Warm days without routinely fierce heat

September is among Lanzarote’s warmest months, but the usual daytime warmth is fairly moderate. Light clothing makes sense during the day, with a light layer as a backup for evenings rather than a heavy jacket. Nights remain warm on average, so comfortable sleeping conditions may matter when choosing accommodation. Humidity averages 76%, which can make the warmth feel a little sticky; the temperature alone does not tell the whole comfort story. Plan shade breaks around midday if you are sensitive to heat. This month suits travellers who want time outdoors in summer clothes more than those seeking reliably scorching afternoons.

Good swimming conditions, with little rain to plan around

The sea is warm enough for swimming by the usual comfort benchmark, making September a sensible choice if getting in the water matters to your holiday. Its year-to-year range is 22°C to 24°C, so personal tolerance still plays a part: comfortable swimming does not necessarily mean bath-like warmth. There is about 7.7 hours of sunshine within 12.2 hours of daylight, leaving plenty of scope for outdoor plans without promising clear skies throughout the day. Rain is unlikely to dictate your itinerary, though dry averages are not a guarantee. Pack sun protection and keep some flexibility rather than treating every afternoon as certain sunshine.
