WXSIM FORECAST

WU FORECAST

ACTUAL

WXSIM values come from latest.csv, frozen at capture. WU values come from the Weather Underground 5-day forecast: days 1–6 frozen on the start-day morning, day 7 added from the next morning's forecast. Actuals are Weather Underground PWS observations: completed days are written from 06:00 the following morning. Pale bars (*) are provisional: today's running values, or a completed day awaiting its 06:00 daily record. They refresh every 30 minutes and are not scored.

Forecast only at present. No completed Weather Underground daily observations have yet been added to this 7-day period. Actual bars will appear automatically as the archive is updated.

Only days on which WXSIM, WU and the actual observation all exist are scored, so both forecasts are compared on identical ground. The average error % uses High, Low, Rain and Wind. The WU daily forecast has no gust, solar radiation, dew point, wet bulb or pressure values, so those remain WXSIM-only.

Maximum & Minimum Temperature

WXSIM and WU forecasts versus actual daily temperature (°C)

Rainfall

WXSIM and WU forecasts versus actual daily total (mm)

Maximum Sustained Wind

WXSIM and WU forecasts versus actual (km/h)

Maximum Wind Gust

WXSIM forecast versus actual — the WU daily forecast does not include gusts (km/h)

WU forecast: not available — the Weather Underground 5-day forecast contains no gust values

Maximum Solar Radiation

WXSIM forecast versus actual daily maximum — not included in the WU daily forecast (W/m²)

WU forecast: not available — the Weather Underground 5-day forecast contains no solar radiation values

Additional Metrics — forecast by both WXSIM and WU

Actuals are the station's daily record; pale bars (*) are provisional and refreshed every 30 minutes.

Error % uses a symmetric forecast-versus-actual percentage difference (0% = exact match; maximum 200%). WXSIM Daily Error % is the mean of the available High, Low, Rain, Wind, Gust and Solar errors; WU Daily Error % is the mean of High, Low, Rain and Wind (WU supplies no gust or solar forecast) — use the Head-to-Head panel for a like-for-like comparison. pending = WU day 7 awaiting the next morning's capture; * = provisional — today so far, or a completed day awaiting its 06:00 daily record (refreshed every 30 minutes, not scored); n/c = not captured (date had passed before WU capture began). Temperature percentages near freezing (0 °C / 32 °F) can appear large and should be interpreted as a comparative forecast-error indicator.
