Wellington

General Climate Overview

Wellington has a temperate maritime climate (classified as Cfb under the Köppen climate classification). This means the city experiences mild temperatures year-round, with no extreme heat or cold. However, it is famously windy, earning it the nickname "Windy Wellington." The strong winds are due to the city's position between the Tasman Sea and the Pacific Ocean, where the Cook Strait acts as a natural wind funnel.

• Average Annual Temperature: Around 12–15°C (54–59°F).
• Average Annual Rainfall: Approximately 1,200 mm (47 inches), spread relatively evenly throughout the year.
• Sunshine Hours: Wellington enjoys about 2,000 hours of sunshine annually, which is moderate compared to other New Zealand cities.

Key Weather Considerations for Daily Life and Travel

1. Wind: The wind is a defining feature of Wellington's climate. It can make temperatures feel cooler than they are, so dressing in layers and carrying a windproof jacket is advisable year-round. The wind can also occasionally disrupt ferry services across the Cook Strait or flights into Wellington Airport, so travelers should check schedules during particularly windy days.

2. Rain: While Wellington does not have a distinct rainy season, showers can occur at any time of year. A compact umbrella or waterproof jacket is a must-have for both residents and visitors.

3. Sun Protection: Despite its moderate temperatures, New Zealand has high UV levels due to its location under the ozone hole. Sunscreen, sunglasses, and a hat are essential, especially during summer.

4. Microclimates: Wellington's hilly terrain creates microclimates, meaning weather conditions can vary significantly across the city. For example, the central business district (CBD) may be sunny, while the surrounding hills experience rain or fog.

5. Seasonal Events: Wellington hosts numerous events and festivals throughout the year, such as the New Zealand Festival of the Arts (summer) and Wellington on a Plate (winter). Weather conditions can influence outdoor events, so it's wise to check forecasts and plan accordingly.

• Commuting: The wind can make cycling challenging, but Wellington has a reliable public transport system (buses, trains, and ferries) that operates in most weather conditions.
• Clothing: Layering is key in Wellington, as temperatures can change quickly throughout the day. A windproof and waterproof jacket is a staple for both residents and visitors.
