Both diurnal and seasonal, while oceanic islands and the western parts of continental have a heavier rainfall, higher humidity and more uniform temperatures. There are numerous exceptions however, and local climates are still further modified by altitude, proximity of mountain, etc. Near to the equator, climate is almost synonymous with weather as there is so little variation in the latter.
