Weather Forecast for Machakos, Kenya
Machakos is where the weather's dry side is the main character — Gatunga, Kiambo and the dry-season belt where two rainy seasons arrive (when they do) and the long dry spells between them decide the season. The dashboard here is most useful exactly where the wetter counties don't need it: tracking the dry spells as they build, and marking the rain events that carry a dry-season crop through.
Use the location bar below to search your exact farm — the dashboard loads for the point you pick, and the panels update to it. Current Weather is now; the Rainfall Forecast is the next 24 hours and the week; the Irrigation Weather Outlook is the LOW / MODERATE / HIGH attention call; and the Farm Activity Outlook covers field work, spraying, planting, transplanting, harvesting and irrigation. Select your crop in What Are You Growing? to read the same weather through its lens — the forecast never changes, only the interpretation.

Weather and farming in Machakos
Machakos sits on the dry side of the highlands at around 1,500–1,700 m, and its farming weather has the asymmetry that defines dryland Kenya: two rainy seasons that are genuinely variable, and dry spells that are not. The county's dry-season crops — the vegetables that grow in the gap between rains — exist because of that gap, and their water comes from the system, not the sky. The dashboard's two most-used panels here are the dry-spell alert (the early signal that a stretch is building) and the 7-day rain outlook (the map of which days the sky will help).
Two more local notes. When rain does come, it comes hard — the wet months' bursts are intense on dry, often bare ground, which is where runoff and compaction do their work; the rainfall chart's per-hour bars show the burst structure that the daily total hides. And the temperature run is high through the dry months, which the ET panel captures: a warm, windy dry day is pulling water out of the soil faster than the cooler counties' equivalent, so the same 0 mm of rain is a bigger deal here than on the Rift floor.
Served areas from this point: Gatunga, Kiambo and the Machakos town zone (including the eastern fringes toward Mwea). Search your specific area — in a county this broad, the town reading is a starting point, not the farm's number.
Crops this outlook reads for
From the What Are You Growing? selector on this page, the crops most worked here read the same weather with their own framings: Mango, Cabbage, Onions. The full list — sixteen crops — is available in the selector, and the crop pages carry the deeper agronomy.
FAQ
Weather questions from Machakos farms
The dry spell here is long — how should I read the dry-spell alert over weeks?
As a season indicator rather than a daily instruction. When it fires for four or more consecutive low-rain days, the honest read in Machakos is that the stored-water question is live. The outlook stays LOW while the model sees no rain coming, and that is correct — there is no weather asking for a change — but the design implication (storage, scheduling, source capacity) is exactly the thing a farm assessment works out with your numbers. The alert makes the dry spell visible; the design answers it.
Does a LOW irrigation outlook in the dry season mean the crop is fine?
No — and that is the point of the level's name. LOW attention means the weather is not asking for a change in your plan; it is not a statement that the crop is watered. In a dry Machakos month the crop's water is coming from your system, and the LOW level is the confirmation that the weather isn't going to interfere with your schedule. The check that keeps you honest is the soil, as always.
Why does the ET (water loss) reading run higher here than on the Rift?
Because it is a weather-only number and the weather here is hotter and often windier in the dry months. Higher temperature, more sun, more wind — each pulls more water from an open surface, and the ET figure is their combined effect. It does not measure your crop's need, but it does explain why a 0 mm day costs more soil moisture here than the same 0 mm day in a cooler county.
The forecast shows rain in the dry season — how much should I bank on it?
As much as any dryland forecast deserves: the shape, not the script. A system of rain visible in the 7-day window is worth preparing for (clear the intakes, plan around it), and worth using for the crop if it lands — but the dry-season farm is built on the assumption that the rain is a bonus, not the budget. The stored water and the system are the budget; the forecast tells you when the bonus is coming.
How should a dry-season vegetable crop use the 24-hour rainfall chart?
As the scheduling input: the chart shows which hours the model expects the rain in, so a fertigation or irrigation run can be placed ahead of the burst to ride it into the profile, and the field work can be placed in the dry gaps. In a county where the rain is the scarce event, the hour-level view is the difference between catching it well and missing it.
