How it works

About tomorrow's weather Basque speaks in the future tense, and it is built from two parts: the participle in -tu/-i and the particle -ko/-en: egin + ko = egingo, joan + go = joango. The auxiliary verb stays in the present form: Euria egingo du bihar — the rain will fall tomorrow, literally "the rain do-will tomorrow".

Note: the weather is the doer here. The rain "does", the storm "comes" (etorriko da), the day "turns sunny" (eguzkitsu egingo du). The forecast is a list of what the sky intends to do to you before lunch.
