Three Weeks of Rain Cost Him More Than Diwali Made Him

Everyone plans for Diwali. Almost nobody plans for the monsoon, the exam season, or the summer shift — and those quietly move more stock.

Gopal plans meticulously for Diwali. He has done for years, and it works. What he had never planned for was the three-week stretch of heavy rain that arrives most years in his part of Kerala, during which his footfall halves and his fresh stock spoils.

Across a year, the monsoon moved more money in his shop than the festival did. He had simply never treated it as a season.

The Seasons Nobody Plans For

Festivals get attention because they are dated, visible and universally discussed. The other seasonal patterns are just as reliable and almost entirely unmanaged.

• Monsoon: footfall drops, basket size rises, fresh goods spoil faster, delivery demand jumps
• Summer: cold drinks, ice cream and cooling products surge; refrigeration load and failure risk rise with them
• Exam months: snacks, stationery and late-evening trade shift noticeably in residential areas
• School reopening: a short, sharp spike in specific categories
• Wedding season, which varies regionally but is highly predictable locally
• Month-end and salary week, which is a seasonal pattern on a monthly cycle

That last one is worth separating out. In most residential neighbourhoods, the first week after salaries is a different shop from the last week of the month — larger baskets, more packaged goods, less credit.

I planned for the four days of Diwali and ignored the twenty-one days of rain that cost me more.

What the Monsoon Actually Does

It is the most consequential and the least planned, so it is worth taking in detail.

Footfall falls, baskets grow

People shop less often and buy more each time. That means fewer, larger transactions — so running out of a staple hurts more than usual, because the customer is buying a week at once.

Fresh goods spoil faster

Humidity shortens shelf life for produce, bakery and anything not sealed. The same stock that lasted four days in March lasts two.

Deliveries become the business

Home delivery demand rises sharply, and the shops set up to handle it capture trade from the ones that are not.

Supply becomes unreliable

Your suppliers face the same roads you do. Lead times stretch, and a reorder point calculated on a four-day lead time is wrong when the lead time becomes seven.

A reorder point is average daily sales multiplied by lead time, plus safety stock. Both halves move seasonally — demand shifts and supplier lead times stretch. Reviewing them at the start of the monsoon and again at the start of summer prevents most seasonal stockouts, and takes about twenty minutes for your top twenty products.

Using Last Year Instead of Instinct

If you have item-level sales history, the plan is already written. Four numbers do most of the work.

• Units sold per item during the same window last year, not rupees
• The dates the shift began and ended, so you buy at the right time rather than early
• What ran out, and how many days before the peak of the period
• What was still on the shelf when the season ended

That fourth list is the one nobody keeps and everybody needs, because it is the direct answer to what not to buy again.

Practical Adjustments

• Reduce fresh and short-life ordering during high humidity; order smaller and more often
• Increase depth on staples and packaged goods, since baskets grow
• Check refrigeration seals and service before summer, not during it
• Extend supplier lead times in your reorder calculations for the rainy weeks
• Set up delivery properly before you need it, not in the middle of a downpour

Arali keeps item-level history, so the same window a year earlier is something you can read rather than remember. Whichever season is next where you are, twenty minutes with last year's figures for your top twenty products is the cheapest planning you will do.

Frequently asked questions

How should a shop plan for the monsoon season?

Reduce fresh and short-life ordering because humidity shortens shelf life, increase depth on staples since baskets grow while footfall falls, extend supplier lead times in your reorder calculations because deliveries slow, and set up home delivery before you need it. Monsoon moves more money in most shops than any single festival.

What seasonal patterns do small shops usually miss?

Everything that is not a festival: the monsoon, summer cooling demand, exam months, school reopening, wedding season, and the monthly salary-week cycle. In most residential neighbourhoods the week after salaries is effectively a different shop from the last week of the month — larger baskets, more packaged goods, less credit.

Do reorder points need to change by season?

Yes. A reorder point is average daily sales times supplier lead time plus safety stock, and both halves move seasonally — demand shifts and lead times stretch when roads are bad. Reviewing them for your top twenty products at the start of the monsoon and again before summer takes about twenty minutes and prevents most seasonal stockouts.

How do I use last year's data for seasonal planning?

Look at units sold per item during the same window last year rather than rupees, the dates the shift began and ended, what ran out and how far before the peak, and what was still unsold when the season ended. That last list is the direct answer to what not to buy again, and it is the one almost nobody records.
