, dates, months, years, and seasons.
The Correct Phrase: “In Summers”
When talking about a season, English speakers typically use the preposition “in.”
Examples:
- I enjoy swimming in summers.
- Many families travel in summers.
- The weather is usually hot in summers.
- Flowers bloom beautifully in summers.
These sentences sound natural because seasons are treated as longer periods of time, similar to months and years.
Is “On Summers” Ever Correct?
In standard English, “on summers” is usually incorrect when referring to the season.
Incorrect:
- We go hiking on summers.
- Schools close on summers.
Correct:
- We go hiking in summers.
- Schools close in summers.
The preposition “on” is normally reserved for specific days or dates.
Examples:
- On Monday
- On July 15
- On Christmas Day
- On my birthday
Because summer is a season rather than a specific day, “on” does not fit.
Why We Use “In” for Seasons
English follows a general pattern for time-related prepositions.
| Time Expression | Correct Preposition |
| Year | In |
| Month | In |
| Season | In |
| Day | On |
| Date | On |
| Time | At |
Examples
In + Seasons
- In spring
- In summer
- In autumn
- In winter
On + Days
- On Friday
- On New Year’s Day
- On Sunday morning
At + Specific Times
- At 5 p.m.
- At midnight
- At noon
Learning this pattern makes it easier to choose the right preposition in everyday English.
