Summer brings long-awaited dryness and clarity. July and August are the driest months of the year, when the number of rainy days drops to 5–6 per month. During this time, the chance of rain is minimal, making summer the best time for city walks and outdoor activities without fear of getting wet.

Since the weather in Renton can be changeable, layering your clothing will be your best strategy. For a trip between late autumn and early spring, when the number of rainy days is high (up to 21 days in January), be sure to pack a high-quality waterproof jacket or raincoat. Insulated and water-resistant footwear is also essential to stay comfortable while exploring the city on cool, damp days.

Summers here are usually mild and pleasant, with temperatures around 20–25°C, so light clothing made of natural fabrics is perfect for July and August. However, even during the warm season, evenings can be chilly, so having a hoodie, fleece, or light sweater in your suitcase is highly recommended. Don't forget sunglasses and sunscreen, as precipitation decreases significantly in mid-summer and sunny days become more frequent.

Regardless of the season, the most important part of your wardrobe should be comfortable walking shoes, as you'll be doing a lot of exploring on foot. A compact umbrella won't take up much space in your luggage, but many travelers find a jacket with a deep hood more practical for protecting against the wind and the characteristic local drizzle. In winter, a scarf and gloves won't go amiss, as temperatures regularly hover around 3–5°C.
