Future Weather Planner
Description
I created a Siri Shortcut that gives you a detailed weather summary for any dates you choose, based on historical weather data for your exact location.
What it does:
• You choose your dates and location (city).
• It pulls 30 years of historical weather data from Open-Meteo.com and calculates long-term averages, extremes, and rain patterns for those dates.
• It also analyzes the last 3 years, so you can see recent temperature and rain patterns to spot more current trends.
• It automatically saves the data to avoid unnecessary API calls, and it only updates if the data is over 6 months old (to save on requests and make it faster).
What the output includes:
For your chosen dates and city, you’ll get:
• High and low temperature probabilities for the last 3 years (short-term trend).
• Average rain chance and average rain amount for the last 3 years.
• 30-year record highs and lows, plus average temperatures (long-term trend).
• Probability of having rain-free days across both 3-year and 30-year data.
• All of this is shown in a simple summary format.
How the predictions work:
This is probability-based, not assumption-based. I’m not guessing the weather for your future dates — instead, I’m calculating:
• How often it was rainy, dry, hot, cold, etc., for those same dates over the past 30 years.
• How the last 3 years compare to the 30-year average.
• The results give you a data-driven outlook on how likely certain weather conditions are for your selected dates.
Why this is useful:
• Planning vacations, weddings, outdoor events, etc.
• Understanding seasonal shifts (like if spring is arriving earlier/later).
• Knowing if the weather is trending hotter, colder, wetter, or drier for specific dates in your area.
