Wellington's climatological mean maximum for April consistently registers near 17°C. The 15°C threshold lies comfortably within the standard thermal envelope for this period, implying a routine diurnal warming. Current synoptic models indicate a high likelihood of prevailing westerly flows, mitigating any significant cold air advection that would suppress temperatures below this level. Expect a standard autumn day exceeding the benchmark.

Wellington's late April mean max hovers near 16°C. With current ridge build-up, expect robust diurnal heating. Historical 29/04 data shows 4/5 years above 15.5°C. The probability of topping 15°C is high. 90% YES — invalid if significant southerly advection.
