Use the city table below to compare nearby places instead of relying on a single provincial number. Mountain cities, coastal districts, basin locations, and river valleys can feel very different even when they appear on the same provincial page.
Hainan is tropical and ocean-influenced. Temperatures often stay warm across the island, so rainfall, wind, and cloud cover may be more meaningful than the small temperature differences between cities.

本页面提供海南省所有城市的详细气温数据。上方交互式地图展示了全省温度分布，不同颜色代表不同的温度区间。排行面板列出了所有监测城市，按当前温度排序。
使用7天预报功能提前规划。展开每个城市卡片可查看未来一周的温度趋势柱状图，包括每日最高温和最低温。
同一省份内的城市可能因为海拔、地形、距海远近、云量、降雨和城市热岛效应出现明显温差。建议不要只看省级最高或最低值，也要结合城市表格查看附近城市的实际状况。
如果本省包含山区、盆地、沿海或高原地区，城市之间的温度和风速差异可能更大。页面中的天气描述、最高温、最低温和风速需要一起阅读，才能更接近真实体感。

On July 20, 2026, this page compares 19 monitored cities and districts in Hainan. The current city-to-city spread is about 5.5°C. Warmer readings are concentrated around ChengMai (36.8°C), ChangJiang (35.6°C), LinGao (35.4°C), while cooler readings appear around WuZhiShan (31.3°C), SanSha (32.3°C), WenChang (32.4°C).
The city table is deliberately kept visible because local variation is often more useful than a single province label. In the latest sample, 19 monitored locations are at or above 28°C, 0 are below 10°C, 1 show rain, thunder, sleet, or snow signals, and 6 report wind at or above 6 m/s.
Hainan is tropical and ocean-influenced. Temperatures often stay warm across the island, so rainfall, wind, and cloud cover may be more meaningful than the small temperature differences between cities.
South China and coastal subtropical regions should be read through heat plus moisture. Short showers, monsoon rain, sea breezes, and tropical systems can matter more than small ranking changes. For travel, check rain and wind before assuming a warm temperature means easy outdoor conditions.
These notes turn the raw city readings into local planning context. They use the current weather sample together with public map coordinates and nearby public place-title signals, then rewrite the result for this site instead of copying article text.

7月20日，本页对比 海南省 的 19 个监测城市或区县。当前城市间温差约为 5.5°C。偏热读数集中在 澄迈县 (36.8°C), 昌江黎族自治县 (35.6°C), 临高县 (35.4°C)，偏冷读数出现在 五指山市 (31.3°C), 三沙市 (32.3°C), 文昌市 (32.4°C)。
我们保留城市表格，是因为本地差异往往比单个省级标签更有用。当前样本中，19 个监测点达到 28°C 及以上，0 个低于 10°C，1 个显示雨、雷、雨夹雪或雪等信号，6 个风速达到或超过 6 m/s。
海南受热带和海洋影响显著，各地温度通常都偏暖，因此降雨、风、云量和短时天气变化往往比城市间小幅温差更关键。
华南和沿海亚热带地区要把热度和水汽一起看。短时阵雨、季风降雨、海风和热带系统，往往比排名微小变化更关键。出行时不要只因温度偏暖就判断户外条件轻松，还要看雨和风。

建议同时查看地图、城市排行和展开后的 7 天高低温条形图。天气指南、旅行天气规划指南、天气安全指南和区域气候指南说明了如何组合这些信号。涉及预警、灾害、航空、航海或其他安全决策时，请以官方气象服务为准。
Cities can differ because of elevation, coastlines, terrain, urban heat, cloud cover, wind, and rain. Province pages include city rows so readers can compare local conditions directly.
Use the city table for local decisions. A province-level summary is useful for comparison, but it can hide major differences between mountains, basins, coastal districts, and plains.
The weather label is the latest representative condition available from the source data, such as sunny, cloudy, overcast, or rain. It is intended as a quick reference alongside temperature and wind.
No. This site is for reference and comparison only. Always consult official weather services and emergency authorities for warnings and safety decisions.

不是。本网站用于气温对比和参考，不替代官方气象预警。涉及安全决策时，请查询官方气象和应急部门信息。
海拔、地形、距海远近、城市热岛、云量、风和降雨都会造成差异，因此建议结合城市表格查看。
