When to Plant? How Uganda’s Changing Rainfall Is Shifting the Calendar
You prepared your land in February. You planted on time, the way you always have. Then the rains disappeared for three weeks. Your seedlings are struggling, and you are checking the sky every morning wondering if you made a mistake.
You did not make a mistake. The calendar changed under you.
The Rains Don’t Follow the Old Calendar Anymore
For generations, Ugandan farmers planted by memory: first rains in March, second rains in September, like clockwork. That clockwork is broken. Forecasters at the IGAD Climate Prediction and Applications Centre (ICPAC), which tracks weather across the Greater Horn of Africa, have flagged repeated seasons in the past two years where large parts of Uganda received below-normal rainfall during what should have been the main growing season, while other areas saw the opposite problem: heavier rain than usual arriving late.
That is the real danger: it is not simply “less rain” or “more rain.” It is rain that no longer respects the window you planted your seed for. A dry spell that hits three weeks after germination can do more damage than a dry season that never started, because by then you have already spent money on seed, land preparation, and labour.
For a smallholder working one to three acres, this is not an inconvenience. It is the difference between feeding your household this year and borrowing to survive until the next harvest.
What You Can Actually Do About It
1. Check the forecast before you touch your hoe. ICPAC publishes free seasonal outlooks ahead of each of Uganda’s two growing seasons, plus monthly and weekly updates during the season itself, all posted on icpac.net. You can also sign up to get the monthly forecast by email. Before you commit land, labour, and seed money to a planting date, spend ten minutes checking whether the coming season is expected to be wetter, drier, or near normal in your region. This alone can save you a wasted planting.
2. Match your crop to the window you actually have, not the one you wish you had. If forecasts point to a shortened or unreliable season, this is not the year to bet everything on a long-maturing maize variety. Consider:
- Fast-maturing bean varieties bred for short, unpredictable rains, some mature in around two months instead of three.
- Sorghum, which tolerates dry spells far better than maize and still gives you grain to sell or eat.
- Drought-tolerant maize hybrids bred specifically for East African conditions, varieties like NAROMaize-57, TEGO (marketed as WE2115/WE2114), Longe 10H, and Bazooka are bred to keep producing through moisture stress that would wipe out an ordinary hybrid.
3. Don’t plant everything on one day. Stagger it. Planting your whole plot on a single date is a bet that the rain will behave exactly as expected. Spread that bet instead: plant roughly 60% of your acreage at the recommended date, then hold back the remaining 40% and plant it a week to ten days later. If the early rains fail or the seedlings are damaged, you have not lost the whole season — you still have a second planting coming.
4. Catch the water while it’s there. Even an erratic season usually brings intense rain in short bursts rather than a steady drizzle. Simple, low-cost water harvesting, digging shallow trenches (fanya juu) along the contour of a sloped field, or building small earth bunds around planting basins, traps that water in the soil instead of letting it run off. This buys your crop extra days of moisture between rains, which is often exactly the gap that separates a surviving crop from a failed one.
5. Know where to get certified drought-tolerant seed. These varieties are only useful if you can actually buy them. NARO develops them through its Namulonge and Serere research institutes and distributes early-generation seed to contracted seed companies, who multiply and sell it through registered agro-dealers. Ask your nearest NAADS-accredited agro-dealer specifically for drought-tolerant varieties by name. Supply has run short in past seasons, so don’t wait until planting week to look.
The Uganda Context
Uganda’s farming calendar is built around a bimodal rainfall system: a first season roughly March to May, and a second roughly September to November. That basic structure hasn’t disappeared. What has changed is the reliability of the rain within those windows: onset dates shifting later, dry spells appearing mid-season, and the swing between “wetter than normal” and “drier than normal” happening from one season to the next with far less warning than farmers are used to. This is exactly why checking each season’s forecast individually now matters more than trusting the calendar your parents used. The old dates are still a reasonable starting point. They are no longer a guarantee.
What To Do Today
Before you plant this season, do three things: check ICPAC’s current forecast for your region, ask your agro-dealer whether they stock a drought-tolerant variety suited to your area, and decide now, before land prep, not during it, how you’ll split your planting into two rounds instead of one.
None of this costs much. All of it buys you a second chance if the first rains don’t behave.
