Best Time to Visit Farnham
Farnham has a typical southern English climate: mild but changeable. The town is busiest during the summer market and the autumn farmers' market, but spring and early autumn offer the best balance of decent weather and fewer visitors.
✦ Go in May or September for comfortable weather, fair prices, and a relaxed atmosphere.
✅ Best months
May and September. May has long, mild days and the gardens at nearby Frensham Great Pond are in bloom. September is often warm and dry, with the Farnham Food and Drink Festival drawing crowds without overwhelming the town.
🔥 Peak season
August. The historic Farnham Carnival and summer holidays push hotel prices up 20-30%. The town feels lively but not unbearable; booking a month ahead is wise.
💷 Shoulder (best value)
Late April and early October. April sees the Farnham Literary Festival, but crowds are light. October has crisp air, the autumn colours in Bourne Wood, and hotel rates drop 15% from summer highs.
🌙 Quietest & cheapest
January and February. Cold and wet, but rates can be 40% off peak. The trade-off: many pubs run reduced hours, and Farnham Castle tours are limited to weekends.

🧳 What to pack
