How to Use WeatherNext 3: From Location to Decision
A forecast only helps if it answers a specific question. This guide walks through the four moves that turn a global model into a usable answer: pick the place, pick the variables, describe the decision, and read the progression. If you first want the vocabulary, skim how to read the hourly data.

The four moves of a useful forecast
Each step narrows the question. Skipping one is the usual reason a forecast feels generic.
Choose the real location
Use the coordinates of the asset or area you care about, not the nearest large city. At 5 km resolution, a field and a city centre 40 km apart can differ meaningfully.
Select variables deliberately
Give every variable a job in the decision. Precipitation, wind, temperature, humidity, radiation and cloud cover each answer a different question.
Describe the decision
State the action, the time window and the threshold at which your plan changes. A threshold turns a description into a comparison against your operating limit.
Read the progression
Follow how conditions evolve across the window rather than reading one timestamp, and compare successive hourly runs before you commit.
Match the variables to the decision
Most operators only need two or three variables. Requesting everything dilutes the answer, so start from the decision and work backwards to the data you need.
Outdoor work blocks
Precipitation, wind speed and temperature decide whether a crane lift or a pour can run inside its window.
Solar sites
Radiation, cloud cover and temperature explain how much a photovoltaic array will actually produce.
Frost and fog risk
Temperature and humidity together, with wind, tell you whether a cold night turns into frost or stays clear.
Wind assets
Hub-height wind, including the 100 m level, plus temperature for icing and turbine limits.
Common mistakes when using WeatherNext 3
None of these are model problems. They are reading problems, and they are easy to fix.
Using a city centre for a rural asset
At 5 km resolution the difference is real. Use the coordinates of the site, not the nearest town.
Treating one run as final
Hourly refresh exists because forecasts move. Compare the last two or three runs before cancelling a plan.
Reading temperature without humidity
Frost, fog and crop stress depend on moisture as much as on heat, so read the pair together.
Ignoring wind direction
Speed tells you whether a window is workable. Direction tells you whether it is safe.
Planning on a daily average
The daily number hides the two or three hours that decide the outcome. Work at hourly resolution.
Skipping official warnings
For safety-critical work, check the national weather service alongside any forecast tool.
