Premium

Hi there.

I don't know if I am posting in the correct place but I'm new here.

I just paid for the premium version and I am currently feeling ripped off. If someone could explain the difference for me other than hourly chart changes and 4 hour updates that would be great. It said high resolution data and it literally is exactly the same.

Cheers,

Mike.

High resolution data must be understood as more data per day. When you get hourly forecast steps you get more data than 3 hr forecast steps in 24hr.

But this has nothing to do with geographic resolution which depends on the weather model grid.

About "Hourly chart changes":

it means you get on map all weather forecasted values, which generally have hourly validities
standard Windy only displays 3h forecasted values, which is 3 times poorer

About "4 hour updates" (I assume you meant "4 times updates by day"):

it means you get all weather forecast model runtime series
generally, models are computed 4 times by day at 00h, 06h, 12h and 18h UTC (i.e. the "runtime")
forecasts data (i.e. the "validities", values valid at runtime+Nh) computed at each runtime are available on model providers' site 3-4h after each runtime
each new runtime computes better values compared to the previous one
Standard only displays validities for 2 runtimes/day (00h and 12h UTC I guess), while Premium provides all 4 runtimes
e.g., if today at 22h UTC you display weather forecast for tomorrow at 10h UTC, you actually get:
** Standard: validity +22h computed at runtime 12h UTC
** Premium: validity +16h computed at runtime 18h UTC
in this sample, Premium gets better forecast for two reasons:
** the more recent the model, the more accurate it is (model runtime 18h is better than model runtime 12h)
** the shorter the period, the more accurate the calculation (validity +16h is better than validity +22)

@vsinceac said in Premium:
The more up-to-date the model, the higher its accuracy (a model with a runtime of 18 hours is preferable to one with a runtime of 12 hours). Very useful for me.
