Typically, Ireland in the latter part of September experiences a transition from summer to autumn. This period is characterized by decreasing temperatures, shorter daylight hours, and an increased likelihood of rainfall. Average daily highs generally range from 13 to 16 degrees Celsius (mid-50s to low-60s Fahrenheit), while overnight lows can dip to between 7 and 10 degrees Celsius (mid-40s to low-50s Fahrenheit). While sunshine is still possible, cloud cover becomes more prevalent. Conditions can vary significantly across the island, with coastal areas often experiencing stronger winds and milder temperatures compared to inland regions.
Understanding the prevailing climatic conditions during this time is valuable for a range of activities. Agricultural planning benefits from awareness of typical rainfall patterns and temperature fluctuations. Tourism and outdoor recreation are also significantly impacted by the weather. Travelers can make informed decisions about clothing, itinerary, and choice of activities based on typical weather patterns. Historical weather data for this period provides valuable context for understanding long-term trends and potential variability. This information can be useful for researchers studying climate change as well as for individuals planning future trips or events.
