In summer (June to August), daytime temperatures are quite comfortable, around +17-19°C, so T-shirts and light trousers will come in handy. However, evenings and mornings can be chilly, so don't forget a sweater or fleece. In winter (December to March), Interlaken is frosty, with temperatures often dropping below freezing. Prepare for the cold: you'll need a warm jacket, thermal underwear, a hat, gloves, and a scarf. In the shoulder seasons (spring and autumn), the weather is particularly unpredictable, so a combination of light and warm clothes is the best solution. Regardless of the season, don't forget sunscreen and sunglasses—the sun can be very intense in the mountains.
