Vacation - planning day with weather service

I am spending vacation at the polish Baltic Sea shore. The place, where the summer weather is a mix of wind, sun and rain. In that circumstances, good weather forecast service is really helpful.
I am checking weather forecasts at ICM institute site. It uses numerical prediction model for 2 day short horizon forecasts. The forecasts are detailed and precise for selected area. Unfortunately forecasts are available only for Europe. That forecast service is really good. Many times it saved me biking in the rain.
So now I am checking when it stops raining so I could walk on the beach.
