When to plant Watermelon in Brida
Laghouat, Algeria
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.

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 21 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Brida is close to normal, so these dates match the pattern the area usually follows.
Planting after 20 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
