Read twelve months at a representative 81.47 m reserve point
Oxford Island’s 81.47 m sample has a comparatively narrow thermal cycle, from a 4.39 °C January mean to 14.62 °C in July. Rainfall averages 2.33 mm/day in the driest month, May, and 3.54 mm/day in the wettest, November; daylight varies from 7.11 hours in December to 16.89 in June. These are 1991–2020 NASA POWER normals for one Northern Ireland coordinate, not simultaneous readings from the lough shore, wetland, and woodland.
