The best time to go to Tarves is during the summer months, from June to August, when the weather is generally mild and the days are long.
During this period, you'll experience the most pleasant temperatures, typically ranging from 15°C to 20°C, making it ideal for exploring the Aberdeenshire countryside and visiting local attractions. The extended daylight hours, sometimes lasting until late in the evening, provide ample opportunity for sightseeing and outdoor activities. This is also when most local events and Highland Games take place in the wider region, offering a taste of Scottish culture.
For those looking to avoid the peak tourist season but still enjoy relatively good weather, late spring (May) and early autumn (September) are also excellent choices. May often brings blooming wildflowers and fewer crowds, with temperatures averaging around 12-15°C. September offers crisp air and beautiful autumn colours, with similar temperatures to May, making it superb for walks around places like Haddo House Estate without the summer rush.
Ultimately, if you're seeking the warmest weather and longest days for an extensive and relaxed visit, summer is your best bet.
