    @jhon-stone said in Why are weather forecasts sometimes wrong?: @Miloslav-Tlamicha said in Why are weather forecasts sometimes wrong?: Forecasts can be occasionally wrong. This can have several causes: Difficult and very changeable weather conditions: with a sharp climatic boundary between adjacent areas. In such weather conditions, forecast differences of 50-100 km will affect massively the quality, since the predicted temperatures and precipitation will often occur within only a few kilometers of the selected location. Very small-scale differences in the mountains or along coastlines can cause very small-scale differences, which can not be reproduced even by a good weather calculation. Missing or wrong observations: the observations are used to initialize the calculations, and an incomplete initialization may produce misleading results. Faulty weather calculations: such errors can occasionally occur in weather models, and can be resolved with the help of repeated and detailed observation, and detailed user feedback. Erroneous measurements: unfortunately faulty measurements are not uncommon, and deceive the observer about the actual conditions, suggesting that a correct forecast is wrong. This is a great breakdown of why forecasting remains one of the most complex challenges in science. The point about climatic boundaries is especially true—when you're dealing with coastal or mountainous terrain, a 50km shift is the difference between a sunny day and a localized storm. I deal with similar data accuracy challenges while managing the technical side of my utility portal at visit, where ensuring the right information reaches the user at the right time is critical. Whether it's weather models or automated data scripts, user feedback remains the best tool we have to identify those 'faulty calculations' and improve the system. Thanks for sharing this insight! True, user feedback is an invaluable way of verifying forecast services!

    [image: 1759153079722-2025-09-29t1300_meteogram_airquality_hd-resized.png] Meteogram Air Quality & Pollen Meteogram Air Quality & Pollen shows a 3-day forecast of air quality and pollen conditions. It visualises: • Common Air Quality Index (CAQI) scale from 1 (good, green) to 100 (bad, red). • Particulate matter: PM10 (particles ≤10 μm) and PM2.5 (particles ≤2.5 μm). • Desert dust concentrations. • Air pollution gases: ozone (O₃), sulphur dioxide (SO₂), and nitrogen dioxide (NO₂). • Pollen forecasts for selected locations (no official colour coding). How it works • CAQI uses the "background" index, not the "roadside" index, since small-scale road effects cannot be resolved by weather models. • PM10 and PM2.5 represent fine particles that can penetrate deep into the lungs; desert dust contributes to elevated values. • Ozone forms in the lower troposphere, especially in urban areas, and impacts respiratory health. • SO₂ and NO₂ mainly originate from burning fossil fuels, reacting to form harmful secondary pollutants. • Time axis uses local time valid when the forecast is created. Limitations • Forecasts are based on atmospheric models at 12 km resolution; local concentrations may differ. • Roadside measurements are typically higher than background forecasts. • Pollen forecasts lack a unified colour coding system. • Not suitable as a replacement for official air quality warnings. Best use cases • Monitoring regional air pollution and pollen exposure risk. • Supporting health-related planning for sensitive groups (e.g. asthma, COPD, allergies). • Tracking pollution trends and seasonal variations. Access Available on the meteoblue website. Extended forecast options via point+ subscription or meteoblue API. Disclaimer Neither the European Commission, ECMWF, nor meteoblue is responsible for use of the forecast information presented here. Always consult your local air quality agency in the case of alerts or high pollution events.

    Hello, and thank you for your question. The meteoblue app subscriptions on iOS and Android and the website subscriptions, such as point+, are managed separately. Your Premium subscription on the iPhone app does not include access to point+ features on the website, so a separate payment is necessary to use those services online. This separation exists because synchronizing subscriptions across app stores and the website involves complex data sharing and additional costs. Currently, app subscriptions do not grant website features, and website subscriptions do not cover app features. We hope we were able to answer your questions and wish you pleasant weather with meteoblue.

  • Discuss features, tips, and questions about the meteoblue 7-day weather forecast, including pictocast, rainSPOT, and daily weather details.

    rainSPOT The rainSPOT is a unique meteoblue visualisation showing regional precipitation around a selected location. It provides a quick overview of how rainfall is distributed in the hours preceding the indicated time. It visualises: • Precipitation totals for the chosen interval (e.g. a 3-hour rainSPOT at 11:00 shows precipitation from 08:00–11:00). • Precipitation intensity with colour-coded shading. • Spatial distribution of rainfall around the chosen location, always centred in the middle grid cell. • Precipitation types (rain, drizzle, hail, ice, snow). How it works • rainSPOT aggregates forecast grid cells: the chosen location is always placed in the central grid cell. • The radius of the outer circle is indicated on the left side of the diagram. • meteoblue models allow global coverage, including mountainous and offshore regions. • Resolution varies by region: – 3–4 km in Europe and North America for the first 3 days. – 12 km for days 4–7, or in other global regions. • rainSPOT works in combination with the pictocast, where additional details such as amount, timing, and probability are shown. Limitations • In mountainous regions, precipitation can be highly localised (e.g. only on a slope or summit), while the grid cell covers a wider area. • A forecast of 1 mm in a 10x10 km cell may represent uniform rain, patchy showers, or even localised heavy downpours. • Radar or satellite adjustments are applied where available, but local variations may still occur. • Forecast accuracy decreases for longer lead times and complex terrains. Best use cases • Identifying whether precipitation will be widespread, showery, or localised. • Tracking thunderstorm activity and precipitation fronts. • Recognising persistent rain events (monsoon, low-pressure systems). • Supporting outdoor planni

  • Discuss medium-range forecasts and how to interpret or apply them.

    Hi Miloslav, I am a very satisfied Point+ member of Meteoblue, which to my opinion is a weather service of high quality. Nevertheless, recently got confused on how to interpret the colored day and night temperature boxes in the 10 day (or actually 14 day) forecast pictures. I can not find the consistency of the background colors and black or white font of the temperature boxes in attached examples, especially when background color is bright lime green (BLG). In daytime temperatures, 14 degrees is BLG with white font, 16 degrees is BLG with black font, 17 and 18 degrees are pale beige/light yellow with black font and 19 and 20 degrees are BLG again, now with black font. I have searched on the MB website and broader (AI) for an explanation on the color use, but was not able to find one. Can you explain how the model chooses the background and font colors? May there be a different reason for choosing the colors than only the corresponding temperature? Does it reflect other weather data? Cheers, Michael.

    Hi Kai, thanks for sharing this — and for taking the time to build it. It's genuinely useful to see how developers are working with the API in practice. What's the main use case you're using it for? Always good to know what's actually getting used (and what we could make easier).

    I see what you mean. Without going through locations one-by-one, I would like to determine which locations in the world most closely match this graph. Is there any way to do this quickly?

    Hello, and thank you for your question. The observed 12-hour shift in temperature, with higher values at night and lower during the day, can be caused by either a display or synchronization issue in the meteogram or by actual meteorological conditions such as nocturnal temperature inversion, warm air advection at night, cold front passage, or cloud cover reducing daytime heating. Our 3-hourly forecast temperatures correspond exactly to the indicated hour and are not averages. The Dataset API uses sunrise and sunset times to differentiate day and night values at "00:00" and "12:00." If the temperature curve appears shifted by 12 hours, it may be due to a display problem or a misunderstanding of the time reference. We hope we were able to answer your questions and wish you pleasant weather with meteoblue.
