WeatherAction forecasts, which have independently proven peer-reviewed significant skill - unlike all others in the field and proven skill in weather bets with William Hill (See forecast accuracy for references ) - are based on our revolutionary Solar-Lunar-Action-Technique (SLAT) which is increasing in scope and skill as our researches advance.

Useful presentations on SLAT and WeatherAction forecasts:

WeatherAction Long-Range forecasts are world leaders

They give possible likely weather scenarios (+/-1d) in typically 8 time periods per month for Britain+Ireland, Europe, USA regions. They are NOT substitutes for short range detail but provide a likely scenario for LongRange decisions and choicesand are normally more accurate and applicable than standard meteorology on all time scales from months ahead to 5days ahead. WeatherAction are the only LongRange forecasts with proven peer-review published significant skill.

In addition to LongRange detail typically within 1 or 2 days resolution WeatherAction Solar factors - R5, R4, R3... ( in all forecasts) give advice which point to improverments of short range model forecasts.

Comments and news in forecasts and here and in blogs linked below deal with both LongRange Forecasts and medium-short Weather and geophysical effects - eg aurora - of solar factors in Br+Ir, Europe, USA and across the world.

Follow @Piers_Corbyn on twitter for very latest news and comment. Note Piers' tweets/retweets of standard model output at times may not imply agreement but is more information since models change so much in this Wild-Jet-Stream / Mini-Ice-Age era.

ALL PAST FORECASTS are available in the web access boxes for current forecasts and in the Forecast archive (Via Forecasts tab) as it updates. Forecasts are normally for each MONTH and in (up to) 8 sub periods Br+Ir, Europe inc Scandanavia and USA. In forecast access & notes BI, B+I, BrIr, Br+Ir = Britain+Ireland; Eu = Europe inc Scand.

30d forecast means current/next month up to ~30d ahead and is issued at ~end of previous month.

45d forecast means ~15d to 45d ahead and is issued mid of previous month; etc for 75d.

Forecasts issued can include re-issue of copies of previous without update and appropriately labelled [even if no changes have been (yet) made] - so subscribers know they have not missed a forecast (update). BI 100d, 90d, 75d, 45d and 30d can be the same but there normally will be extra detail and/or (sometimes) changes at any stage or extra stages espec for 45d & 30d issues. The basics of any forecast normally stay unchanged from ~6m ahead to 30d fullest detail in ~85% of cases.

WeatherAction is a major player in the Global Warming/Climate Change debate

We point out that the world is now cooling not warming and there is no observational evidence in the thousands and millions of years of data that changes in CO2 have any observable effect on weather or climate in the real world.

There are no scientists in the world who can produce such observational data and we challenge anyone reading this to send us such observational evidence from the real world or find someone who can and get them to produce it. There is only effect the other way, namely that ocean temperatures control average CO2 levels due to basic laws of physics about the soluability of CO2 gas in (sea) water. Boris Johnson, the (then) Mayor of London has expressed interest in what we say: see article

WeatherAction Business summary:

WeatherAction are world leaders in Long range weather - and climate - forecasting and produce detailed weather forecasts to resolution of a few days months ahead for Britain & Ireland, Europe and USA +South Canada, and climate forecasts up to 20 years ahead.

The forecasts are based on predictable aspects of solar particle and magnetic activity and sun-earth connections and their modulation by lunar effects. The unique method developed by Piers Corbyn - WeatherAction founder, astrophysicist, theoretical physicist and weather & climate physicist & forecaster - is kown as The Solar-Lunar-Action-Technique (SLAT) of Long-Range forecasting.

Independent peer-reviewed measures of WeatherAction forecasts, monitors by insurance loss-adjusters, and scientific weather bets through William Hill show the significant skill of WeatherAction forecasts weeks and months ahead while other ('classical' / Numerical modelling) methods have no-skill (see www.WeatherAction.com  Forecasts / accuracy).

Forecasts out to 4/5months ahead for Britain and Ireland, Europe and USA are sold at low charges on-line via www.WeatherAction.com .

Forecasts further ahead - eg up to 12 months ahead are available directly from WeatherAction.com

Most regular customers are farmers, commodity and energy traders, water companies, holday operators, event planners ( eg weddings, holidays, festivals), weather-sensitive retail and outdoor-pursuits.

WeatherAction forecasting powers are greatest for extreme events - storms and heatwaves / cold spells. WeatherAction's unique R-periods ('Red' weather periods, topmost R5 and R4), forecasts, now recognised world-wide by scientific forecasters and extreme-event analysts have unique skill in predicting most likely periods of extreme thunder and tornado risk and Tropical Storm formation and Rapid development. The same / related periods are also used for Extreme Earthquake risk trial forecasts.

WeatherAction significant forecast successes with detail where applicable to a few days include:-
- VERY Wet summers Britain & Ireland 2007, 2008, 2009 (when UK MetOffice precicted 'BBQ' summers!);
- West Russian Heatwave and the date of it's ending in August 2010;
- UK coldest (and very snowy) December for 100 years Dec 2010;
- Extreme deadly tornado swarms eg Joplin Missouri USA May 2011;
- Hurricane Irene USA East coast predicted in detail 12 weeks ahead;
- The year without a summer - extreme deluges and hail - Britain & Ireland 2012;
- Very Extreme deluges and hail July 2012 USA and Europe;
- V late Spring BI 2013 (Piers/WA won British Asparagus Assoc competition for market readiness);
- Late Oct Storm ('Piers Corbyn's Storm) S England +NW Euope 28Oct 2013, predicted 6mth ahead;
- Extra-ordinarily cold (displaced polar vortex) Winter/Springs 2014 and 2015 (East) USA+S Canada.

- Formidably skilled forecasts for April and May 2016 in BI, Eu and USA.
NONE of the above were predicted long-range by any other forecasters.

Forecast Subscription access details - ensuring your updates

30d forecasts: Access is to 28th of last month subscribed (uploads ~29-31st)

Subs start in the same month for payment by 20th of month. From 21st the Sub is deemed to apply from the next month and the current month is free.

45d (BI) forecasts:Access is to 14th of last month subscribed (Uploads ~15-17th)

- so that next month which loads 15th onwards is excluded. 30d for that month is also loaded.

45d subs start for the following month for payments made till 27th. From 28th subs are deemed to start from the month after that and months prior to that are free.

75d (BI) forecasts:Access is to 14th of month before last month subscribed

- so that next 75d month which loads 15th onwards is excluded. 28th, as 45d, is sub start switch date.

100d (BI) forecasts = Season ahead plus 10 days: Access is to 20th of 2nd month before last month subscribed. Sub start switch date is 21st

- so that next 100d month which loads 22nd onwards is excluded. 75d loads on ~15th

AND 45d access is given to 14th of last month subscribed

so 45d, 30d forecasts for the months load.

150d (5 months) ahead access is to 28th of month concerned and updates on 29th onwards.
