If you want to talk about the weather in October, you might find these useful: prognoza pogody – weather forecast jesień – Autumn Jest zimno. – It’s cold. Pada deszcz. – It’s raining. Czasem świecie słońce. – Sometimes the sun is shining. Jest ładnie. – It’s nice. Wieje wiatr. – Wind is blowing. Now, this kind of weather is not going anywhere for a while so why don’t you try to think how to say the same things in future tense? And frankly, it was the same yesterday, wasn’t it? So think about past tense as well.
