8 August 2012 - With so many outdoor sporting events at London 2012 it's essential to know what the weather has in store - and not just for organisers and athletes.
Jam-packed crowds at outdoor events have a been a key feature of the games - from the masses lining the shores at Weymouth, to packed grandstands at Eton Dorney or thronged streets in London.
An estimated 200,000 people turned out to watch Alistair and Jonny Brownlee storm to gold and bronze medals in the triathlon in London on Tuesday. On the same day, people checked up on the weather on the Met Office's mobile apps for iPhone and Android more than 1 million times.
Crowds can use the apps to find out what the weather has in store before they leave home or while on the move so they can be prepared and make sure they're ready to enjoy all the action.
With many more outdoor events still to come, including the men's marathon on the streets of London on Sunday and many more events in the Paralympics, there's still plenty more to outdoor competition to come.
Throughout the London 2012 Olympic and Paralympic Games everyone will be able to access Met Office forecasts for all the sporting venues, in addition to more than 5,000 sites it already provides forecasts for.
For those inspired by Team GB to get outside and involved in sport, the Met Office now also provides a range of leisure forecasts that give specific information for beaches, bays and estuaries, national parks, and outdoor recreation centres all over the UK.
So whether you're heading out to watch the action or planning on taking part in your own sporting endeavours, the Met Office can give you all the information you need to prepare and stay ahead of the weather.
