SINGAPORE: Prevailings winds are forecast to blow from the southeast on Thursday (Oct 15), and occasional slight haze can be expected, said the National Environment Agency (NEA).

In an advisory, the agency said that there was an improvement in the haze and visibility conditions on Wednesday "due to showers over Singapore and the surrounding sea areas in the pre-dawn hours". It added that the prevailing winds were forecast to continue blowing from the east-southeast throughout the day. At 5pm, the 24-hour PSI was 90-103, which is in the high end of the Moderate range and low end of the Unhealthy range.

NEA said that given the air quality forecast for the next 24 hours, healthy persons should reduce prolonged or strenuous outdoor physical exertion. It added that the elderly, pregnant women and children should minimise such activity, while those with chronic lung or heart disease should avoid it altogether.

S’pore experiences hazy conditions as PSI climbs into moderate range

S’pore experiences hazy conditions as PSI climbs into moderate range

PUBLISHED: MARCH 7, 8:35 PM
SINGAPORE – Air quality worsened today (March 7) as Singapore experienced hazy conditions since the late afternoon.

As at 8pm, the three-hour Pollutant Standards Index (PSI) was in the moderate range of 71. The 24-hour PSI was between 42 and 50, while the PM2.5 was between 29 to 33 μg/m3.

The National Environment Agency (NEA) said PSI readings have been elevated since 5pm.

The haze may be due to hotspots to the north of Singapore, blown in by the prevailing northeasterly winds, said the NEA. A total of four hotspots were detected in Peninsular Malaysia today, and 35 hotspots in Sumatra.

“The hazy condition is expected to persist overnight. NEA will continue to monitor the situation and provide updates as necessary,” said the agency.

Weather Outlook: 16 - 31 July 2009

REVIEW 1 - 14 July 2009

During the first two weeks of July 2009, about three quarters of Singapore experienced above average rainfall. The highest rainfall of 130 mm to 150 mm (80% to 105% above average) fell over the City and Kallang areas. Rainfall was lowest over the Choa Chu Kang and Bukit Panjang areas where 40 mm to 60 mm (20% to 45% below average) of rain was recorded.

Weather Outlook: 16 - 31 July 2009

1. For the next fortnight, the region should continue to experience Southwest Monsoon conditions. The low-level winds over Singapore are expected to blow predominantly from the southeast or southwest.
   
   
2. During the fortnight, showers with thunder are expected on 4 to 5 days between the morning and early afternoon. In addition, showers with thunder accompanied with occasional gusty winds due to “Sumatra” squalls are likely on 2 to 3 days in the pre-dawn and early morning.
   
   
3. As periods of consecutive dry days are common in the region during the Southwest Monsoon season, Singapore could experience slightly hazy conditions on a few days. Rainfall for July 2009 is likely to be above average for most parts of Singapore.

Note: I can't access the information last few days, maybe they have change the links or migrate their servers.

Cool winds ushering in CNY

Cool winds ushering in CNY

SINGAPORE'S cool.

While the country has earned kudos for being a lot more hip over the years, it has also enjoyed a welcome spot of cool, windy weather lately.

And such conditions should prevail during Chinese New Year next week which should make going out and about - well - a breeze.
