Castellón/Castelló after the rain of 1–3 October: the model's window runs from 18 to 31 October

If you're working out when to head into the woods in the province of Castellón/Castelló (Castellón/Castelló, Valencian Community) this year, the start of October gives you a reason to look at the second half of the month. From 1 to 3 October 2026 there was heavy rain here: 20 mm or more fell on 92% of the territory. The median for the province was 41.7 mm, meaning that on half of the territory more fell and on the other half less. For the MicoRadar model this is a triggering rain, and its window falls on 18–31 October ¹.

Is that a lot?

Yes, especially after the dry weeks before it. From 17 to 30 September the median rainfall for the province was only 9.9 mm. Then, over three days, noticeably more fell, and across almost the whole province rather than just in patches ¹.

This is about weather that has already happened, not a forecast. MicoRadar takes daily rainfall from a grid with a one-kilometre step. It is a model-based weather analysis, refined with measurements from AEMET (Spain's state meteorological agency). There are no observations from the forest and no mushroom pickers' finds in this data ¹.

When should you expect the window?

From 18 to 31 October 2026. The model treats a rain as a trigger for days that come 15–30 days after it. For the rain of 1–3 October, that is exactly the second half of the month ¹.

The window is a period when one of the conditions needed for fruiting is met: enough rain fell at the right time beforehand. This is a calculation, not an observation, and not a promise that mushrooms will appear ¹.

Does rain mean there will be mushrooms?

No. A triggering rain is only one of the conditions. Besides it, the model looks at temperature, soil moisture, the species' season and the woodland. If, for example, it turns colder or the soil dries out quickly, the picture for the same dates may look different. So millimetres of rain on their own don't tell you what you'll find in the woods ¹.

You can see how these conditions add up day by day on the map of the area. To compare with neighbouring provinces, open the general forecast map. The map is recalculated every morning, so you can keep an eye on the window starting on 18 October ahead of time and see how it changes ¹.

The rainfall data in this text runs up to 3 October 2026. For the latest calculation, see the MicoRadar map.
