Grouse Mountain mild as the Lower Mainland. In December (the coldest month statistically), Grouse Mountain has an average high and low of and respectively. This freeze/thaw cycle can allow for large amounts of rain to fall on some occasions every winter. Nonetheless, heavy snow is more frequent in the winter, which allows for a deep snow-pack, lasting on average from mid-November until early May. Summer is warm and relatively dry. August is the warmest month, with an average high and low of and respectively. Grouse Mountain has built an observation deck (accessible by elevator) on a 1.5 megawatt wind turbine of Leitwind
Driven grouse shooting correlated with higher densities of red grouse, golden plover, curlew, lapwing, redshank and ring ouzel. Research has also shown that on moors managed for grouse shooting, ground nesting birds such as curlew and lapwing, both of which are species of the highest conservation concern in the UK, are 3.5 times more likely to raise a chick to fledgling stage. Studies on a former grouse moor in Berwyn found that within 20 years of grouse moor management ending, lapwing became extinct at the site, golden plover declined by 90 per cent, and curlew declined by 79 per cent. However, research also
