The start of the period will bring a mix of conditions. In the northwest, rain and strong winds are likely, with a possibility of gales in the far northwest. In the southeast, the weather is expected to remain drier for longer with spells of sunshine. Confidence over the details remains low for the start of the period, however. As the period progresses, expect changeable and unsettled weather, primarily due to nearby low pressure. Periods of rain and showers are expected for most, especially in the north and the west. Temperatures are expected to be nearer to normal, possibly slightly below at the start of the period, with south and southeastern areas potentially experiencing warmer conditions.

Confidence in the forecast for the end of September to early October decreases during this period. Weather patterns are likely to become less clear as we move into late September. However, there is likely to be a higher incidence of high pressure than usual for this time of year, possibly resulting in settled weather conditions. Temperatures are expected to be warmer than average.
