Conditions at Habitat 67 in May
May: Green Banks and a Flat River
By May, average air temperature climbs to 13.1°C and Montreal begins to shake off winter, but the St. Lawrence River shows no wave pulse. Average swell height is 0.0m, average period is 0.0s, and the ideal wind rating is 0%. Wind directions are dominated by WSW (13.0%), SW (8.1%), NE (8.4%), and SSE (7.4%), with most speeds in the light 0-20kph range. The offshore quadrant totals about 20.5%, but without a fetch or open-ocean storm track, those winds just produce streaks on a mostly flat surface. Precipitation averages 2.84 mm/day, but thermal heating starts to generate afternoon breezes; unfortunately they blow from the onshore SSW/SW quadrant, further discouraging any hope of clean waves.
