Quito in September — Full Picture
September is a strong shoulder month — around 21°C/8°C (70°F/46°F), still largely dry and sunny (about 65mm) as the dry season begins to wind down. Mountain views remain good and the weather is reliable.
With the peak-season crowds thinning, it offers a sweet spot of decent weather, lower demand, and more moderate prices. Cotopaxi, the TelefériQo, and Otavalo are all still rewarding, and the city feels less hectic than mid-summer.
The usual high-altitude rhythm holds: warm, sunny days and cool nights, so layer accordingly. A few more showers start to creep back later in the month, so a light rain jacket is worth having.
Note: it's still a popular time, but easier on the wallet and the queues than July-August. The altitude sun stays intense — daily sunscreen, a hat, and sunglasses. A well-balanced month for first-time visitors.
What to Wear & What to Pack
Dry season easing — around 21°C/8°C (70°F/46°F). Layers for warm days and cool nights, with a rain jacket as the odd shower returns. Strong sun protection for the equatorial UV.
