London will host a huge number of Olympic and Paralympic events between July and September 2012.
The newly built Olympic Park will host the athletics, aquatics, hockey, basketball, handball, water polo and cycling, while existing venues at Greenwich Park, the Royal Artillery Barracks, Wimbledon, Lord's Cricket Ground, Horse Guards Parade and Hyde Park will play home to a range of events, from equestrian to shooting and beach volleyball to tennis.
The Met Office has many observation sites across London, some of which have been in place for more than 100 years. These include St James' Park, Kew Gardens and Heathrow.
Historical records show that the capital normally sees temperatures reach the low 20 °Cs by day. The prevailing wind is south-westerly and rainfall through July to September doesn't usually exceed 50 mm. On average there is around six hours of sunshine per day.
The circle below represents the direction the wind was blowing over July, August and September over a 10 year average from 2001-2011. The segments count the percentage of hours in the day where the wind was blowing from that direction.
