How reliable is a long-range forecast?
The first three to five days for Tessenderlo-Ham are the most dependable. After about a week, a forecast gives a trend rather than an exact figure: the daily temperature can be off by several degrees and the timing of rain can shift by a day or more. Use the later days to plan broadly and check the page again as the date approaches, since it is updated several times a day.

How far to trust the 15-day forecast for Tessenderlo-Ham
A forecast loses detail the further ahead it looks, so the 15 days for Tessenderlo-Ham are not equally dependable. Read them in bands, using the figures for this forecast.
- Days 1 to 3 (Sunday 15 Nov to Tuesday 17 Nov): the most dependable stretch. Daytime highs average 10.6 °C, and at least 1 mm of rain is forecast on 3 of the 3 days. Use these days for fixed plans, travel and outdoor jobs that cannot move.
- Days 4 to 7 (Wednesday 18 Nov to Saturday 21 Nov): the pattern is usually right, but timing can slip by a day. Highs average 9.6 °C with 3 wet days out of 4. Weather in Belgium is driven mostly by Atlantic disturbances arriving from the west, often one after another. A small change in the speed of a front moves rain and wind from one day to the next.
- Days 8 to 15 (Sunday 22 Nov to Sunday 29 Nov): treat as a trend. Highs average 9.9 °C and at least 1 mm of rain is forecast on 5 of the 8 days, but the models disagree more and more at this range. Read it as warmer or cooler, wetter or drier than usual, not as a day-by-day promise.
Tessenderlo-Ham against the 1991-2020 normal for November
The 1991-2020 normal for November in Tessenderlo-Ham is a daytime high of 9.9 °C and a night-time low of 4.8 °C. Over these 15 days the forecast gives an average high of 9.9 °C and an average low of 4.7 °C: highs are close to the normal (a difference of 0.0 °C) and lows are close to it (a difference of 0.1 °C).
A gap of one or two degrees is ordinary variation from year to year. A gap larger than that over a fortnight points to an unusually warm or cool spell, often tied to a persistent high-pressure area or to a run of northerly or southerly outbreaks. Highs and lows can move in different directions: cloudy nights are mild, clear nights are cold.
For rain, the November normal in Tessenderlo-Ham is about 67 mm for the whole month. Pro rata, 15 days would share about 34 mm; the forecast adds up to 82.4 mm, around 245 % of that share. Rain falls in bursts, so a single front can account for most of a fortnight's total, and the pro rata figure is only a yardstick.
