The best time to go to Purfleet is generally during the late spring and summer months, from May to September, when the weather is mildest and the days are longer.This period typically offers temperatures ranging from 15°C to 22°C (60°F to 72°F), making it pleasant for exploring the outdoors. You'll find the RSPB Rainham Marshes, a key attraction, at its most active with birdlife during these months, and the paths are drier and more comfortable for walking.For those interested in outdoor activities and nature, particularly birdwatching, these months are ideal. The longer daylight hours mean more time to enjoy the marshland landscapes and observe the diverse wildlife in comfort.
