This is the best forecast in the world for knowing what will happen in the next few days. Beyond about day 5, meteorological forecasts begin to destabilize and produce inconsistent results. Our professional trader clients need a better forecast at one week, one month, and 6 months. So we worked with climate scientists to develop the first operational weather forecast which draws from both meteorology and climatology. The result is an accurate and stable weather forecast out to 30,60 and 90 days. This model is the Melita Weather Associates Long Range Weather Model. Melita’s model has taken nearly 20 years to perfect. Over much of that time our forecasts were available only to utilities and hedge funds who made millions trading on the highly volatile energy markets. Energy traders love our model because it often disagrees with the government model, and more often than not the Melita model correctly predicts the coming season. Now the Melita model has been harnessed to give you the only free long range weather forecast in a mobile app. ## Key features - Proprietary long-range forecast model - Insights beyond 5-day horizon - Comparison with historical averages - Sky State Calendar - Draws from meteorology and climatology ## Recent user reviews (6 of 6) All indexed reviews: https://appshunter.io/ios/app/30-day-weather/id1438670079/reviews.md ### 1/5 — Why is this on the App Store? *2024-04-10* This app has not been updated in four years and it doesn’t open on my phone. I thought I found a long range weather forecast app…I was wrong. Don’t waste your time. ### 1/5 — Not accurate *2021-05-25* Used this to help plan a trip and began watching the weather 30 days in advance. Weather forecast went from being sunny in 90s up to 100 then down in the 80s. When we arrived at our destination the highs were in the 60s and 70s with rain. ### 1/5 — Only works in the USA *2021-05-24, version 1.1* Does not work outside the USA - would have been helpful to state this in the description!! ### 1/5 — 30 day weather app *2019-10-10* Had it for awhile then suddenly it’s blank and can’t get the weather, very disappointing Great program is working fantastic **Developer response:** Sorry for this inconvenience.
