AEMET: storms, hail and wind gusts on Tenerife up to 30°C
Temperatures on Tenerife and the archipelago reach 30°C with calima. AEMET predicts unstable weather with storms, hail and strong wind gusts.

Temperatures on the Canary Islands remain significantly above the norm for the end of September. On the south of Tenerife, thermometers may indicate 30°C. On the south of Gran Canaria, they may exceed 36°C. The intensification of heat is starting to weaken. Initial changes will be slight.
The weather becomes unstable. The sky will be cloudy. Saharan dust (calima) remains suspended in the atmosphere. Storms are expected to develop around Tenerife and the western islands. These may bring sudden, heavy rain and hail. This is instead of prolonged drizzle. Winds will generally be weak, blowing from the north-east. Storms may generate sudden, stronger gusts. This is especially on exposed, southern mountainous areas.
At sea, conditions are rough. Waves reach about 1.5 metres on northern coasts. They exceed one metre on southern coasts. Prepare for sudden wind gusts and storms with hail. Check flight status. Avoid beaches during storms.
