Welcome to WeatherAction

WeatherAction long-range forecasts are produced using Piers Corbyn's Solar Weather Technique.

The technique uses predictable aspects of solar activity -particle and magnetic effects from the Sun - as the basis for forecasting weather many months ... and even years ... in advance.

Weatheraction forecasts are the only long-range forecasts with proven skill verified by independent academic statisticians with their findings published in scientific peer-reviewed literature (see Forecast Accuracy).



The forecasts for each month for Britain & Ireland - which are based on WeatherAction long range Europe & North Atlantic forecast maps - are constructed in time windows of just a few days, and include

• Detailed worded weather descriptions with maps and graphics
• The Most likely weather scenarios in each time spell.
• Warnings of weather extremes, e.g. when the wettest, windiest, warmest and coldest spells will occur.
• 'Solar Factor' most likely corrections which need to be applied a few days ahead to standard Meteorology forecasts as issued on TV
  

For samples of the forecasts please see Forecast Archive.

The unique power of Solar Weather Technique forecasts have been proven by significant profits made on Scientific Weather Bets with William Hill at odds and verification organized independently by the UK Met Office (More information under Forecast Accuracy).

The latest Britain & Ireland 30 day ahead forecast can be purchased on-line via the 'Buy Forecasts' tab.  30 day forecasts for each month are issued near the end of each preceeding month and are available from then until the next forecast is available for on-line purchase. Longer Range forecasts up to 12 months ahead are also available.

WeatherAction also forecasts for certain extreme events around the world which are made public for each month at the WeatherAction Press conference towards the end of each preceding month. The Audited results of these forecasts show high skill - 85% success rate for the world and over 90% for USA on land - see reports under  Forecast  Accuracy button and the 30 day monthly bulletins via Forecast Archive include the month ahead world extreme event forecasts and reports. The May Forecats bulletin page 4 gives overall results estimates (also in WA Press News 2009 No 28) which under the final audit reports turn out as 85% level (63/74) for the world and over 90% (8.5/9) for N America land events.

Longer ahead extreme event forecasts for various parts of the world including Atlantic Tropical Storms and West North Pacific typhoons and East North Pacific Typhoons - all to  the end of 2009 seasons - are being made available by direct subscription - please Email back for further information.
