The best time to go to Seathwaite really depends on what you're hoping to experience, but generally, the late spring and summer months from May to September offer the most favourable conditions.For walkers and hikers, July and August are often ideal. The weather is typically at its warmest and the days are longest, giving you plenty of daylight hours to explore the fells and valleys. This is also when the paths are usually driest, making for easier and more comfortable walking, especially on routes like the ascent to Scafell Pike or the walks through Borrowdale.However, if you prefer to avoid the busiest periods and still enjoy good weather, May, June, and September are excellent choices. These months often have pleasant temperatures and fewer crowds, allowing for a more tranquil experience on the trails.
