For the most comfortable weather at Disneyland in California, the "sweet spot" is typically found in late April to early May or late September to mid-October. During these months, you avoid the intense "90-degree-plus" heat of the summer and the rainy unpredictability of the winter. April and May offer mild highs in the low 70s, though "May Gray" can bring some morning cloud cover that usually burns off by midday. September and October provide warm, sunny days with average highs in the 80s, perfect for enjoying outdoor attractions without the oppressive humidity found in Florida. For those who don't mind slightly cooler temperatures, January is a hidden gem with clear, sunshiny days and highs in the 60s—ideal for wearing a "spirit jersey" all day. However, if you want to avoid the "June Gloom" (persistent morning clouds) or the peak summer heat of July and August, the transition months of spring and autumn offer the most reliable blue skies and pleasant walking temperatures for a full day in the parks.
