The best time to visit Boulmer for good weather and outdoor activities is typically from late spring to early autumn, specifically May through to September.During these months, you'll find the most pleasant temperatures, longer daylight hours, and generally less rainfall, making it ideal for exploring the Northumberland coastline, walking the Boulmer to Alnmouth path, or simply enjoying the beach. The sea temperatures are also at their warmest during late summer, which is better for swimming or watersports.For those who prefer a quieter experience and don't mind cooler weather, April and October can also be lovely. You'll still have good opportunities for walks and sightseeing, often with fewer crowds, and the changing colours of the landscape can be quite striking.
