When to plant Watermelon in Sant Katrin
South Sinai, Egypt
Watermelon is a warm-season trailing vine, grown flat along the ground for its big, sweet, thirst-quenching fruit — a cousin of pumpkin, cucumber and melon.
| Fit | Moderate |
|---|---|
| When to plant | 11 Apr 2027 – 9 Aug 2027 opens in 27 weeks |
| Expected harvest | about 18.4 t/ha |
| Harvest | From 30 Jun 2027 to 27 Nov 2027, depending on the planting date |
| Ready to harvest | 80–110 days after planting |
| Work it takes | 46–96 days per hectare, by hand |
Rain-fed. These dates are worked out from each place's own rainfall, for a field watered by the season — with irrigation a window can open earlier, close later, or come round more than once a year. Check your own field under What grows, or get the Divisi app for a calendar dated to your farm.
If you only get one chance to plant, aim for around 11 Apr 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Sant Katrin is close to normal, so these dates match the pattern the area usually follows.
Planting after 9 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Sant Katrin
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 30% |
For watermelon in Sant Katrin, the lie of the land is the tightest of the three at 30%. You cannot flatten it, but you can farm it: plant along the contour rather than up and down, ridge or tie ridges to hold water on the slope, and expect shallower rooting than the crop would manage on flat ground.

What it takes to grow watermelon in Sant Katrin
| Planting material | About 4,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 40 kg per hectare |
| Phosphate (P₂O₅) | About 11 kg per hectare |
| Potash (K₂O) | About 59 kg per hectare |

These are the nutrients a watermelon crop of that size carries off the field. What you actually apply depends on what your soil already holds — which is what a soil test, or the app's field records, tell you.
