A weather system bringing hot and dry air has prompted fire alerts in Tenerife. The Canarian Government’s Emergency Management has declared a wildfire risk alert, effective from Sunday, 5 July 2026. The warning particularly concerns the south and west-facing mountain areas of the island, which will face high temperatures and extremely dry conditions in the coming days.
Forecasts indicate temperatures in Tenerife will rise to between 32°C and 35°C, notably affecting the southern and western municipalities. Experts warn that thermal inversions will initially occur between 500 and 700 metres but will gradually lower during the week, creating a dangerous “cap” effect that traps warm air over the island’s forests, dropping humidity levels below 30%.
Wind conditions are also a major concern, with moderate easterly (trade) winds expected to strengthen at times, particularly in exposed regions and between the islands. Additionally, a slight dust intrusion will cloud the skies. While officials do not anticipate alarmingly high dust concentrations, the overall risk will be continuously monitored, and restrictions may be tightened if conditions worsen.
Gran Canaria is also on alert for wildfire risks above 400 metres. The heatwave is set to affect the island starting Sunday, with peak temperatures expected between 34°C and 36°C, potentially hitting 38°C in certain inland areas by Monday. The combination of low humidity and moderate winds has led to the activation of all prevention and fire suppression protocols in response to the summer’s first significant heatwave.
